Detailed Description

template<class Table, class Logger = empty_logger>
struct pure::state_machine< Table, Logger >

State Machine.

Template Parameters

Table	transition_table
Logger	type that provides a logger interface

Constructor & Destructor Documentation

state_machine()

template<class Table , class Logger = empty_logger>

pure::state_machine< Table, Logger >::state_machine ( logger_t  custom_logger )

inline

Constructor that allows to initialize a logger.

If the user-defined logger needs some internal data initialization, user can define a template type of State Machine as a reference to a logger and pass a logger by reference; or pass it by value.

Member Function Documentation

action()

template<class Table , class Logger = empty_logger>

template<typename... Args>

void pure::state_machine< Table, Logger >::action ( Args &&...  args )

inline

Calls a state action.

Template Parameters

Args...

variadic template type pack of arguments

If the current state type is a functor and it is can be called with the given arguments, it will be called.

event()

template<class Table , class Logger = empty_logger>

template<typename Event , typename... Args>

void pure::state_machine< Table, Logger >::event ( Args &&...  args )

inline

Pass an event to a State Machine.

Template Parameters

Event	event
Args...	variadic template type pack of arguments

Input impact for State Machine. If the there is a transition, for which current state, current guard and an event are matched, the transition will be performed.

If the given event causes a transition, and this transition has an action, it will be called with the arguments Args....

guard()

template<class Table , class Logger = empty_logger>

template<class Guard >

void pure::state_machine< Table, Logger >::guard ( )

inline

Change current guard.

Template Parameters

Guard

next guard
