Namespace Cake\Collection\Iterator

Classes summary

• StoppableIterator

  Creates an iterator from another iterator that will verify a condition on each step. If the condition evaluates to false, the iterator will not yield more results.

• ZipIterator

  Creates an iterator that returns elements grouped in pairs

• 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.

• 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.

• 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.

• UnfoldIterator

  An iterator that can be used to generate nested iterators out of a collection of items by applying an function to each of the elements in this iterator.

• ExtractIterator

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

• TreeIterator

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

• NestIterator

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

• ReplaceIterator

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

• InsertIterator

  This iterator will insert values into a property of each of the records returned.

• 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.

• TreePrinter

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

• 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.
