virtual int osg::LogicOp::compare ( const StateAttribute sa  )  const [inline, virtual]

Return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs.

Implements osg::StateAttribute.

virtual bool osg::LogicOp::getModeUsage ( ModeUsage &  usage  )  const [inline, virtual]

void osg::LogicOp::setOpcode ( Opcode  opcode  )  [inline]

Opcode osg::LogicOp::getOpcode (  )  const [inline]

virtual void osg::LogicOp::apply ( State  )  const [virtual]

apply the OpenGL state attributes. The global state for the current OpenGL context is passed in to allow the StateAttribute to obtain details on the the current context and state.

Implements osg::StateAttribute.
