Class ObjectSizer

java.lang.Object

com.pivotal.gemfirexd.tools.sizer.ObjectSizer

public class ObjectSizer
extends Object

This class helps in finding out memory footprint per Region and divides memory usage between GemFireXD, GemFire and java usages.

Optionally, it prints class inclusion sequence much like stack trace and per member memory.

Indexes are accounted separately than regions.
