The ActionScript extension class can dispose of the ExtensionContext
instance by calling the ExtensionContext method
dispose()
.
This method notifies the native implementation to clean up resources
that the instance uses. For example, the TVChannelController class
can add a method for cleaning up:
public function dispose (): void {
extContext.dispose();
// Clean up other resources that the TVChannelController instance uses.
}
Your ActionScript extension class does not have to explicitly
call the ExtensionContext instance’s
dispose()
method.
In this case, the runtime calls it when the runtime garbage collector
disposes of the ExtensionContext instance. A best practice, however,
is to explicitly call
dispose()
. An explicit call
to
dispose()
typically cleans up resources much
sooner than waiting for the garbage collector.
Whether called explicitly or by the garbage collector, the ExtensionContext
dispose()
method
results in a call to the native implementation’s context finalizer.
