The ParentIterator class

(PHP 5 >= 5.1.0, PHP 7)

Introducere

This extended FilterIterator allows a recursive iteration using RecursiveIteratorIterator that only shows those elements which have children.

ParentIterator extends RecursiveFilterIterator implements RecursiveIterator , OuterIterator {

/* Metode */

public bool accept ( void )

public __construct ( RecursiveIterator $iterator )

public ParentIterator getChildren ( void )

public bool hasChildren ( void )

public void next ( void )

public void rewind ( void )

}

ParentIterator::accept — Determines acceptability
ParentIterator::__construct — Constructs a ParentIterator
ParentIterator::getChildren — Return the inner iterator's children contained in a ParentIterator
ParentIterator::hasChildren — Check whether the inner iterator's current element has children
ParentIterator::next — Move the iterator forward
ParentIterator::rewind — Rewind the iterator
