## Detailed Description

### template<typename T>
class Ogre::ControllerFunction< T >

Subclasses of this class are responsible for performing a function on an input value for a Controller.

Remarks:
  This abstract class provides the interface that needs to be supported for a custom function which can be 'plugged in' to a Controller instance, which controls some object value based on an input value. For example, the WaveControllerFunction class provided by Ogre allows you to use various waveforms to translate an input value to an output value.

  You are free to create your own subclasses in order to define any function you wish.

## Constructor & Destructor Documentation

template<typename T>
Ogre::ControllerFunction< T >::ControllerFunction | ( | bool | deltaInput | ) |

  | Constructor. Parameters:
  | deltaInput | If true, signifies that the input will be a delta value such that the function should add it to an internal counter before calculating the output.
Definition at line 85 of file OgreController.h.

template<typename T>
virtual Ogre::ControllerFunction< T >::~ControllerFunction | ( |  | ) | `[virtual]`

| Definition at line 91 of file OgreController.h.

## Member Function Documentation

template<typename T>
virtual T Ogre::ControllerFunction< T >::calculate | ( | T | sourceValue | ) | `[pure virtual]`

| Implemented in Ogre::PassthroughControllerFunction, Ogre::AnimationControllerFunction, Ogre::ScaleControllerFunction, and Ogre::WaveformControllerFunction.

template<typename T>
T Ogre::ControllerFunction< T >::getAdjustedInput | ( | T | input | ) | `[protected]`

| Gets the input value as adjusted by any delta. Reimplemented in Ogre::WaveformControllerFunction. Definition at line 60 of file OgreController.h.
