Constructor Details

GCSegmentIterator

protected GCSegmentIterator(com.ibm.j9ddr.vm29.pointer.generated.J9MemorySegmentListPointer list,
 long flags)
                     throws CorruptDataException

Throws:

CorruptDataException

Method Details

fromJ9MemorySegmentList

public static GCSegmentIterator fromJ9MemorySegmentList(com.ibm.j9ddr.vm29.pointer.generated.J9MemorySegmentListPointer list,
 long flags)
                                                 throws CorruptDataException

Factory method to construct an appropriate segment iterator.

Parameters:

list - the J9MemorySegmentList to iterate

flags - only iterate segments that match these flags

Returns:

an instance of GCSegmentIterator

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.J9MemorySegmentPointer 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()
