Detailed Description

Network protocol endpoint.

Contains:

object address <-> object name mapping
message handler registration and message dispatching

Member Function Documentation

void GammaRay::Endpoint::disconnected ( )

signal

Emitted when we lost the connection to the other endpoint.

void GammaRay::Endpoint::dispatchMessage ( const GammaRay::Message & msg )

protected

Calls the message handler registered for the receiver of msg.

Protocol::ObjectAddress GammaRay::Endpoint::endpointAddress ( ) const

protected

The object address of the other endpoint.

virtual void GammaRay::Endpoint::handlerDestroyed	(	Protocol::ObjectAddress	objectAddress,
		const QString &	objectName
	)

protectedpure virtual

Called when the current handler of the object identified by objectAddress has been destroyed.

static Endpoint* GammaRay::Endpoint::instance ( )

static

Singleton accessor.

virtual void GammaRay::Endpoint::invokeObject	(	const QString &	objectName,
		const char *	method,
		const QVariantList &	args = `QVariantList()`
	)		const

virtual

Invoke method on the object called objectName with the given args.

This also works with signals.

The default implementation forwards the object calls to remote side when the endpoint is connected. The Server implementation is furthermore expected to call the method directly on the local object to support the in-process mode.

void GammaRay::Endpoint::invokeObjectLocal	(	QObject *	object,
		const char *	method,
		const QVariantList &	args
	)		const

protected

Invoke method on object with the given args.

This is invokes the method directly on the local object.

static bool GammaRay::Endpoint::isConnected ( )

static

Returns true if we are currently connected to another endpoint.

virtual bool GammaRay::Endpoint::isRemoteClient ( ) const

pure virtual

Returns true for remote clients and false for the in-probe server endpoint.

QString GammaRay::Endpoint::label ( ) const

Returns a human-readable string describing the host program.

virtual void GammaRay::Endpoint::messageReceived ( const Message & msg )

protectedpure virtual

Called for every incoming message.

See Also: dispatchMessage().

Protocol::ObjectAddress GammaRay::Endpoint::objectAddress ( const QString & objectName ) const

Returns the object address for objectName, or Protocol::InvalidObjectAddress if not known.

QVector<QPair<Protocol::ObjectAddress, QString> > GammaRay::Endpoint::objectAddresses ( ) const

protected

All current object name/address pairs.

virtual void GammaRay::Endpoint::objectDestroyed	(	Protocol::ObjectAddress	objectAddress,
		const QString &	objectName,
		QObject *	object
	)

protectedpure virtual

Called when a registered object identified by objectAddress has been destroyed.

void GammaRay::Endpoint::objectRegistered	(	const QString &	objectName,
		Protocol::ObjectAddress	objectAddress
	)

signal

Emitted when a new object with name objectName has been registered at address objectAddress.

void GammaRay::Endpoint::registerMessageHandlerInternal	(	Protocol::ObjectAddress	objectAddress,
		QObject *	receiver,
		const char *	messageHandlerName
	)

protected

Register the slot messageHandlerName on receiver as the handler for messages to/from objectAddress.

See Also: dispatchMessage()

virtual Protocol::ObjectAddress GammaRay::Endpoint::registerObject	(	const QString &	name,
		QObject *	object
	)

virtual

Register an object of the given name for transparent server/client communication.

void GammaRay::Endpoint::registerObjectInternal	(	const QString &	objectName,
		Protocol::ObjectAddress	objectAddress
	)

protected

Call this when learning about a new object <-> address mapping.

static void GammaRay::Endpoint::send ( const Message & msg )

static

Send msg to the connected endpoint.

virtual QString GammaRay::Endpoint::serverAddress ( ) const

pure virtual

Returns the address of the server, in case you need to connect to a different service there (such as the web inspector server).

void GammaRay::Endpoint::setDevice ( QIODevice * device )

protected

Call with the socket once you have established a connection to another endpoint, takes ownership of device.

void GammaRay::Endpoint::setLabel ( const QString & label )

Sets the human-readable label of this instance used e.g. when advertising on the network.

void GammaRay::Endpoint::unregisterMessageHandlerInternal ( Protocol::ObjectAddress objectAddress )

protected

Unregister the message handler for objectAddress.

void GammaRay::Endpoint::unregisterObjectInternal ( const QString & objectName )

protected

Call this when learning about a dissolved object <-> address mapping.

void GammaRay::Endpoint::waitForMessagesWritten ( )

Write all pending data and block until this is done.

This should only be used in very rare situations.
