Detailed Description

ALModule can be used as a base class for user modules to help serve and advertise their methods.

Each module advertises the methods that it wishes to make available to clients participating in the network to a broker within the same process.

The broker then transparently handles directory services so that clients need not know if the module that provides a service is in the same process, on the same machine, or on the same tcp network.

Within the same process, direct method calls are used to provide optimal speed without having to change your method signatures.

Clients exist in a growing number of languages including c++, Python, .Net, Java and Matlab.

Constructor & Destructor Documentation

AL::ALModule::ALModule	(	boost::shared_ptr< ALBroker >	pBroker,
		const std::string &	pName
	)

Creates an ALModule.

An ALModule has a name, and is registered in a broker, so that its methods can be called by other modules, via a proxy constructed with module's name.

Parameters

pBroker	Pointer to a broker
pName	The name for the new module. This is used as the prefix for all method calls e.g. MyModule.myMethod()

virtual AL::ALModule::~ALModule ( )

virtual

Destructor.

Member Function Documentation

template<class T >

static boost::shared_ptr<T> AL::ALModule::createModule ( boost::shared_ptr< ALBroker > pBroker )

inlinestatic

Create a module and link it to a broker.

Parameters

pBroker Pointer to the broker

Returns: A pointer to the module

Exceptions

ALError

Definition at line 117 of file almodule.h.

template<class T , typename P1 >

static boost::shared_ptr<T> AL::ALModule::createModule	(	boost::shared_ptr< ALBroker >	pBroker,
		P1	p1
	)

inlinestatic

Create a module and link it to a broker.

Parameters

pBroker	Pointer to the broker
p1	first parameter after pBroker for the module's constructor

Returns: A pointer to the module

Exceptions

ALError

Definition at line 143 of file almodule.h.

virtual void AL::ALModule::exit ( )

virtual

Exit the module and unregister it.

Reimplemented from AL::ALModuleCore.

QI_API_DEPRECATED void AL::ALModule::functionStop ( int pIDTask )

deprecated

Find the the right module corresponding to the task and call the stop method. Use ProxyModule.stop(...) for remote/local compatibility

Parameters

pIDTask task's ID

Deprecated:

int AL::ALModule::getMethodID ( void )

Return unique ID if method call.

Useful to check for instance if user asked your method to stop. First get ID with getMethodID, then call isRequireStop

Returns: Method's ID

virtual void AL::ALModule::init ( void )

inlinevirtual

It will be called at every module creation, user can overload it.

Reimplemented from AL::ALModuleCore.

Definition at line 254 of file almodule.h.

bool AL::ALModule::isPCalled ( )

Check if the module is pcalled.

Returns: true if pcalled, false otherwise

bool AL::ALModule::isRunning ( const int & taskId )

Determines if the method created with a 'post' is still running.

Parameters

taskId The id of the method that was returned by 'post'

Returns: true if the method is still running, false otherwise

bool AL::ALModule::isStopRequired ( const int & taskId = -1 )

Check if the user call stop.

Parameters

taskId The id of the method that was returned by 'post'

Returns: true if used call stop, false otherwise

virtual void AL::ALModule::stop ( const int & taskId )

virtual

Stops a module's method using the ID given returned by a 'post' call. Module authors are encouraged to implement this if they have long running methods that they wish to allow users to interrupt.

Warning: Module has to overload stop method or an exception will be raised.

Parameters

taskId The id of the method that was returned by 'post'

bool AL::ALModule::wait	(	const int &	taskId,
		const int &	timeout
	)

Waits until the end of a long running method using the ID that was returned from a method started with 'post'.

Parameters

taskId	The id of the method that was returned by 'post'
timeout	The wait timeout period in ms. If 0 wait indefinately.

Returns: true if the timeout period expired, false otherwise

qi::FutureSync<void> AL::ALModule::wait ( const int & taskId )

Waits until the end of a long running method using the ID that was returned from a method started with 'post'.

Parameters

taskId The id of the method that was returned by 'post'

Returns: a cancelable future
