There is no work underway in the SDK
that corresponds to this. We had once thought about having a "snapshot
and compare" facility in the variables view, but never had the resources
to implement it.

[jdt-debug-dev] JHat integration with
JDT debugger planned?
Hello
I am considering implementing something like JHat's object query
facility within the Eclipse debugger. Does anyone know if there is
already work under way on something like it? I am aware of "Show all
instances" and "..references", but my idea is different:
The idea is to have a view which is similar to a watch window, but
runs an object query whenever the debugger breaks. The query result is
shown with differences to the previous result highlighted (I am also
thinking of offering a diff view for any two such snapshots). This
would, I believe, be great for monitoring relevant excerpts of
complex, nested data structures at a glance while stepping through
code. For example:
name; children{ name; children< }
would allow one to keep an eye on the full expansion of a recursive
tree of objects, where for every object just the name field is listed.
Queries could be rooted at a particular object selected within the
debugger, or else global across all instances in the heap.

Any pointers to existing work or ideas would be appreciated.
