[jdt-debug-dev] Modification Watchpoint

[Ralf Anklam <ikeman@xxxxxxxxxxxxxxx>]

Hello,

programmatically I create a modification watchpoint on a field and if 
the field is modified, I get noticed.
I want to readout and store the value of this field. To do this I 
implemented the IDebugEventSetListenerInterface
and react on suspend events, which are initiated by my watchpoint 
(IJavaBreakpointListener.breakpointHit()).
If I want to readout the value, I get the old value and not the value, 
which will be set.

The JDI offers a ModificationWatchpointEvent and the opportunity the 
readout the value (ModificationWatchpointEvent.valueToBe())
Unfortunately this is not an org.eclipse.debug.core.DebugEvent, so I can 
not react in the IDebugEventSetListener.handleDebugEvents().

To react on this Event I would build a subclass of 
org.eclipse.jdt.internal.debug.core.breakpoints.JavaWatchpoint
and overwrite the method handleEvent() to handle the 
ModificationWatchpointEvent. So I would be able to store the value of my 
field.

Is this procedure the right way? Or is there some smarter solution to 
get the value after modification?
