  virtual SoType SoScXMLNavigationTarget::getTypeId (void) const [pure virtual]

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and 'downward' casting.

Implements ScXMLEventTarget.

Implemented in SoScXMLZoomTarget, SoScXMLSpinTarget, SoScXMLSeekTarget, SoScXMLRotateTarget, SoScXMLPanTarget, SoScXMLMotionTarget, SoScXMLMiscTarget, SoScXMLFlightControlTarget, and SoScXMLDollyTarget.

  SoScXMLNavigationTarget::Data * SoScXMLNavigationTarget::getSessionData (SbName sessionid, NewDataFunc * constructor) [protected]
Returns the Data* base handle for the data structure that corresponds to the given sessionid. The constructor argument is the function responsible for creating the Data-derived object if the session is new (or have been cleaned up earlier).

  void SoScXMLNavigationTarget::freeSessionData (SbName sessionid) [protected]
Cleans out the data structure that is mapped to the given sessionid.

  SbName SoScXMLNavigationTarget::getSessionId (const ScXMLEvent * event) [static], [protected]
Returns the session id that is associated with the event. If no session id is found, SbName::empty() is returned.

  ScXMLStateMachine * SoScXMLNavigationTarget::getStateMachine (const ScXMLEvent * event, SbName sessionid) [static], [protected]
Returns the state machine that is associated with the given sessionid, or NULL if there are no state machines registered for the session id.

  SoScXMLStateMachine * SoScXMLNavigationTarget::getSoStateMachine (const ScXMLEvent * event, SbName sessionid) [static], [protected]
Returns the So- state machine that is associated with the given sessionid, or NULL if there are no state machines registered for the session id or if the state machine is not of SoScXMLStateMachine type.

  SoCamera * SoScXMLNavigationTarget::getActiveCamera (const ScXMLEvent * event, SbName sessionid) [static], [protected]
Returns the current active camera, or NULL if there is no active camera set. If NULL is returned, error messages have been posted.

  SbBool SoScXMLNavigationTarget::getEventDouble (const ScXMLEvent * event, const char * label, double & dbl_out, SbBool required = TRUE) [static], [protected]
Returns TRUE if a double was delivered with the event under the label label, and FALSE otherwise. If required is TRUE, then errors will be given, otherwise this function will remain quiet.

  SbBool SoScXMLNavigationTarget::getEventString (const ScXMLEvent * event, const char * label, SbString & str_out, SbBool required = TRUE) [static], [protected]
Returns TRUE if a string was delivered with the event under the label label, and FALSE otherwise. If required is TRUE, then errors will be given, otherwise this function will remain quiet.

  SbBool SoScXMLNavigationTarget::getEventSbBool (const ScXMLEvent * event, const char * label, SbBool & bool_out, SbBool required = TRUE) [static], [protected]
Returns TRUE if a boolean value was delivered with the event under the label label, and FALSE otherwise. If required is TRUE, then errors will be given, otherwise this function will remain quiet.

  SbBool SoScXMLNavigationTarget::getEventSbVec2f (const ScXMLEvent * event, const char * label, SbVec2f & vec_out, SbBool required = TRUE) [static], [protected]
Returns TRUE if an SbVec2f was delivered with the event under the label label, and FALSE otherwise. If required is TRUE, then errors will be given, otherwise this function will remain quiet.

  SbBool SoScXMLNavigationTarget::getEventSbVec3f (const ScXMLEvent * event, const char * label, SbVec3f & vec_out, SbBool required = TRUE) [static], [protected]
Returns TRUE if an SbVec3f was delivered with the event under the label label, and FALSE otherwise. If required is TRUE, then errors will be given, otherwise this function will remain quiet.

  SbBool SoScXMLNavigationTarget::getEventSbRotation (const ScXMLEvent * event, const char * label, SbRotation & rot_out, SbBool required = TRUE) [static], [protected]
Returns TRUE if an SbRotation was delivered with the event under the label label, and FALSE otherwise. If required is TRUE, then errors will be given, otherwise this function will remain quiet.
