Constructor & Destructor Documentation

osg::BufferData::BufferData ( const BufferData bd,
const CopyOp copyop = CopyOp::SHALLOW_COPY 
) [inline]

Copy constructor using CopyOp to manage deep vs shallow copy.

virtual osg::BufferData::~BufferData ( ) [protected, virtual]

Member Function Documentation

virtual const char* osg::BufferData::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::DrawElementsUInt, osg::DrawElementsUShort, osg::DrawElementsUByte, osg::DrawArrayLengths, osg::DrawArrays, osg::PrimitiveSet, osg::Image, osg::Array, osg::ImageSequence, and osg::ImageStream.

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().

unsigned int osg::BufferData::getBufferIndex ( ) const [inline]
virtual const GLvoid* osg::BufferData::getDataPointer ( ) const [pure virtual]
GLBufferObject* osg::BufferData::getGLBufferObject ( unsigned int  contextID) const [inline]
unsigned int osg::BufferData::getModifiedCount ( ) const [inline]

Get modified count value.

GLBufferObject* osg::BufferData::getOrCreateGLBufferObject ( unsigned int  contextID) const [inline]
virtual unsigned int osg::BufferData::getTotalDataSize ( ) const [pure virtual]
virtual bool osg::BufferData::isSameKindAs ( const Object obj) const [inline, virtual]
virtual const char* osg::BufferData::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::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::setModifiedCount ( unsigned int  value) [inline]

Set the modified count value.
