Detailed Description

ALProxy is a client to the served methods of a module.

It gives access to the methods of a module without needing to know if the module that provides a service is in the same process, on the same machine, or on the same tcp network.

ALProxy is a generic client in that it can be constructed using just the name of the module that you wish to connect to. Once connected, methods are availble via templated calls. While generic and flexible, these provide no checking on the availabilty or signature of a method until runtime.

All Aldebaran provided modules have classes called 'specific' proxies built around this generic proxy. When using a specific proxy, explicit method signatures are provided which allows correctness to be validated at runtime. In addition, specific proxies include optimisations for local calls that are easily available in the generic proxy. e.g. #include <alproxies/altexttospeechproxy> ... AL::ALTextToSpeechProxy tts; tts.say("hello world");

Member Function Documentation

AL::ALValue AL::ALProxy::genericCall	(	const std::string &	strMethodName,
		const AL::ALValue &	listParams
	)

A generic call, without type optimisation, using AL::ALValue for each call... (local or not).

Used from a C++ code not knowing the signature of the called method

Parameters:

strMethodName	the name of the method to call
listParams	the list of parameters (possibly no params)

Returns:: an alvalue, possibly invalid if function returns nothing

int AL::ALProxy::genericPCall	(	const std::string &	strMethodName,
		const AL::ALValue &	listParams,
		onFinishedCallback	pCallbackToCallOnFinished = `NULL`,
		const char *	pszCallerName = `NULL`
	)

A generic post-call, without type optimisation, using AL::ALValue for each call... (local or not).

Used from a C++ code not knowing the signature of the called method

Warning:: the callback will still be called if the proxy is destroyed.

Parameters:

strMethodName	the name of the method to call
listParams	the list of parameters (possibly no params)
pCallbackToCallOnFinished	a callback to call when task is finished (NULL if no callback) DEPRECATED
pszCallerName	the name of the caller (proxy name or module name, dependings on langage, script, caller...) DEPRECATED

Returns:: nID: ID of the new created task (0 if error)

boost::shared_ptr<ALFunctorBase> AL::ALProxy::getFunctor	(	const std::string &	pName,

Get a pointer to a method form its name and its parameters.

Parameters:

pName	name of the method
pParamTypes	parameters' list

Returns:: a pointer to the method

int AL::ALProxy::getInfo ( ALModuleInfo & pModuleInfo )

Get information about the module stored into pModuleInfo.

Parameters:

pModuleInfo reference to the module information found

boost::shared_ptr<ALModule> AL::ALProxy::getModule ( ) const

Get the module.

Returns:: a pointer to the module

Get the moduleCore.

Returns:: a pointer to the moduleCore

boost::shared_ptr<ALBroker> AL::ALProxy::getParentBroker ( void ) const

Get the parent broker.

Returns:: a pointer to the parent broker

boost::shared_ptr<ALProxy> AL::ALProxy::getThis ( )

Get a pointer to this ALProxy.

Returns:: A pointer to this

boost::shared_ptr<const ALProxy> AL::ALProxy::getThis ( ) const

Get a pointer to this ALProxy.

Returns:: A const pointer to this

bool AL::ALProxy::isLocal ( )

Check if the module is in the same process than the proxy.

Returns:: true if the module is in the same process, false otherwise

bool AL::ALProxy::isRunning ( const int & id )

Check if the method is running.

Parameters:

id	the ID of the method that was returned when calling the method using 'post'

Returns:: true if the method is currently running.

bool AL::ALProxy::isValid ( )

Make sure that we notice that someone has invalidated our module.

This check is done before each specialized proxy's use of a method ptr.

Returns:: true if the module is valide, false otherwise

std::string AL::ALProxy::remoteBrokerName ( )

return the name of the remote broker

Returns:: name of the remote broker, "" is it's a local broker

void AL::ALProxy::stop ( const int & id )

Stop a long running method that was called using 'post'.

Parameters:

id	the ID of the method that was returned when calling the method using 'post'

std::string AL::ALProxy::version ( )

Get the version.

Returns:: the revision number as a string

bool AL::ALProxy::wait	(	const int &	id,
		const int &	timeoutPeriod
	)

Wait for the end of a long running method that was called using 'post'.

Parameters:

id	the ID of the method that was returned when calling the method using 'post'
timeoutPeriod	the timeout period in ms. To wait indefinately, use a timeoutPeriod of zero

Returns:: true if the timeout period terminated. false if the method returned.
