# The FilterIterator class

(PHP 5 >= 5.1.0)

## Introduction

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.

## Class synopsis

abstract FilterIterator extends IteratorIterator implements OuterIterator {
/* Methods */
public abstract bool accept ( void )
public __construct ( Iterator `$iterator` )
public mixed current ( void )
public Iterator getInnerIterator ( void )
public mixed key ( void )
public void next ( void )
public void rewind ( void )
public bool valid ( void )
}
