`Composite`__
|
|
=============
|
|
|
|
Purpose
|
|
-------
|
|
|
|
To treat a group of objects the same way as a single instance of the
|
|
object.
|
|
|
|
Examples
|
|
--------
|
|
|
|
- a form class instance handles all its form elements like a single
|
|
instance of the form, when ``render()`` is called, it subsequently
|
|
runs through all its child elements and calls ``render()`` on them
|
|
- ``Zend_Config``: a tree of configuration options, each one is a
|
|
``Zend_Config`` object itself
