Detailed Description

Represents a state that executes a callback function.

The CbState class inherits from the State class and is designed to execute a user-defined callback function, utilizing a shared pointer to a Blackboard object to obtain necessary data.

Constructor & Destructor Documentation

◆ CbState()

yasmin::CbState::CbState	(	const std::set< std::string > &	outcomes,
		std::function< std::string(std::shared_ptr< blackboard::Blackboard >)>	callback )

Constructs a CbState object.

Parameters

outcomes	A set of possible outcomes for this state.
callback	A function pointer to the callback function that will be executed when this state is activated.

Exceptions

std::invalid_argument If the outcomes set is empty.

Member Function Documentation

◆ execute()

std::string yasmin::CbState::execute ( std::shared_ptr< blackboard::Blackboard > blackboard )

overridevirtual

Executes the callback function.

This function is called to execute the callback and retrieve the result. It may use the provided Blackboard for additional data.

Parameters

blackboard A shared pointer to the Blackboard object used during execution.

Returns: The result of the callback function execution as a string.

Exceptions

std::runtime_error If the callback execution fails.

Reimplemented from yasmin::State.
