Class CAnimator

class CAnimator : public CBase;

Description

Pure virtual base class for animators.

Each data type supported by the animation framework is represented by an animator, which handles the data interpretation, timing and control. Each animator is provided in the form of an ECOM plugin.

You do not need to instatiate animators in a client application. This is handled by the animation classes.

Derivation

• CBase - Base class for all classes to be instantiated on the heap

• CAnimator - Pure virtual base class for animators

static IMPORT_C CAnimator *NewL(MAnimationDrawer *aRenderer);

Description

Locates and constructs an animator.

The MAnimationDrawer passed as an argument returns a string through the function AnimatorDataType. If a matching animator plugin can be found then it will be loaded and constructed.

Parameters

MAnimationDrawer *aRenderer The MAnimationDrawer implementation for the animator to use.

Return value

CAnimator * The new animator.

virtual IMPORT_C ~CAnimator();

Description

Destructor.

virtual void Start(const TAnimationConfig &aConfig)=0;
