Member Function Documentation

Event & ot::Transformation::getEvent (  unsigned int  number = 0  )  [virtual]

returns the event number n back in time starting with the newest for n = 0 Reimplemented from ot::Node.

Event & ot::Transformation::getEventAtTime (  double  time  )  [virtual]

the function evaluation method. Parameters: time  the point in time at which function is evaluated Returns: reference to event value Reimplemented from ot::Node.

Event & ot::Transformation::getEventNearTime (  double  time  )  [virtual]

returns the event closest to a given point in time. Parameters: time  the point in time in milliseconds since 1.1.1970 Returns: reference to the value of the event. Reimplemented from ot::Node.

unsigned int ot::Transformation::getSize (   )  [virtual]

returns the size of the queue. Uses the childs implementation, if possible. Returns: size of queue Reimplemented from ot::Node.

int ot::Transformation::isEventGenerator (   )  [virtual]

tests for EventGenerator interface being present. Returns the result of the childs implementation of this method. Returns: 1 if child implements EventGenerator, 0 otherwise Reimplemented from ot::Node.

int ot::Transformation::isEventQueue (   )  [virtual]

tests for EventQueue interface being present. Returns the result of the childs implementation of this method. Returns: 1 if child implements EventQueue, 0 otherwise Reimplemented from ot::Node.

int ot::Transformation::isTimeDependend (   )  [virtual]

tests for TimeDependend interface being present. Returns the result of the childs implementation of this method. Returns: 1 if child implements TimeDependend, 0 otherwise Reimplemented from ot::Node.

void ot::Transformation::onEventGenerated (  Event &  event, Node &  generator )  [virtual]

this method is called by the EventGenerator to update it's observers. This class computes a transformed event, stores it in its local variable and notifies its observers in turn, propagating the change. Reimplemented from ot::Node. Reimplemented in ot::DynamicTransformation, and ot::CustomTransformation.

virtual Event* ot::Transformation::transformEvent (  Event *  event  )  [protected, pure virtual]

transforms a event. Simplifies implementing other Transformations as it is only needed to override this method. It stores the transformed event in the localEvent member variable and returns a pointer to it. Parameters: event  pointer to original event Returns: pointer to localEvent member Implemented in ot::EllipsoidTransformNode, ot::GKTransformNode, ot::InvertTransformation, ot::MatrixTransformation, ot::StaticTransformation, ot::VirtualTransformation, and ot::SpeechTransformation.
