Implement the Proper Interface

Note that OpenNI has a different interface for a node implementation than the actual API of the node. However sometimes very similar, those interfaces are different.

The module's interfaces (C++ ones) are defined in file XnModuleCppInterface.h.

The following table lists current OpenNI node types and their module interface.

Node Type	Module Interface
Production Node	xn::ModuleProductionNode
Device	xn::ModuleDevice
Generator	xn::ModuleGenerator
Recorder	xn::ModuleRecorder
Player	xn::ModulePlayer
Map Generator	xn::ModuleMapGenerator
Depth Generator	xn::ModuleDepthGenerator
Image Generator	xn::ModuleImageGenerator
IR Generator	xn::ModuleIRGenerator
Gestures Generator	xn::ModuleGestureGenerator
Scene Analyzer	xn::ModuleSceneAnalyzer
Hands Generator	xn::ModuleHandsGenerator
User Generator	xn::ModuleUserGenerator
Audio Generator	xn::ModuleAudioGenerator
Codec	xn::ModuleCodec
Script	xn::ModuleScriptNode

Our newly created class should inherit virtually from the proper interface. For example, if we're creating a hand generator then our class declaration should start with:

class MyHandGenerator: public virtual xn::ModuleHandsGenerator
{
...
};
