NAMEScXMLEventTarget − base class for event targets for inter-system event communication

SYNOPSIS
#include <Inventor/scxml/ScXMLEventTarget​.h> Inherits ScXMLObject​. Inherited by ScXMLStateMachine, and SoScXMLNavigationTarget​.

Public Member Functionsvirtual SoType getTypeId (void) const =0
Returns the type identification of an object derived from a class inheriting SoBase​. This is used for run-time type checking and 'downward' casting​.

Detailed Descriptionbase class for event targets for inter-system event communication This class manages inter-communication between SCXML systems and systems intended for communicating with such systems​. It also manages the external event queue for such systems (systems may also have internal event queues)​. Since Coin 3​.1

Member Function Documentation

virtual SoType ScXMLEventTarget::getTypeId (void) const [pure 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 ScXMLObject​. Implemented in SoScXMLNavigationTarget, SoScXMLStateMachine, ScXMLStateMachine, SoScXMLZoomTarget, SoScXMLSpinTarget, SoScXMLSeekTarget, SoScXMLRotateTarget, SoScXMLPanTarget, SoScXMLMotionTarget, SoScXMLMiscTarget, SoScXMLFlightControlTarget, and SoScXMLDollyTarget​.

const ScXMLEvent * ScXMLEventTarget::getCurrentEvent (void) const [inline], [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​.

void ScXMLEventTarget::queueEvent (const ScXMLEvent * event) [virtual]Queues an ScXMLEvent event​. The event is copied, and can be deleted as soon as the function return​.

void ScXMLEventTarget::queueEvent (const SbName & eventid) [virtual]Queues an ScXMLEvent event that has the given eventid as its event name​.

void ScXMLEventTarget::setCurrentEvent (const ScXMLEvent * event) [protected], [virtual]Sets a pointer for the event that is 'current' during event processing​. This is an internal method, and the updating of the current event should be handled automatically​.

SbBool ScXMLEventTarget::processOneEvent (const ScXMLEvent * event) [protected], [virtual]This function processes one event​. The base class implementation does nothing​. Reimplemented in ScXMLStateMachine, SoScXMLZoomTarget, SoScXMLSpinTarget, SoScXMLSeekTarget, SoScXMLRotateTarget, SoScXMLPanTarget, SoScXMLMotionTarget, SoScXMLMiscTarget, SoScXMLFlightControlTarget, and SoScXMLDollyTarget​.
