Constructor Details

HeapObjectIterator

public HeapObjectIterator(DTFJJavaHeap heap,
 GCHeapRegionDescriptor region)
                   throws CorruptDataException

Throws:

CorruptDataException

Method Details

hasNext

public boolean hasNext()

Description copied from interface: java.util.Iterator

Returns true if the iteration has more elements. (In other words, returns true if Iterator.next() would return an element rather than throwing an exception.)

Specified by:

hasNext in interface Iterator

Returns:

true if the iteration has more elements

doDeadObject

public void doDeadObject(com.ibm.j9ddr.vm29.pointer.generated.J9ObjectPointer object)

Specified by:

doDeadObject in interface HeapWalkerEvents

doLiveObject

public void doLiveObject(com.ibm.j9ddr.vm29.pointer.generated.J9ObjectPointer ptr)

Specified by:

doLiveObject in interface HeapWalkerEvents

doSectionEnd

public void doSectionEnd(long address)

Specified by:

doSectionEnd in interface HeapWalkerEvents

doSectionStart

public void doSectionStart(long address)

Specified by:

doSectionStart in interface HeapWalkerEvents

next

public Object next()

Description copied from interface: java.util.Iterator

Returns the next element in the iteration.

Specified by:

next in interface Iterator

Returns:

the next element in the iteration

doCorruptData
