class | osg::Program |
osg::Shader is an application-level abstraction of an OpenGL glShader. It is a container to load the shader source code text and manage its compilation. An osg::Shader may be attached to more than one osg::Program. Shader will automatically manage per-context instancing of the internal objects, if that is necessary for a particular display configuration.
typedef std::multimap<float, std::string> osg::Shader::CodeInjectionMap |
The code injection map used when generating the main shader during main shader composition.

Add code injection that will be placed in the main shader to enable support for this shader. The position is set up so that code to be inserted before the main() will have a negative value, a position between 0 and 1.0 will be inserted in main() and a position greater than 1.0 will be placed after the main(). During shader composition all the code injections are sorted in ascending order and then placed in the appropriate section of the main shader.
