I want to write a program (preferably in java) that will parse and analyze a java heap dump file (created by jmap). I know there are many great tools that already do so (jhat, eclipse's MAT, and so on), but I want to analyze the heap from a specific perspective to my application.
Where can I read about the structure of the heap dump file, examples how to read it, and so on? Didn't find anything useful searching for it...
Many thanks.
I'm not familiar with jhat, but Eclipse's MAT is open source. Their SVN link is available, perhaps you could look through that for their parser, perhaps even use it.
