Method Details

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 iterate

region - 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

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.MM_HeapRegionDescriptorPointer 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()
