A BackingMap plug-in implements the BackingMapPlugin mix-in interface, which you can use to receive extended capabilities for managing its life cycle.
Any existing BackingMap plug-in that also implements the BackingMapPlugin interface will automatically receive the extended set of lifecycle events during its construction and use.
The BackingMapPlugin interface provides methods to set or modify the state of the plug-in, as well as methods to introspect the current state of the plug-in.
All methods must be implemented correctly, and the WebSphere® eXtreme Scale runtime environment verifies the method behavior under certain circumstances. For example, after calling the initialize() method, the eXtreme Scale runtime environment calls the isInitialized() method to ensure that the method successfully completed the appropriate initialization.
