ScXMLStateMachine(3) Coin ScXMLStateMachine(3) NAME ScXMLStateMachine - Manager for processing events and setting states in SCXML structures. SYNOPSIS #include Inherits ScXMLEventTarget. Inherited by SoScXMLStateMachine. Public Member Functions virtual SoType getTypeId (void) const Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and downward"casting. virtual void setName (const SbName &name) const SbName & getName (void) const virtual void setDescription (ScXMLDocument *document) const ScXMLDocument * getDescription (void) const virtual void setSessionId (const SbName &sessionid) const SbName & getSessionId (void) const virtual void initialize (void) virtual SbBool isActive (void) const virtual SbBool isFinished (void) const virtual int getNumActiveStates (void) const virtual const ScXMLElt * getActiveState (int idx) const virtual void addDeleteCallback (ScXMLStateMachineDeleteCB *callback, void *userdata) virtual void removeDeleteCallback (ScXMLStateMachineDeleteCB *callback, void *userdata) virtual void addStateChangeCallback (ScXMLStateChangeCB *callback, void *userdata) virtual void removeStateChangeCallback (ScXMLStateChangeCB *callback, void *userdata) virtual void setVariable (const char *name, const char *value) virtual const char * getVariable (const char *name) const virtual void setLogLevel (int loglevel) int getLogLevel (void) const virtual void setEvaluator (ScXMLEvaluator *evaluator) ScXMLEvaluator * getEvaluator (void) const SbBool isModuleEnabled (const char *modulename) const int getNumEnabledModules (void) const const char * getEnabledModuleName (int idx) const void setEnabledModulesList (const SbList< const char * > &modulenames) Public Member Functions inherited from ScXMLEventTarget virtual void setEventTargetType (const char *targettype) const char * getEventTargetType (void) const virtual void setEventTargetName (const char *targetname) const char * getEventTargetName (void) const virtual const ScXMLEvent * getCurrentEvent (void) const virtual void queueEvent (const ScXMLEvent *event) virtual void queueEvent (const SbName &eventid) virtual SbBool processEventQueue (void) virtual SbBool sendExternalEvent (const ScXMLSendElt *sendelt) virtual SbBool sendInternalEvent (const ScXMLEventElt *sendelt) virtual void queueInternalEvent (const ScXMLEvent *event) virtual void queueInternalEvent (const SbName &eventid) Public Member Functions inherited from ScXMLObject SbBool isOfType (SoType type) const Returns TRUE if the type of this object is either of the same type or inherited from type.

Since Coin 3.0 Member Function Documentation SoType ScXMLStateMachine::getTypeId (void ) const [virtual] Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting. See also SoBase::getTypeId() const Implements ScXMLEventTarget. Reimplemented in SoScXMLStateMachine. 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. const SbName & ScXMLStateMachine::getSessionId (void ) const Returns the session identifier string for the state machine. void ScXMLStateMachine::initialize (void ) [virtual] Fire up the engine. SbBool ScXMLStateMachine::isActive (void ) const [virtual] Returns whether the state machine is active or not. SbBool ScXMLStateMachine::isFinished (void ) const [virtual] Returns whether the state machine has run to completion or not. 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 is implemented, it can be greater. const ScXMLElt * ScXMLStateMachine::getActiveState (int idx) const [virtual] Returns the Nth active state. void ScXMLStateMachine::addDeleteCallback (ScXMLStateMachineDeleteCB * cb, void * userdata) [virtual] Registers a callback to be called when the state machine object is being deleted. void ScXMLStateMachine::removeDeleteCallback (ScXMLStateMachineDeleteCB * cb, void * userdata) [virtual] Unregisters a callback to be called when the state machine object is being deleted. void ScXMLStateMachine::addStateChangeCallback (ScXMLStateChangeCB * callback, void * userdata) [virtual] Registers a callback to be called when the state machine exits or enters a state. void ScXMLStateMachine::removeStateChangeCallback (ScXMLStateChangeCB * callback, void * userdata) [virtual] Unregisters a callback to be called when the state machine exits or enters a state. const char * ScXMLStateMachine::getVariable (const char * name) const [virtual] Reimplemented in SoScXMLStateMachine. SbBool ScXMLStateMachine::processOneEvent (const ScXMLEvent * event) [protected], [virtual] Processes one event. This is an internal inner event-loop utility function.
