Member Function Documentation

◆ getTypeId()

SoType ScXMLStateMachine::getTypeId ( void  ) const
virtual

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and "downward" casting.

See also
SoBase::getTypeId() const

Implements ScXMLEventTarget.

Reimplemented in SoScXMLStateMachine.

◆ setSessionId()

void ScXMLStateMachine::setSessionId ( const SbName sessionidarg)
virtual

This sets the session identifier for the state machine. Using this is optional, since state machines are already assigned unique session ids at construction-time.

◆ getSessionId()

const SbName & ScXMLStateMachine::getSessionId ( void  ) const

Returns the session identifier string for the state machine.

◆ initialize()

void ScXMLStateMachine::initialize ( void  )
virtual

Fire up the engine.

◆ isActive()

SbBool ScXMLStateMachine::isActive ( void  ) const
virtual

Returns whether the state machine is active or not.

◆ isFinished()

SbBool ScXMLStateMachine::isFinished ( void  ) const
virtual

Returns whether the state machine has run to completion or not.

◆ getNumActiveStates()

int ScXMLStateMachine::getNumActiveStates ( void  ) const
virtual

This method returns the current event during event processing, and NULL when not processing events.

Event processing is in special cases done with NULL as the current event, as for instance during state machine initialization.

Returns the number of active states in the state machine. This number should currently be 1, but in the future, when <parallel> is implemented, it can be more.

◆ getActiveState()

const ScXMLElt * ScXMLStateMachine::getActiveState ( int  idx) const
virtual

Returns the Nth active state.

◆ addDeleteCallback()

void ScXMLStateMachine::addDeleteCallback ( ScXMLStateMachineDeleteCB cb,
void *  userdata 
)
virtual

Registers a callback to be called when the state machine object is being deleted.

◆ removeDeleteCallback()

void ScXMLStateMachine::removeDeleteCallback ( ScXMLStateMachineDeleteCB cb,
void *  userdata 
)
virtual

Unregisters a callback to be called when the state machine object is being deleted.

◆ addStateChangeCallback()

void ScXMLStateMachine::addStateChangeCallback ( ScXMLStateChangeCB callback,
void *  userdata 
)
virtual

Registers a callback to be called when the state machine exits or enters a state.

◆ removeStateChangeCallback()

void ScXMLStateMachine::removeStateChangeCallback ( ScXMLStateChangeCB callback,
void *  userdata 
)
virtual

Unregisters a callback to be called when the state machine exits or enters a state.

◆ processOneEvent()

SbBool ScXMLStateMachine::processOneEvent ( const ScXMLEvent event)
protectedvirtual

Processes one event. This is an internal inner event-loop utility function.

Reimplemented from ScXMLEventTarget.
