virtual bool osg::PrimitiveSet::isSameKindAs ( const Object obj  )  const [inline, virtual]

virtual const char* osg::PrimitiveSet::libraryName (  )  const [inline, virtual]

return the name of the object's library.

Must be defined by derived classes. The OpenSceneGraph convention is that the namespace of a library is the same as the library name.

Implements osg::Object.

Reimplemented in osg::DrawArrays, osg::DrawArrayLengths, osg::DrawElementsUByte, osg::DrawElementsUShort, and osg::DrawElementsUInt.

virtual const char* osg::PrimitiveSet::className (  )  const [inline, virtual]

return the name of the object's class type.

Must be defined by derived classes.

Implements osg::Object.

Reimplemented in osg::DrawArrays, osg::DrawArrayLengths, osg::DrawElementsUByte, osg::DrawElementsUShort, and osg::DrawElementsUInt.

Set the modified count value.

unsigned int osg::PrimitiveSet::getModifiedCount (  )  const [inline]

Get modified count value.

virtual void osg::PrimitiveSet::resizeGLObjectBuffers ( unsigned int   )  [inline, virtual]
