- true if it is OK for detach to release this iterator
for pooling.public void detach()
DTMIterator
from the set which it iterated
over, releasing any computational resources and placing the iterator
in the INVALID state. After detach
has been invoked,
calls to nextNode
or previousNode
will
raise a runtime exception.
In general, detach should only be called once on the object.
