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.)

Returns:

true if the iteration has more elements

nextAddress

public VoidPointer nextAddress()

next

public com.ibm.j9ddr.vm29.pointer.generated.J9ObjectPointer next()

Description copied from interface: java.util.Iterator

Returns the next element in the iteration.

Returns:

the next element in the iteration
