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.

Definition at line 61 of file Transformation.cxx.

References ot::Node::getChild(), ot::Node::getEvent(), ot::Node::isEventQueue(), ot::Event::null, and transformEvent().

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.

Definition at line 106 of file Transformation.cxx.

References ot::Node::getChild(), ot::Node::getEventAtTime(), ot::Node::isTimeDependend(), ot::Event::null, and transformEvent().

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.

Definition at line 76 of file Transformation.cxx.

References ot::Node::getChild(), ot::Node::getEventNearTime(), ot::Node::isEventQueue(), ot::Event::null, and transformEvent().

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.

Definition at line 91 of file Transformation.cxx.

References ot::Node::getChild(), ot::Node::getSize(), and ot::Node::isEventQueue().

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.

Definition at line 121 of file Transformation.cxx.

References ot::Node::getChild(), and ot::Node::isEventGenerator().

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.

Definition at line 133 of file Transformation.cxx.

References ot::Node::getChild(), and ot::Node::isEventQueue().

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.

Definition at line 145 of file Transformation.cxx.

References ot::Node::getChild(), and ot::Node::isTimeDependend().

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.

Definition at line 157 of file Transformation.cxx.

References transformEvent(), and ot::Node::updateObservers().

Referenced by ot::DynamicTransformation::onEventGenerated().

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
