CachingIterator:: (9 methods):
__construct()
count()
current()
key()
next()
rewind()
valid()
exhaustIterator()
storeCurrentItem()
Class: CachingIterator - X-Ref
Iterator for wrapping a Traversable and caching its results.__construct(Traversable $traversable) X-Ref |
Initialize the iterator and stores the first item in the cache. This effectively rewinds the Traversable and the wrapping IteratorIterator. Additionally, this mimics behavior of the SPL iterators and allows users to omit an explicit call * to rewind() before using the other methods. param: Traversable $traversable |
count() X-Ref |
return: integer |
current() X-Ref |

key() X-Ref |

valid() X-Ref |

exhaustIterator() X-Ref |
Ensures that the inner iterator is fully consumed and cached. |
storeCurrentItem() X-Ref |
Stores the current item in the cache. |
