Method Detail

delete

void delete()
      throws java.io.IOException

Delete all the calls to sandmark.watermark.ct.trace.Annotator.sm$mark(*) in every class in the program. This is the main entry point to this class.

java.io.IOException

deleteMarkCalls

boolean deleteMarkCalls(EditedClass ec)

Delete all the calls to sandmark.watermark.ct.trace.Annotator.sm$mark(*) in every method in the given class.

Parameters:

ec - the class to be edited Return 'true' if the class was changed.

deleteMarkCalls

boolean deleteMarkCalls(EditedClass ec,
                        de.fub.bytecode.generic.MethodGen mg)

Delete every call to sandmark.watermark.ct.trace.Annotator.sm$mark(*) in the given method. Return 'true' if the method was changed.

Parameters:

ec - the class to be edited

mg - the method to be edited

deleteMarkCall

boolean deleteMarkCall(EditedClass ec,
                       de.fub.bytecode.generic.MethodGen mg,
                       de.fub.bytecode.generic.INVOKESTATIC call,
                       de.fub.bytecode.generic.InstructionHandle ih)

Check if the given instruction is a call to sandmark.watermark.ct.trace.Annotator.sm$mark(*) If it is, replace it with a "NOP". This way we don't have to worry about jumps to the removed instructions. The NOPs should be removed later. "sm$mark(String)" and "sm$mark(long)" are instead replaced by "POP". Ideally, we'd like to delete them too, but that is hard. Consider, for example, "sm$mark(k+x*4)".

Parameters:

ec - the class to be edited

mg - the method to be edited

call - the call instruction to be deleted

ih - the instruction handle of the call instruction Return 'true' if the method was changed.

main

public static void main(java.lang.String[] args)
