Detailed Description

The HFSM class. Builds on the FSM class by overriding the receive function and adding state hierarchy walking functions.

Member Function Documentation

◆ reset()

virtual void etl::hfsm::reset ( bool call_on_exit_state = false)
inlinevirtual

Reset the HFSM to pre-started state.

Parameters
call_on_exit_stateIf true will call on_exit_state() for the current state. Default = false.

Reimplemented from etl::fsm.

◆ start()

void etl::hfsm::start ( bool call_on_enter_state = true)
inlinevirtual

Starts the HFSM. Can only be called once. Subsequent calls will do nothing.

Parameters
call_on_enter_stateIf true will call on_enter_state() for the first state. Default = true. If the first state has child states then they will be recursively entered.

Reimplemented from etl::fsm.
