The CachingIterator class

Introduction

This object supports cached iteration over another iterator.

CachingIterator extends IteratorIterator implements OuterIterator , Traversable , Iterator , ArrayAccess , Countable {

/* Constants */

const integer CALL_TOSTRING = 1 ;

const integer CATCH_GET_CHILD = 16 ;

const integer TOSTRING_USE_KEY = 2 ;

const integer TOSTRING_USE_CURRENT = 4 ;

const integer TOSTRING_USE_INNER = 8 ;

const integer FULL_CACHE = 256 ;

/* Methods */

}

CachingIterator::__construct - Construct a new CachingIterator object for the iterator.
CachingIterator::count - The number of elements in the iterator
CachingIterator::current - Return the current element
CachingIterator::getCache - The getCache purpose
CachingIterator::getFlags - Get flags used
CachingIterator::getInnerIterator - Returns the inner iterator
CachingIterator::hasNext - Check whether the inner iterator has a valid next element
CachingIterator::key - Return the key for the current element
CachingIterator::next - Move the iterator forward
CachingIterator::offsetExists - The offsetExists purpose
CachingIterator::offsetGet - The offsetGet purpose
CachingIterator::offsetSet - The offsetSet purpose
CachingIterator::offsetUnset - The offsetUnset purpose
CachingIterator::rewind - Rewind the iterator
CachingIterator::setFlags - The setFlags purpose
CachingIterator::__toString - Return the string representation of the current element
CachingIterator::valid - Check whether the current element is valid
