HPROF Enhancement

Identifier:

org.eclipse.mat.hprof.enhancer

Since:

0.7.0

Description:

This extension point can be used to provide more details about the heap dump which are not contained in the HPROF format itself. For example, SAP has extended the Hotspot-based SAPJVM to write perm space information, OoM stack traces, interfaces and object generations whenever a HPROF dump is written.
