dispose

public void dispose()
             throws DisposeException

Description copied from interface: Disposable

Disposes the component.

Important:
This method is called by an administrating component and must never be called directly.

The implementation should release any resources or objects allocated and any services registered. Furthermore, this method should be developed carefully to free a maximum of resources even when the system may have become unstable. In case of one or multiple errors, you should collect them in a DisposeException, continue with the execution, and throw it at the end of the method.

Note: The implementation must not return before the component is disposed. Any threads or asynchronous calls started must be completed before this method returns.

Specified by:

dispose in interface Disposable

Overrides:

dispose in class AbstractDataManagerPlugIn

Throws:

DisposeException

See Also:

Disposable.dispose()
