fromMMHeapRegionDescriptor
public static GCHeapSpanRegionIterator fromMMHeapRegionDescriptor(com.ibm.j9ddr.vm29.pointer.generated.MM_HeapRegionManagerPointer manager, com.ibm.j9ddr.vm29.pointer.generated.MM_HeapRegionDescriptorPointer region) throws CorruptDataException Factory method to construct an appropriate segment iterator.- Parameters:
manager
- the MM_HeapRegionManagerPointer to iterateregion
- the MM_HeapRegionDescriptorPointer representing the spanning region- Returns:
- an instance of GCHeapSpanRegionIterator
- Throws:
CorruptDataException
-
hasNext
public boolean hasNext()Description copied from interface:java.util.Iterator
Returnstrue
if the iteration has more elements. (In other words, returnstrue
ifIterator.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.MM_HeapRegionDescriptorPointer next()Description copied from interface:java.util.Iterator
Returns the next element in the iteration.- Returns:
- the next element in the iteration
