`Chain Of Responsibilities`__
2+
=============================
3+
4+
Purpose:
5+
--------
6+
7+
To build a chain of objects to handle a call in sequential order. If one
8+
object cannot handle a call, it delegates the call to the next in the
9+
chain and so forth.
10+
11+
Examples:
12+
---------
13+
14+
- logging framework, where each chain element decides autonomously what
15+
to do with a log message
16+
- a Spam filter
17+
- Caching: first object is an instance of e.g. a Memcached Interface,
18+
if that "misses" it delegates the call to the database interface
19+
- Yii Framework: CFilterChain is a chain of controller action filters.
20+
the executing point is passed from one filter to the next along the
21+
chain, and only if all filters say "yes", the action can be invoked
22+
at last.
