These object graphs are difficult to design correctly and even more difficult to debug if incorrect. Unfortunately, very subtle bugs in object-oriented programs are directly caused by object graph topologies. Snapshot query-based debuggers let programmers examine object graph snapshots of programs in detail using a specially designed query language. This provides users with an ability to debug and examine their programs in great detail at the time when the memory snapshot is taken.pdfen-NZCopyright 2004 IEEE.
