## Detailed Description

osgGL2::UniformValue is for internal use by osgGL2::ProgramObject.

UniformValue is an abstract class to encapsulate a new value for a glUniform. osgGL2::ProgramObject.setUniform() constructs and sends a UniformValue to all its PerContextProgramObjects (PCPOs) to set the value of a glUniform. The value contained in each UniformValue value is propagated to the glProgramObjects during the next osgGL2::ProgramObject.apply().
