Constructor Detail

BooleanAbstractIterator

public BooleanAbstractIterator()

get

public Object get()

Description copied from interface: IndefiniteIterator

Return the current element in this iteration. This method may be called multiple times, and does not advance the state of the iterator when it is called. The idea is to permit several similar copies to be returned (e.g., clones) each time it is called.
