Member Function Documentation

std::shared_ptr< InvokerImpl > uscxml::USCXMLInvoker::create ( InvokerCallbacks * callbacks )

virtual

Parameters

callbacks An object implementing the invoker callbacks.

void uscxml::USCXMLInvoker::deserialize ( const Data & encodedState )

virtual

Parameters

encodedState The state we returned somewhen else via serialize.

Reimplemented from uscxml::InvokerImpl.

Data uscxml::USCXMLInvoker::getDataModelVariables ( )

virtual

void uscxml::USCXMLInvoker::invoke	(	const std::string &	source,
		const Event &	invokeEvent
	)

virtual

Parameters

source	The content of the invoke's `src` or evaluated `srcexpr` attribute
invokeEvent	The invocation with all its data as an event

void uscxml::USCXMLInvoker::stop ( )

protected

We cannot join the invoked thread if it is blocking at an external receive. Cancel will finalize and unblock.
