invertSelection

dispose

public void dispose()

Releases the resources consumed by this EventTableViewer so that it may eventually be garbage collected.

An EventTableViewer will be garbage collected without a call to dispose(), but not before its source EventList is garbage collected. By calling dispose(), you allow the EventTableViewer to be garbage collected before its source EventList. This is necessary for situations where an EventTableViewer is short-lived but its source EventList is long-lived.

Warning: It is an error to call any method on a EventTableViewer after it has been disposed.
