Constructor & Destructor Documentation

rsb::patterns::RemoteServer::RemoteServer	(	const Scope &	scope,
		const ParticipantConfig &	listenerConfig,
		const ParticipantConfig &	informerConfig
	)

Construct a new RemoteServer object which can be used to call methods of the server at scope.

Parameters

scope The base scope of the server the methods of which will be called.

Member Function Documentation

EventPtr rsb::patterns::RemoteServer::call	(	const std::string &	methodName,
		EventPtr	data,
		unsigned int	maxReplyWaitTime = `25`
	)

Call the method named methodName on the remote server, passing it the event data as argument and returning an event which contains the value returned by the remote method.

This method blocks until the computation on the remote side has been completed and the result has been received.

Parameters

methodName	Name of the method that should be called.
data	An Event object containing the argument object that should be passed to the called method.
maxReplyWaitTime	Maximum number of seconds to wait for a reply from the server when calling a method.

Returns: An Event object containing the result of the method call.

Exceptions

rsc::threading::FutureTimeoutException	if the method call is not completed within the maximum waiting time.
rsc::threading::FutureTaskExecutionException	if the method call fails.

Definition at line 197 of file RemoteServer.cpp.

	)

inline

Call the method named methodName on the remote server, passing it the argument object args and return the value returned by the remote method.

This method blocks until the computation on the remote side has been completed and the result has been received.

Template Parameters

I	type of the method call argument object.
O	type of the method return value.

Parameters

methodName	Name of the method that should be called.
args	The argument object that should be passed to the called method.
maxReplyWaitTime	Maximum number of seconds to wait for a reply from the server when calling a method.

Returns: The result of the method call.

Exceptions

rsc::threading::FutureTimeoutException	if the method call is not completed within the maximum waiting time.
rsc::threading::FutureTaskExecutionException	if the method call fails.

inline

Call the method named methodName on the remote server, without arguments and return the value returned by the remote method.

This method blocks until the computation on the remote side has been completed and the result has been received.

Template Parameters

O	type of the method return value.

Parameters

methodName	Name of the method that should be called.
maxReplyWaitTime	Maximum number of seconds to wait for a reply from the server when calling a method.

RemoteServer::FuturePtr rsb::patterns::RemoteServer::callAsync	(	const std::string &	methodName,
		EventPtr	data
	)

Call the method named methodName on the remote server, passing it the event data as argument and returning an event which contains the value returned by the remote method.

Parameters

methodName	Name of the method that should be called.
data	An Event object containing the argument object that should be passed to the called method.

Returns: A rsc::threading::TimeoutFuture object from which the result (an EventPtr) of the method call can be obtained at the caller's discretion.
