Method Details

from

public static GCVMThreadListIterator from()
                                   throws CorruptDataException

Factory method to construct an appropriate vm thread list iterator.

Type Parameters:

T -

Parameters:

structure - the J9JavaVM

Returns:

an instance of GCVMThreadListIterator

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.J9VMThreadPointer 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()
