It is invoked after nodes registered with the Observe(Node, IMutationObserverInit) method, are mutated.

Parameters:

callback - The callback.

Method Detail

subscribe

public static com.aspose.ms.System.IDisposable subscribe(Node target,
                                                         MutationCallback callback,
                                                         MutationObserverInit options)

observe

@DOMNameAttribute(name="observe")
public void observe(Node target,
                                                      MutationObserverInit options)

Instructs the user agent to observe a given target (a node) and report any mutations based on the criteria given by options (an object). The options argument allows for setting mutation observation options via object members.

Parameters:

target - The target for observe.

options - The observer options.

disconnect

@DOMNameAttribute(name="disconnect")
public void disconnect()

Stops observer from observing any mutations. Until the observe() method is used again, observer’s callback will not be invoked.

takeRecords

@DOMNameAttribute(name="takeRecords")
public com.aspose.ms.System.Collections.Generic.IGenericEnumerable<MutationRecord> takeRecords()

The method returns a copy of the record queue and then empty the record queue.

Returns:

The copy of the record queue.

invoke

public void invoke()

enqueue

public void enqueue(MutationRecord record)
