The RecursiveIterator interface

(PHP 5 >= 5.1.0)

Introdução

Classes implementing RecursiveIterator can be used to iterate over iterators recursively.

RecursiveIterator extends Iterator {

/* Métodos */

public RecursiveIterator getChildren ( void )

public bool hasChildren ( void )

/* Métodos herdados */

abstract public mixed Iterator::current ( void )

abstract public scalar Iterator::key ( void )

abstract public void Iterator::next ( void )

abstract public void Iterator::rewind ( void )

abstract public boolean Iterator::valid ( void )

}

RecursiveIterator::getChildren — Returns an iterator for the current entry.
RecursiveIterator::hasChildren — Returns if an iterator can be created fot the current entry.
