abstract class %Exception.AbstractException
The %Exception.AbstractException defines the interface to exceptions
that may be caught and thrown via the Try/Catch exception handling facilities. Users wishing
to define new exception classes should inherit from this interface class. Only instances of classes
that inherit from %Exception.AbstractException may be thrown with the 'throw' command.
final method AsSQLCODE()
Return the SQLCODE value corresponding to the exception.
final method AsSQLMessage()
Return the SQL %msg string describing details of the exception.
final method AsStatus()
Convert this exception to a %Status compatible value.
method DisplayString(pLevel As %Integer = 0)
This returns a string that represents the exception. Users should feel free
to modify the format in subclasses.
Call the log function (LOG^%ETN) to log this exception.
You can view this log at the terminal with 'Do ^%ER' utility or from the system management portal.
method OutputToDevice(pLevel As %Integer = 0)
This outputs the string representation of the exception to the current device, recursively
outputing any inner exceptions.
method OutputToStream(pStream As %CharacterStream, pLevel As %Integer = 0)
This outputs the string representation of the exception to the supplied stream, recursively
outputting any inner exceptions.
method SQLMessageString(pLevel As %Integer = 0)
This returns a string that represents the SQL %msg string. Users should feel free
to modify the format and content in subclasses.
method StackAsArray(ByRef array)
DEPRECATED - use AsSQLMessage() instead. Override OnAsSQLMessage() to customize the value returned
This method sets an array that is passed by reference to the execution stack at the time of the exception.
The top unsubscripted value is the number of execution levels.
array(n) is a string that indicates how the next
level was created. It is empty for the current level. The value may be:
DO - issued a DO command
$$ - called an extrinsic function
XECUTE - issued an XECUTE command
BREAK - entered a debug prompt because of a <BREAK>
ERROR - entered a debug prompt because of an error
$ETRAP - executed a $ETRAP
CALLIN - entered via a callin
array(n,"PLACE") is the location of the last command executed at this level. It is a line reference followed
by the command number on that line.
