Examples of InvalidationListener

javafx.beans.InvalidationListener
org.apache.tapestry.events.InvalidationListener
Interface for objects that may cache information that can be invalidated. @see org.apache.tapestry.events.InvalidationEvent
org.apache.tapestry.internal.events.InvalidationListener
Interface for objects that may cache information that can be invalidated. Invalidation occurs when external files, from which in-memory data is cached, is determined to have changed.
org.apache.tapestry5.internal.events.InvalidationListener
Interface for objects that may cache information that can be invalidated. Invalidation occurs when external files, from which in-memory data is cached, is determined to have changed.
org.apache.tapestry5.services.InvalidationListener
Interface for objects that may cache information that can be invalidated. Invalidation occurs when external files, from which in-memory data is cached, is determined to have changed. Granularity is very limited; when any external file is found to have changed, the event is fired (with the expectation that the cleared cache will be repopulated as necessary). @see org.apache.tapestry5.services.InvalidationEventHub @since 5.1.0.0
