Properties


• property AWSHeight as %Integer [ InitialExpression = ..#DEFAWSHEIGHT ];

• property Curr3270Header as %String(TRUNCATE=1) [ InitialExpression = "xxxxx" ];
Current Header block for 3270E data
• property NoReacknowledgements as %Boolean [ InitialExpression = 0 ];
If this is set, don't re-acknowledge options we have already acknowledged once
• property ResponseID as %Integer;
integer for response count in 3270E header response mode
• property TermTypes as %String(TRUNCATE=1) [ InitialExpression = ..#DEFTERMTYPES ];
List of terminal types to claim to support, semicolon separated
• property TranslationTable as %String(TRUNCATE=1);
Name of translation table to use for importing and exporting character text

Methods


• method %OnNew(pBaseStream As %IO.I.Stream = "%IO.Socket") as %Status
This callback method is invoked by the %New method to provide notification that a new instance of an object is being created.

If this method returns an error then the object will not be created.

It is passed the arguments provided in the %New call. When customizing this method, override the arguments with whatever variables and types you expect to receive from %New(). For example, if you're going to call %New, passing 2 arguments, %OnNew's signature could be:

Method %OnNew(dob as %Date = "", name as %Name = "") as %Status If instead of returning a %Status code this returns an oref and this oref is a subclass of the current class then this oref will be the one returned to the caller of %New method.

• classmethod CP037ToLatin1(pData As %String)
• method CharExport(pData As %String) as %String
• method CharImport(pData As %String) as %String
• method Close(Output pSC As %Status) as %Boolean
Close the current stream
• method GetOption(pName As %String, Output pSC As %Status) as %String
• classmethod Latin1ToCP037(pData As %String)
• method Open(pHost As %String = "", pPort As %String = "", ByRef pTimeout As %Numeric = -1, Output pSC As %Status) as %Boolean
• method Read(pMaxReadLen As %Integer, ByRef pTimeout As %Numeric = -1, Output pSC As %Status) as %String
Read until pMaxReadLen chars are gotten or pTimeout expires On return, if pTimeout is unchanged it means the full timeout period expired. If the timeout period expired and the returned string is shorter than pMaxReadLen, then AtEnd will be 1.
• method ReadLine(pMaxReadLen As %Integer, ByRef pTimeout As %Numeric = -1, Output pSC As %Status, pLineTerminator As %String = ..LineTerminator) as %String
Read until pMaxReadLen chars are gotten, pTimeout expires, or a LineTerminator character is found. On return, if pTimeout=0 it means no timeout occurred. If pTimeout=0 and the returned string contains the full pMaxReadLen characters, it means no LineTerminator was encountered yet, even if the following character would be a LineTerminator. If pTimeout=0 and the returned string is shorter than pMaxReadLen, then either a LineTerminator or the End Of Stream (AtEnd = 1) was encountered. If pLineTerminator is defined, then the line is read until one of the given characters is encountered. On return, pLineTerminator contains the encountered character(s) if any.
• method ReadRaw(pMaxReadLen As %Integer, ByRef pTimeout As %Numeric, Output pSC As %Status) as %String
• method Reset(pStream As %IO.I.Stream, pTimeout As %Numeric = 10, Output pSC As %Status)
• method SetOption(pName As %String, pVal As %String, Output pSC As %Status)
• method Write(pData As %String = "", pFlush As %Boolean, Output pSC As %Status)
Write pData to the stream buffer. If pFlush is True, ensure that the data are actually sent to the stream.
• method WriteLine(pLine As %String = "", pFlush As %Boolean, Output pSC As %Status)
In in 3270(e) mode, writes out a record with header and terminator (IAC-EOR) Otherwise, writes out the line followed by the standard ..LineTerminator character(s)
• method WriteRaw(pData As %String = "", pFlush As %Boolean, Output pSC As %Status)
• classmethod escape(str As %String) as %String
• method processIACs(pData As %String, Output pReplied As %Boolean, Output pSC As %Status) as %String
• classmethod toAscii(pStr) as %String
