Method Detail

getInitializedContextManager

private static ContextManager getInitializedContextManager(org.apache.avalon.framework.context.Context initParameters,
                                                           org.apache.avalon.framework.logger.Logger logger)

Initialize the ContainerManager

Specified by:

initialize in interface org.apache.avalon.framework.activity.Initializable

Throws:

disposeContainer

protected void disposeContainer()

dispose

public void dispose()

Dispose of the ContainerManager and managed Container

Specified by:

dispose in interface org.apache.avalon.framework.activity.Disposable

getContainer

public java.lang.Object getContainer()

Get a reference to your Container. Typically, you would cast this to whatever interface you will use to interact with it.

Specified by:

getContainer in interface org.apache.avalon.fortress.ContainerManager

getLogger

public final org.apache.avalon.framework.logger.Logger getLogger()

Allows to get the logger and associated hierarchy for logging.
