All the implementation 00032 // details are in the subclasses. 00033 //////////////////////////////////////////////////////////////////// 00034 00035 class EXPCL_PANDA_GOBJ ShaderContext: public SavedContext { 00036 public: 00037 INLINE ShaderContext(Shader *se); 00038 00039 PUBLISHED: 00040 INLINE Shader *get_shader() const; 00041 00042 public: 00043 Shader *_shader; 00044 00045 public: 00046 static TypeHandle get_class_type() { 00047 return _type_handle; 00048 } 00049 static void init_type() { 00050 TypedObject::init_type(); 00051 register_type(_type_handle, "ShaderContext", 00052 TypedObject::get_class_type()); 00053 } 00054 virtual TypeHandle get_type() const { 00055 return get_class_type(); 00056 } 00057 virtual TypeHandle force_init_type() {init_type(); return get_class_type();} 00058 00059 private: 00060 static TypeHandle _type_handle; 00061 }; 00062 00063 #include "shaderContext.I" 00064 00065 #endif
