The MultipleIterator class

Introduction

An Iterator that iterates over several iterators one after the other.

MultipleIterator implements Iterator , Traversable {

/* Constants */

const integer MultipleIterator::MIT_NEED_ANY = 0 ;

const integer MultipleIterator::MIT_NEED_ALL = 1 ;

const integer MultipleIterator::MIT_KEYS_NUMERIC = 0 ;

const integer MultipleIterator::MIT_KEYS_ASSOC = 2 ;

/* Methods */

public void attachIterator ( Iterator $iterator [, string $infos ] )

__construct ( integer $flags )

public void containsIterator ( Iterator $iterator )

public void countIterators ( void )

public void current ( void )

public void detachIterator ( Iterator $iterator )

public void getFlags ( void )

public void key ( void )

public void next ( void )

public void rewind ( void )

public void setFlags ( integer $flags )

public void valid ( void )

}

MultipleIterator::MIT_NEED_ANY: Do not require all sub iterators to be valid in iteration.
MultipleIterator::MIT_NEED_ALL: Require all sub iterators to be valid in iteration.
MultipleIterator::MIT_KEYS_NUMERIC: Keys are created from the sub iterators position.
MultipleIterator::MIT_KEYS_ASSOC: Keys are created from sub iterators associated information.

MultipleIterator::attachIterator — Attaches iterator information
MultipleIterator::__construct — Constructs a new MultipleIterator
MultipleIterator::containsIterator — Checks if an iterator is attached
MultipleIterator::countIterators — Gets the number of attached iterator instances
MultipleIterator::current — Gets the registered iterator instances
MultipleIterator::detachIterator — Detaches an iterator
MultipleIterator::getFlags — Gets the flag information
MultipleIterator::key — Gets the registered iterator instances
MultipleIterator::next — Moves all attached iterator instances forward
MultipleIterator::rewind — Rewinds all attached iterator instances
MultipleIterator::setFlags — Sets flags
MultipleIterator::valid — Checks the validity of sub iterators
