stream class %Library.Routine extends %CharacterStream, %AbstractStream

The %Routine class provides a way to create and manipulate routines stored within a database.

The %Routine class provides a stream interface (see %AbstractStream) that allows you to read existing routines as well as create new one programmatically.

%Routine includes methods to save and compile modified routines.

For example, the following code creates, saves, and compiles a simple ObjectScript routine (note that lines of code start with a space character):

	Set routine = ##class(%Routine).%New("MyRoutine.MAC")
	; Write lines of code to the routine
	Do routine.WriteLine("MyRoutine")
	Do routine.WriteLine("Tag()")
	Do routine.WriteLine(" Write ""This is my routine"",!")
	Do routine.WriteLine(" Quit")
	; save the routine
	Do routine.Save()
	; compile the routine
	Do routine.Compile()

Properties

• property Generated as %Boolean [ InitialExpression = 0 ];
True if this routine is generated from something else
• property IsModified as %Boolean [ InitialExpression = 0 ];
• property LanguageMode as %Integer [ Calculated ];
The language mode of this routine
• property Locked as %Integer [ InitialExpression = 0 ];
Number of times this routine has been locked.
• property Name as %String [ Calculated ];
The name (without extension) of the routine associated with this object.

This is for backwards compatibility only.

• property Namespace as %String [ Calculated ];
Return the namespace this routine is from
• property RoutineName as %String;
The name of the routine.
• property RoutineType as %String;
The type of the routine.
• property RoutineVersion as %Integer;
• property TimeStamp as %TimeStamp;
• property UpToDate as %Boolean [ Calculated ];
For INT routines if this is compiled from a MAC then return true if the INT is up to date with the MAC, but if the INT is different to the MAC, e.g. it was modified and saved directly or the MAC was modified and saved but not compiled then it will return false.

For MAC routines it will be true if the generated pcode from compiling this MAC is up to date and false if recompiling this MAC would generate different pcode, so either the MAC has changed or the pcode has changed.


Methods

• classmethod %ExistsId(id As %String) as %Boolean
Checks to see if the object identified by the ID id exists in the extent.

Returns %Boolean TRUE is it exists, FALSE if it does not.

• method %IsModified() as %Integer
Returns true (1) if a property of this instance has been modified, otherwise false (0). A TRUE result does not necessarily mean that any property has actually been changed. If %IsModified() returns false then the object has not been modified. There are some situations where we simply cannot efficiently detect a change in value. In these cases we will set the modified status of the property.
• method %ObjectModified() as %Integer
This method is somewhat similar to %IsModified but it also checks to see if swizzled references would cause the object to become modified should they be serialized. This works on the assumption that a reference to a persistent object will never be modified if the ID has already been assigned. For references to serial objects, a call to %ObjectModified indicates whether or not the serialized value is different. If the reference to a swizzled object is different from the initial object state then the $$$objModAll macro will already return true. Reference the Set code. Returns true (1) if this instance has been modified, otherwise false (0).
• classmethod CheckProtect(name As %String) as %Boolean
Check if we are allowed to save this routine in this namespace
• classmethod CheckSyntax(ByRef Source As %String, ByRef Errors As %String, LanguageMode As %Integer = 0) as %Status
This function syntax checks INT source code.
Source - source (INT) code; either a single line stored in a variable, or an array where: array(0)=#lines, array(1-n)=source
Errors (byref) - Returned array of errors detected by compiler
LanguageMode - language mode, 0-10 (optional, default 0)
• method Clear() as %Status
Clear the contents of this Stream from permanent storage. This will remove the permanent stream storage and any temporary stream and initialise the stream to its initial state that it starts in, including removing all the stream attributes.

Returns a %Status value indicating success or failure.

• method Compile(qspec As %String) as %Status
Compile this routine. The qspec is the standard objects qualifiers described in 'Do $system.OBJ.ShowQualifiers()'.
• classmethod CompileAll(Flags As %String = 0, IO As %String = $p, ByRef Count As %Integer, ByRef Errors As %Integer, MultiCompile As %Integer, Journal As %Integer, KeepSource As %Boolean = 1) as %Status

MultiCompile - If true (default) then use multiple jobs to do the compile
Journal - If true (default) then journal the compile, if false disable journaling for compile
KeepSource - If true (default) then keep INT code from compiling a MAC, if false then do not save INT code
• classmethod CompileList(rtns As %String, qspec As %String) as %Status
Compile a list of routines in the current namespace. Pass this a comma separated list of items, which can include wild card characters e.g. 'test.mac,abc*.int' or pass in a subscripted array with the routine name as the subscript. It will return an error %Status. If you do not wish to use multicompile then pass in /multicompile=0
• classmethod CompileSelected(Mask As %String = "*.*", Flags As %String = 0, IO As %String = $p, ByRef Count As %Integer, ByRef Errors As %Integer, MultiCompile As %Integer, Journal As %Integer, KeepSource As %Boolean = 1) as %Status

Mask Selection mask of which routines to compile. This mask is passed to %Library.Routine.RoutineList() and must be in a format it understands.
Flags Bit string of options to method.
Bit 0 - Suppress syntax error display.
Bit 1 - Suppress output to principal device.
IO Already open device to send the output to. For example, "c:\a.out"
Count (by ref) Number of routines compiled.

• classmethod Delete(rtnname As %String, flag As %String = 0, supressbackup As %Boolean = 0, nsp As %String = $namespace) as %Status
Delete the routine rtnname. The parameter flag specifies now much to delete. The options are:
  • 0 - Delete entire routine, for a MAC routine this will delete MAC, INT, OBJ. For an INT routine it will delete INT and OBJ, for a INC routine it will only delete the INC, for a BAS routine it will delete the BAS and the OBJ code.
  • 1 - Delete just the named routine, for example for a MAC routine it will only delete the MAC and it will leave the INT and OBJ if present.
  • 2 - Delete all the source code but leave any OBJ code.
This returns a %Status code to show if it worked or not. If you pass a name like 'test.mac;*' it will delete all backup versions of this routine. If the routine name which is passed does not exists, the method will return success.
• classmethod DeleteStream(sid As %ObjectIdentity) as %Status
Deprecated method, use %Delete instead. Deletes the stored stream identified by oid. This will not remove the stream attributes of any saved streams, it will just remove the stream data. If you need to clear the attributes as well you will have to call Clear on the stream object.
• classmethod Exists(name As %String) as %Boolean
This is a class method which tests if the routine name exists.

If name consists of a routine name and an extension, such as INT, MAC, etc. then it will check for this specific routine. If it just contains the routine name it will check if either MAC, INT, or BAS exists.

	Write ##class(%Routine).Exists("Test.MAC")
	Write ##class(%Routine).Exists("Test")
• method Flush() as %Status
Flush any output in the stream not already saved.
• method GetCurrentTimeStamp() as %TimeStamp
Get the on-disk timestamp for the routine.
• classmethod GetDate(name As %String) as %TimeStamp
Return the timestamp the routine with name was last updated.
• method GetObjectVersion() as %Numeric

Return list of globals where routine and class information is stored.
Returns Names="ROUTINE,rBACKUP,rINC,rINCSAVE,rINDEX,rMAC,rMACSAVE,rMAP,rOBJ,oddDEF"
Here is some documentation on the format of the routine globals.

ROUTINE - Native .INT COS code, generated from .MAC, or generated from classes. When compiled generates .OBJ code.
ROUTINE(Name,0)=timestamp when last saved
ROUTINE(Name,0,0)=# lines in routine
ROUTINE(Name,0,1...x) = Source Lines in routine
ROUTINE(Name,0,"GENERATED")= 0/1 whether routine is generated or native
ROUTINE(Name,0,"SIZE")=# bytes in routine
ROUTINE(Name,0,"LANG")=language mode

ROUTINE(Name,"MAC")=Timestamp of .MAC code when last saved if generated
rBACKUP(Name,Type,version) - backup of ^ROUTINE, created by the command Merge ^rBACKUP(rtn,type,nextverersion)=^ROUTINE(rtn) where type="INT/MVI/BAS"

rINC - Native .INT or macro code, compiled into .MAC when included with #include directive
rINC(Name,0)=timestamp when last saved
rINC(Name,0,0)=# lines in include file
rINC(Name,0,1...x) = Source Lines in include file
rINC(Name,0,"SIZE")=# bytes in include file
rINC("ZZ","P") - Meta data used for precompiling include files

rINCSAVE - Backup of ^rINC, created by the command Merge ^rINCSAVE(rtn,nextver)=^rINC(rtn,0)

rINDEX - Index of .OBJ, .INT, and .MAC routines
rINDEX(Name,"OBJ/MAC/INC")=$lb(Time compiled,Size)
rINDEX(Name,"INT")=$lb(Time compiled,Size,Generated 0/1)

rMAC - Native .MAC Macro code which when compiled generates .INT code
rMAC(Name,0)=Timestamp when last saved
rMAC(Name,0,0)=#lines in routine
rMAC(Name,0,1...x) = Source Lines in routine
rMAC(Name,0,"INC",IncludeFileName1)=Timestamp when last include file last saved
rMAC(Name,0,"INC",IncludeFileName2)=Timestamp when last include file last saved
rMAC(Name,0,"SIZE")=# bytes in routine

rMACSAVE(Name,Type,version) - backup of ^rMAC, created by the command Merge ^rMACSAVE(rtn,nextver)=^rMAC(rtn,0)

rMAP - Debug map used by the debugger and for error trapping
rMAP(Name,"INT","MAC",offsets)=$lb(debuginfo)
rMAP(Name,"MAC","INT",offsets)=$lb(debuginfo)

rOBJ - Compiled .INT code
rOBJ(Name,"INT")=timestamp of .INT code when compiled
rOBJ(Name,0...n)=Compiled object code

oddDEF - Source code for classes
oddDEF($zcvt(Name,"U"),....)=source code from class. Note that all of the other odd* nodes are meta data describing the class, and can be recreated by compiling the class. The rINDEXCLASS and rINDEXSQL nodes also get recreated when compiling the class.

• method LanguageModeGet() as %Integer
This is a Get accessor method for the LanguageMode property.
• method LanguageModeSet(languagemode As %Integer) as %Status
This is a Set accessor method for the LanguageMode property.
• method LastModifiedGet() as %TimeStamp
This is a Get accessor method for the LastModified property.
• method LineTerminatorGet() as %String
This is a Get accessor method for the LineTerminator property.
• method Lock() as %Status
Lock the current routine
• classmethod LockRoutine(name As %String, lock As %Boolean = 1, nsp As %String = $namespace, IModeLock As %Boolean = 0, timeout As %Integer = 0) as %Status
Lock a particular routine name. If lock is true (the default) then it locks the routine, and if false then it unlocks the routine. If a routine is derived from a class then it will lock the class name in ^oddDEF to prevent another user from attempting to edit the class at the same time this process is editing the routine. If IModeLock is True, then it will unlock the routine with the #I flag so that the node will unlock even if in a transaction.
• method MoveToEnd() as %Status
Move to the end of the stream so the next Write will be appended to the end. This allows you to read from a stream, then MoveToEnd() and append new data, where just calling Write after a read will clear the stream before writing new data.

Returns a %Status value indicating success or failure.

• method NameGet() as %String
This is a Get accessor method for the Name property.
• method NamespaceGet() as %String
This is a Get accessor method for the Namespace property.
• method OpenStream(sid As %String) as %Status
• method Read(ByRef len As %Integer = 32000, ByRef sc As %Status) as %String
Reads up to len characters from the current position in the stream. The current position is advanced by the number of characters read. Upon exit, len is set to the actual number of characters read. If a read occurs when the stream position is at the end of the stream, len will be set to -1 and Read will return a null string (""). If no len is passed in, ie. 'Read()' then it is up to the Read implementation as to how much data to return. Some stream classes use this to optimize the amount of data returned to align this with the underlying storage of the stream.

You must call Rewind if you want to read a stream from the beginning again. Calling Read after Write implicitly ends the Write operation and rewinds to the start of the stream.

Returns a string up to len characters long. The byref argument sc will return a %Status if any error occurred during the read.

• method ReadLine(ByRef len As %Integer = 32000, ByRef sc As %Status, ByRef eol As %Boolean) as %String
Read a line from the stream. This will look for the line terminator in the stream and once it finds the terminator it will return the string minus the terminator character/s. If it reaches the end of the stream before it finds a terminator it will return the data it has so far, and if you specify a maximum size in len it will only read up to this number of characters. On exit len will contain the actual number of characters read. The byref argument sc will return a %Status if any error occured during the read and the byref argument eol is true if it found the line terminator and false otherwise. So for example you can read in a stream a line at a time and output the results to the current device with:
	While 'stream.AtEnd { Write stream.ReadLine(,.sc,.eol) If $$$ISERR(sc) { Write "ERROR" Quit } If eol { Write ! } }
• method Rewind() as %Status
Go back to the start of the stream.
• method RoutineExists() as %Boolean
This is an instance method which tests if this routine exists (that is, it has been saved to disk).
• classmethod RoutineListClose(QHandle As %Binary) as %Status
• final classmethod RoutineListExecute(ByRef QHandle As %Binary, ByRef spec As %String(MAXLEN=512)="", Dir As %Integer = 1, Type As %Integer = 0, Nsp As %String = $namespace, nolang As %Boolean = 0) as %Status
• classmethod RoutineListFetch(ByRef QHandle As %Binary, ByRef Row As %List, ByRef AtEnd As %Integer = 0) as %Status
Fetch returns the next row in the query.
• classmethod RoutineListFetchRows(ByRef QHandle As %Binary, FetchCount As %Integer = 0, ByRef RowSet As %List, ByRef ReturnCount As %Integer, ByRef AtEnd As %Integer) as %Status
RoutineListFetchRows returns the next FetchCount rows in the query.
• method RoutineNameSet(newvalue As %String) as %Status
This is a Set accessor method for the RoutineName property.
• classmethod RoutinesSortByFieldClose(QHandle As %Binary) as %Status
• final classmethod RoutinesSortByFieldExecute(ByRef QHandle As %Binary, ByRef Spec As %String(MAXLEN=512)="", Dir As %Integer = 1, Type As %Integer = 0, OrderBy As %String = "Date", Nsp As %String = $namespace) as %Status
• classmethod RoutinesSortByFieldFetch(ByRef QHandle As %Binary, ByRef Row As %List, ByRef AtEnd As %Integer = 0) as %Status
Fetch returns the next row in the query.
• classmethod RoutinesSortByFieldFetchRows(ByRef QHandle As %Binary, FetchCount As %Integer = 0, ByRef RowSet As %List, ByRef ReturnCount As %Integer, ByRef AtEnd As %Integer) as %Status
RoutineListFetchRows returns the next FetchCount rows in the query.
• method Save(supressbackup As %Boolean = 0) as %Status
Save this routine.
• method SaveStream(supressbackup As %Boolean = 0, Output Refresh As %Boolean) as %Status
Deprecated method, use %Save instead. Saves the temporary copy of the stream data to a persistent location. Note that any locking or transaction handling must be done by the caller.

Returns a %Status value indicating success or failure.

• method SizeGet() as %Integer
Return the current size of the data stream.
• method Unlock() as %Status
Unlock the current routine
• method UpToDateGet() as %Boolean
This is a Get accessor method for the UpToDate property.
• method Write(data As %RawString = "") as %Status
Appends the string data to the stream and advances the current stream position by the number of characters in data.

Note that a write operation immediately following a read or rewind will clear out the existing data in the stream.

Returns a %Status value indicating success or failure.

• method WriteLine(data As %String = "") as %Status
Appends the string data along with a line terminator to the stream and advances the current stream position by the number of characters in data plus the line terminator.

Returns a %Status value indicating success or failure.


Queries

• query Compare(Nsp1 As %String, RouName1 As %String, Nsp2 As %String, RouName2 As %String)
Selects LineNo1 As %String, Line1 As %String, LineNo2 As %String, Line2 As %String
This query provides a list of all lines that differ between two given routines.
Nsp1 and RouName1 specify the first routine.
Nsp2 and RouName2 specify the second routine.
Nsp1 and RouName2 can be either an explicit or an implied namespace.
• query Find(Namespace As %String, RoutineName As %String, FindWhat As %String, MatchCase As %Boolean = 1)
Selects Line As %String, Match As %Boolean
The query returns the routine that contains FindWhat, one line per row, with two columns, Line and Match. Line is the line text. Match is 1 if Line contains FindWhat. The entire routine is returned.
• query RoutineList(spec As %String(MAXLEN=512), dir As %Integer, type As %Integer, nsp As %String)
Selects Name As %String(MAXLEN=512) As FileName/Ext, Size As %Integer, Date As %TimeStamp, Lang As %String
This query provides a list of all routines that match the pattern specified by spec.

spec may contain both * and ? as wildcards. It may also consist of more than one, comma-delimited selections. For example:
"*.MAC"
"A*.MAC"
"A?.MAC"
"A*.MAC,B*.MAC"
dir specifies the direction to search in, 1 is forwards and -1 is backwards.
type is 1 to include OBJ files in the search and the default, 0 will just include INT, MAC, INC, BAS.
nsp is the namespace to list from. If omitted, the query returns the routines from the current namespace. nsp can be either an explicit or an implied namespace.

• query RoutinesSortByField(Spec As %String(MAXLEN=512), Dir As %Integer, Type As %Integer, OrderBy As %String, nsp As %String)
Selects Name As %String(MAXLEN=256) As FileName/Ext, Size As %Integer, Date As %TimeStamp
This query provides a list of all routines that match the Spec ordered by the OrderBy. The Dir specifies the direction to search in, 1 is in assending order and -1 is in decending order.

Spec may contain both * and ? as wildcards. It may also consist of more than one, comma-delimited selections. For example:
"*.MAC"
"A*.MAC"
"A?.MAC"
"A*.MAC,B*.MAC"

The Type is 1 to include OBJ files in the search and the default, 0 will just include INT, MAC, INC, BAS.

OrderBy is one of:

  • Date - Date/Time the file was saved (the default)
  • Size - Size of the file
  • Type - Type of the file ie. INT, MAC, INC, BAS
If you wish to return the results in name order then use the RoutineList query as this is faster as it does not need to build a full list first in order to sort it correctly.
nsp is the namespace to list from. If omitted, the query returns the routines from the current namespace. nsp can be either an explicit or an implied namespace.
