Detailed Description

This class is used internally by osgFX::Effect to choose between different techniques dynamically.

The apply() method will call each technique's validate() method and store the results in a buffered array. The Effect class will then choose the first technique that could be validated in all active rendering contexts.

Member Function Documentation

void osgFX::Validator::apply ( osg::State  )  const [virtual]

apply the OpenGL state attributes.

The render info for the current OpenGL context is passed in to allow the StateAttribute to obtain details on the the current context and state.

Reimplemented from osg::StateAttribute.

int osgFX::Validator::compare ( const osg::StateAttribute sa  )  const [inline]
void osgFX::Validator::compileGLObjects ( osg::State  )  const [virtual]

Default to nothing to compile - all state is applied immediately.

Reimplemented from osg::StateAttribute.

void osgFX::Validator::disable (  )  [inline]
osgFX::Validator::META_StateAttribute ( osgFX  ,
Validator  ,
VALIDATOR   
)
Validator& osgFX::Validator::operator= ( const Validator  )  [inline, protected]

disallow any copy operator.

Reimplemented from osg::Object.
