Namespace Cake\Collection\Iterator

Class summary

• BufferedIterator

  Creates an iterator from another iterator that will keep the results of the inner iterator in memory, so that results don't have to be re-calculated.

• ExtractIterator

  Creates an iterator from another iterator that extract the requested column or property based on a path

• FilterIterator

  Creates a filtered iterator from another iterator. The filtering is done by passing a callback function to each of the elements and taking them out if it does not return true.

• InsertIterator

  This iterator will insert values into a property of each of the records returned. The values to be inserted come out of another traversal object. This is useful when you have two separate collections and want to merge them together by placing each of the values from one collection into a property inside the other collection.

• MapReduce

  Implements a simplistic version of the popular Map-Reduce algorithm. Acts like an iterator for the original passed data after each result has been processed, thus offering a transparent wrapper for results coming from any source.

• NestIterator

  A type of collection that is aware of nested items and exposes methods to check or retrieve them

• NoChildrenIterator

  An iterator that can be used as an argument for other iterators that require a RecursiveIterator but do not want children. This iterator will always behave as having no nested items.

• ReplaceIterator

  Creates an iterator from another iterator that will modify each of the values by converting them using a callback function.

• SortIterator

  An iterator that will return the passed items in order. The order is given by the value returned in a callback function that maps each of the elements.

• TreeIterator

  A Recursive iterator used to flatten nested structures and also exposes all Collection methods

• TreePrinter

  Iterator for flattening elements in a tree structure while adding some visual markers for their relative position in the tree

• ZipIterator

  Creates an iterator that returns elements grouped in pairs
