FilterIterator 類

(PHP 5 >= 5.1.0, PHP 7, PHP 8)

簡介

這個抽象類的遍歷并過濾出不想要的值。這個類應(yīng)該被實現(xiàn)了迭代過濾器的類繼承 FilterIterator::accept() 方法必須被子類實現(xiàn)。

abstract class FilterIterator extends IteratorIterator {

/* 方法 */

public __construct(Iterator $iterator)

/* 繼承的方法 */

}

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
