The Yaf_Application class

(Yaf >=1.0.0)

Introduction

Yaf_Application provides a bootstrapping facility for applications which provides reusable resources, common- and module-based bootstrap classes and dependency checking.

Note:
Yaf_Application implements the singleton pattern, and Yaf_Application can not be serialized or unserialized, which will cause problems when you try to use PHPUnit to write some test cases for Yaf.

You may use the @backupGlobals annotation of PHPUnit to control the backup and restore operations for global variables, thus solving this problem.
