/**
|
|
|
|
* Container is a dependency injection container.
|
|
|
|
*
|
2010-06-27 17:28:29 +01:00
|
|
|
* It gives access to object instances (services).
|
2010-01-04 14:26:20 +00:00
|
|
|
*
|
|
|
|
* Services and parameters are simple key/pair stores.
|
|
|
|
*
|
2011-01-03 08:07:06 +00:00
|
|
|
* Parameter and service keys are case insensitive.
|
2010-01-04 14:26:20 +00:00
|
|
|
*
|
|
|
|
* A service id can contain lowercased letters, digits, underscores, and dots.
|
|
|
|
* Underscores are used to separate words, and dots to group services
|
|
|
|
* under namespaces:
|
|
|
|
*
|
|
|
|
* <ul>
|
|
|
|
* <li>request</li>
|
|
|
|
* <li>mysql_session_storage</li>
|
|
|
|
* <li>symfony.mysql_session_storage</li>
|
|
|
|
* </ul>
|
|
|
|
*
|
|
|
|
* A service can also be defined by creating a method named
|
|
|
|
* getXXXService(), where XXX is the camelized version of the id:
|
|
|
|
*
|
|
|
|
* <ul>
|
|
|
|
* <li>request -> getRequestService()</li>
|
|
|
|
* <li>mysql_session_storage -> getMysqlSessionStorageService()</li>
|
|
|
|
* <li>symfony.mysql_session_storage -> getSymfony_MysqlSessionStorageService()</li>
|
|
|
|
* </ul>
|
|
|
|
*
|
|
|
|
* The container can have three possible behaviors when a service does not exist:
|
|
|
|
*
|
|
|
|
* * EXCEPTION_ON_INVALID_REFERENCE: Throws an exception (the default)
|
|
|
|
* * NULL_ON_INVALID_REFERENCE: Returns null
|
|
|
|
* * IGNORE_ON_INVALID_REFERENCE: Ignores the wrapping command asking for the reference
|
|
|
|
* (for instance, ignore a setter if the service does not exist)
