Member Function Documentation

virtual const char* osg::BufferData::className ( ) const
inlinevirtual

return the name of the object's class type. Must be defined by derived classes.

Implements osg::Object.

Reimplemented in osg::DrawElementsUInt, osg::DrawElementsUShort, osg::DrawElementsUByte, osg::DrawArrayLengths, osg::DrawArrays, osg::PrimitiveSet, osg::Image, osg::Array, osg::ImageSequence, and osg::ImageStream.

void osg::BufferData::dirty ( )
inline

Dirty the primitive, which increments the modified count, to force buffer objects to update. If a ModifiedCallback is attached to this BufferData then the callback is called prior to the bufferObject's dirty is called.

References osg::BufferData::ModifiedCallback::modified().

inline
const ModifiedCallback* osg::BufferData::getModifiedCallback ( ) const

unsigned int osg::BufferData::getModifiedCount ( ) const

Get modified count value.

virtual unsigned int osg::BufferData::getTotalDataSize ( ) const
pure virtual
virtual bool osg::BufferData::isSameKindAs ( const Object obj) const
inlinevirtual
virtual const char* osg::BufferData::libraryName ( ) const
inlinevirtual

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::DrawElementsUInt, osg::DrawElementsUShort, osg::DrawElementsUByte, osg::DrawArrayLengths, osg::DrawArrays, osg::PrimitiveSet, osg::Image, osg::Array, osg::ImageSequence, and osg::ImageStream.

void osg::BufferData::releaseGLObjects ( State state = 0) const
virtual

If State is non-zero, this function releases OpenGL objects for the specified graphics context. Otherwise, releases OpenGL objects for all graphics contexts.

Reimplemented from osg::Object.

virtual void osg::BufferData::resizeGLObjectBuffers ( unsigned int  maxSize)
virtual

Resize any per context GLObject buffers to specified size.

Reimplemented from osg::Object.

void osg::BufferData::setBufferIndex ( unsigned int  index)
inline
void osg::BufferData::setBufferObject ( BufferObject bufferObject)
void osg::BufferData::setModifiedCallback ( ModifiedCallback md)
inline
void osg::BufferData::setModifiedCount ( unsigned int  value)
inline

Set the modified count value.
