qi::Session

A session is what allows you to connect services together locally or over the network. They can be used as server or client and can register or obtain services (on all sides, even in multi-client). You can read the guides to register a service and get a service .

Detailed Description

A Session allows you to interconnect services on the same machine or over the network.

qi::FutureSync<qi::AnyObject> qi::Session:: service ( const std::string& name , const std::string& protocol , qi::MilliSeconds timeout )

Returns the asked service.

If the timeout triggers, the returned future is canceled.

qi::FutureSync<unsigned int> qi::Session:: loadService ( const std::string& moduleName , const std::string& renameModule = "", const AnyReferenceVector& args = AnyReferenceVector( )

Load a module and register the specified object on the session

Tries to call the factory with (this, args...) if possible, otherwise it calls it with (args...) only.

template<typename T>
qi::FutureSync<T> qi::Session:: callModule ( const std::string& moduleName , const AnyReferenceVector& args = AnyReferenceVector( )

Load a module and call the specified function asynchronously

Tries to call the function with (this, args...) if possible, otherwise it calls it with (args...) only.

FutureSync<void> qi::Session:: waitForService ( const std::string& servicename , MilliSeconds timeout )

Waits for a service to become available and fails if the timeout has expired. The future is set immediately if the service is already available. The future is canceled if the timeout triggered.

qi::FutureSync<void> qi::Session:: waitForService ( const std::string& service )

Waits for a service to become available. The future is set immediately if the service is already available. The timeout used is given by defaultWaitForServiceTimeout().
