Creates a new RespondingChannel wrapping a single MessageChannel.

extends goog.Disposable
Instance Method Summary
callbackProxy_(function ((Object|string)): ? callback, !Object message)

A intermediary proxy for service callbacks to be invoked and return their their results to the remote caller's callback.

callbackServiceHandler_(?Object message)

Receives the results of the peer's service results.

disposeInternal()

Deletes or nulls out any references to COM objects, DOM nodes, or other disposable objects. Classes that extend {@code goog.Disposable} should override this method. Not reentrant. To avoid calling it twice, it must only be called from the subclass' {@code disposeInternal} method. Everywhere else the public {@code dispose} method must be used. For example: 

mypackage.MyClass = function() {
goog.base(this);
// Constructor logic specific to MyClass.
...
};
goog.inherits(mypackage.MyClass, goog.Disposable);

mypackage.MyClass.prototype.disposeInternal = function() {
goog.base(this, 'disposeInternal');
// Dispose logic specific to MyClass.
...
};

getNextSignature_() ⇒ number

Gets a random number to use for method invocation results.

registerService(string serviceName, function (Object): ? callback)

Registers a service to be called when a message is received.

send(string serviceName, (Object|string) payload, function ((Object|null)): ? callback)

Sends a message over the channel.
