Detailed Description

Represents the action state for the Fibonacci action.

This class manages goal creation, response handling, and feedback processing for the Fibonacci action.

Constructor & Destructor Documentation

FibonacciState()

FibonacciState::FibonacciState ( )

inline

Constructs a new FibonacciState object and initializes callbacks.

Member Function Documentation

create_goal_handler()

Fibonacci::Goal FibonacciState::create_goal_handler ( yasmin::Blackboard::SharedPtr blackboard )

inline

Callback for creating the Fibonacci action goal.

Reads the order of the Fibonacci sequence from the blackboard.

Parameters

blackboard

Shared pointer to the blackboard.

Returns

The Fibonacci goal with the specified order.

print_feedback()

void FibonacciState::print_feedback ( yasmin::Blackboard::SharedPtr blackboard, std::shared_ptr< const Fibonacci::Feedback > feedback )

inline

Callback for printing action feedback.

Displays each new partial Fibonacci sequence number as it is received.

Parameters

blackboard	Shared pointer to the blackboard (not used in this method).
feedback	Shared pointer to the feedback message with partial sequence.

response_handler()

std::string FibonacciState::response_handler ( yasmin::Blackboard::SharedPtr blackboard, Fibonacci::Result::SharedPtr response )

inline

Callback for handling the action response.

Stores the resulting Fibonacci sequence in the blackboard.

Parameters

blackboard	Shared pointer to the blackboard.
response	Shared pointer to the action result containing the sequence.

Returns

The outcome status indicating success.
