        namespace="<global>",
        name="MessagePort")
public class MessagePort
extends EventTarget
implements MessageEventSource, Transferable

The MessagePort interface of the Channel Messaging API represents one of the two ports of a MessageChannel, allowing messages to be sent from one port and listening out for them arriving at the other.

Field Detail

onmessage

@Nullable
public MessageEventHandler onmessage

The onmessage event handler of the MessagePort interface is an EventListener, called whenever an MessageEvent of type message is fired on the port — that is, when the port receives a message.

onmessageerror

@Nullable
public MessageEventHandler onmessageerror

The onmessageerror event handler of the MessagePort interface is an EventListener, called whenever an MessageEvent of type messageerror is fired on the port—that is, when it receives a message that cannot be deserialized.

Method Detail

close

public void close()

The close() method of the MessagePort interface disconnects the port, so it is no longer active. This stops the flow of messages to that port.

MessagePort.close - MDN, close() - HTML Living Standard

postMessage

public void postMessage(@Nullable
                        java.lang.Object message,
                        @Nonnull
                        JsArray<Transferable> transfer)

The postMessage() method of the MessagePort interface sends a message from the port, and optionally, transfers ownership of objects to other browsing contexts.

See Also:

MessagePort.postMessage - MDN, postMessage() - HTML Living Standard

postMessage

public void postMessage(@Nullable
                        java.lang.Object message,
                        @Nonnull
                        Transferable[] transfer)

The postMessage() method of the MessagePort interface sends a message from the port, and optionally, transfers ownership of objects to other browsing contexts.

See Also:

MessagePort.postMessage - MDN, postMessage() - HTML Living Standard

postMessage

public void postMessage(@Nullable
                        java.lang.Object message,
                        @Nonnull
                        PostMessageOptions options)

The postMessage() method of the MessagePort interface sends a message from the port, and optionally, transfers ownership of objects to other browsing contexts.

MessagePort.postMessage - MDN, postMessage() - HTML Living Standard

postMessage

public void postMessage(@Nullable
                        java.lang.Object message)

The postMessage() method of the MessagePort interface sends a message from the port, and optionally, transfers ownership of objects to other browsing contexts.

See Also:

MessagePort.postMessage - MDN, postMessage() - HTML Living Standard

start

public void start()

The start() method of the MessagePort interface starts the sending of messages queued on the port. This method is only needed when using EventTarget.addEventListener; it is implied when using MessageChannel.onmessage.
