Class HeapVerifierImpl

java.lang.Object

com.oracle.svm.core.genscavenge.HeapVerifierImpl

All Implemented Interfaces:

HeapVerifier

public class HeapVerifierImpl
extends Object
implements HeapVerifier

Verification of the heap. This, maybe, could be just an ObjectVisitor, but I want a little more information about where I am, so I'm writing this as a set of recursive-descent methods.
