FilterIterator<A,B>
extends UnmodifiableIterator<B>
A
FilterIterator filters and maps a source
Iterator to generate a new one.
Note that this implementation reads one element ahead, so if the
Filter changes for an object 'o' between the time that is read
(when next() is called, returning the object preceding 'o', and
checking that 'o' satisfies the current Filter) and the time when
hasNext() is called, 'o' will still be returned, regardless of what
Filter.isElement(o) returns. Thus, it is recommended that only
Filters which remain consistent throughout the iteration be used.
