Method Detail

dispose

public void dispose()

Description copied from interface: NamedBean

Deactivate this object, so that it releases as many resources as possible and no longer effects others.

For example, if this object has listeners, after a call to this method it should no longer notify those listeners. Any native or system-wide resources it maintains should be released, including threads, files, etc.

It is an error to invoke any other methods on this object once dispose() has been called. Note, however, that there is no guarantee about behavior in that case.

Afterwards, references to this object may still exist elsewhere, preventing its garbage collection. But it's formally dead, and shouldn't be keeping any other objects alive. Therefore, this method should null out any references to other objects that this NamedBean contained.

dispose in class AbstractNamedBean

requestUpdateFromLayout

public void requestUpdateFromLayout()

Request an update on status.

Since status is continually being updated, this isn't active now. Eventually, we may want to have this move the related AIU to the top of the polling queue.
