       Inherits ScXMLEventTarget.

       Inherited by SoScXMLDollyTarget, SoScXMLFlightControlTarget, SoScXMLMiscTarget,
       SoScXMLMotionTarget, SoScXMLPanTarget, SoScXMLRotateTarget, SoScXMLSeekTarget,

   Public Member Functions
       virtual 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.

Member Function Documentation

   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 run-time type checking and 'downward' casting.

       See Also:
           SoBase::getTypeId() const

       Implements ScXMLEventTarget.

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

   SoScXMLNavigationTarget::Data * SoScXMLNavigationTarget::getSessionData (SbNamesessionid,
       NewDataFunc *constructor) [protected]
       Returns the Data* base handle for the datastructure 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 (SbNamesessionid) [protected]
       Cleans out the data structure that is mapped to the given sessionid.

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

   ScXMLStateMachine * SoScXMLNavigationTarget::getStateMachine (const ScXMLEvent *event,
       SbNamesessionid) [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,
       SbNamesessionid) [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, SbNamesessionid)
       [static],  [protected]
       Returns the current active camera, or NULL if there is no active camera set. If NULL is
       returned, error messages has been posted.

   SbBool SoScXMLNavigationTarget::getEventDouble (const ScXMLEvent *event, const char *label,
       double &dbl_out, SbBoolrequired = 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, SbBoolrequired = 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, SbBoolrequired = 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, SbBoolrequired = 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, SbBoolrequired = 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, SbBoolrequired = 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.
