Constructor Details

GCClassHeapIterator

protected GCClassHeapIterator(com.ibm.j9ddr.vm29.pointer.generated.J9MemorySegmentPointer memorySegment)
                       throws CorruptDataException

Throws:

CorruptDataException

Method Details

fromJ9MemorySegment

public static GCClassHeapIterator fromJ9MemorySegment(com.ibm.j9ddr.vm29.pointer.generated.J9MemorySegmentPointer memorySegment)
                                               throws CorruptDataException

Factory method to construct an appropriate class segment iterator.

Parameters:

memorySegment - the memorySegment to iterate

Returns:

an instance of GCClassHeapIterator

Throws:

CorruptDataException

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.)

Returns:

true if the iteration has more elements

next

public com.ibm.j9ddr.vm29.pointer.generated.J9ClassPointer next()

Description copied from interface: java.util.Iterator

Returns the next element in the iteration.

Returns:

the next element in the iteration

nextAddress

public VoidPointer nextAddress()
