Class-Based Exceptions for Release 7.0, EhP2
2. Keep context of an exception
Other versions: 7.31 | 7.40 | 7.54
Modification 1
Resumable exceptions
Before Release 7.0, EhP2, the context in which a
class-based exception was raised was always emptied completely. All procedures called between the
raising of the exception and any handler were deleted with their local data before the handler was executed. The program could only resume after the TRY control structure of the handler.
As of Release 7.0, EhP2,
class-based exceptions can be raised and propagated as resumable exceptions. The new addition RESUMABLE can be used in:
-
The statement
RAISE EXCEPTION -
The
RAISINGaddition for declaring exceptions in [CLASS-] METHODS,FUNCTION, andFORM.
The new statement RESUME is used
to resume the execution of a program after the exception-raising statement, while the resumable exception is being handled.
Modification 2
Keep context of an exception
The context of the exception must be kept during handling to enable the program to be resumed after
handling. To enable this, the new addition BEFORE UNWIND of the statement
CATCH has been introduced. This addition can also be used independently of resumable exceptions.
Modification 3
Repeat the TRY block
The new statement RETRY enables an exception-raising TRY block to be repeated.
