The FilterIterator class

简介

This abstract iterator filters out unwanted values. This class should be extended to implement custom iterator filters. The FilterIterator::accept() must be implemented in the subclass.

abstract FilterIterator extends IteratorIterator implements OuterIterator , Traversable , Iterator {

/* 方法 */

abstract bool accept ( void )

}

FilterIterator::accept — Check whether the current element of the iterator is acceptable
FilterIterator::__construct — Construct a filterIterator
FilterIterator::current — Get the current element value
FilterIterator::getInnerIterator — Get the inner iterator
FilterIterator::key — Get the current key
FilterIterator::next — Move the iterator forward
FilterIterator::rewind — Rewind the iterator
FilterIterator::valid — Check whether the current element is valid
