Method Summary

Modifier and TypeMethod and Description
pack-priv static ThreadGroupReference
find(String name)

public boolean
hasNext()

Implements java.util.Iterator.hasNext.

Returns true if the iteration has more elements.

public ThreadGroupReference
next()

Implements java.util.Iterator.next.

Returns the next element in the iteration.

public ThreadGroupReference
nextThreadGroup()

private void
push(List<ThreadGroupReference> tgl)

The invariant in this class is that the top iterator on the stack has more elements.

public void
remove()

Overrides default java.util.Iterator.remove.

Removes from the underlying collection the last element returned by this iterator (optional operation).

public boolean hasNext()

Implements java.util.Iterator.hasNext.

Doc from java.util.Iterator.hasNext.

Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)

private void push(List<ThreadGroupReference> tgl)

The invariant in this class is that the top iterator on the stack has more elements. If the stack is empty, there is no top. This method assures this invariant.

removeback to summary
public void remove()

Overrides default java.util.Iterator.remove.

Doc from java.util.Iterator.remove.

Removes from the underlying collection the last element returned by this iterator (optional operation). This method can be called only once per call to next.

The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method, unless an overriding class has specified a concurrent modification policy.

The behavior of an iterator is unspecified if this method is called after a call to the forEachRemaining method.
