DESCRIPTION

12       mprof-heap-viewer GUI viewer for the logging profiler heap snapshots
13
14       WARNING: this application is unfinished and experimental.  Nevertheless
15       it should work, and bug reports are encouraged.
16
17       This program decodes the contents of a logging profiler output file and
18       locates  all  the  heap  snapshots inside it.  The user can then select
19       each individual snapshot and decide to load it in  memory  and  explore
20       its contents.
21
22       The GUI is organized to work on "object sets" (listed in a tree view on
23       the left).  All operations are performed  with  a  popup  menu  on  the
24       choosen set.
25
26       Initially  the  sets  are the heap snapshots (of course a heap snapshot
27       can be considered a set of objects!).  For each set the  GUI  shows  on
28       the right a list that breaks it down by class (one row for each class).
29
30       The user can then refine each set using a "filter", to select a subset.
31       Examples of filters are "all objects of class X", or "all objects  that
32       reference  an  object of class X".  This way the user explores the sets
33       breaking them down to subsets (each subset in the GUI is a child of its
34       owner set on the tree view).
35
36       Moreover the user can issue a "compare" operation between two arbitrary
37       sets A and B, which will compute two subsets: "A - B" (the objects of A
38       which  are  not  in B, a subsect of A) and "B - A" (the reverse).  This
39       can help in understanding what changed on the heap between garbage col‐
40       lections.
