◆ discoverOpenGLavailability()

virtual bool PureHwVideoDiscoverOpenGL_1_3::discoverOpenGLavailability ( )
inlinevirtual

This method checks for related OpenGL extensions, however final verdict on extension support is declared by Discover...Availability() functions of this class.

Some higher level manager first invokes this method, then later based on some logic it invokes the Discover...Availability() functions of this class. This class doesn't limit the way you invoke its public functions as this class is not intended to have that kind of logic, however the order is important from the perspective of the logic of the higher-level class, including logging.
