Member Function Documentation

§ accept()

virtual void osg::AutoTransform::accept ( NodeVisitor nv)
virtual

Visitor Pattern : calls the apply method of a NodeVisitor with this node's type.

Reimplemented from osg::Node.

§ asAutoTransform() [1/2]

virtual AutoTransform* osg::AutoTransform::asAutoTransform ( )
inlinevirtual

§ asAutoTransform() [2/2]

virtual const AutoTransform* osg::AutoTransform::asAutoTransform ( ) const
inlinevirtual

§ className()

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

return the name of the node's class type.

Reimplemented from osg::Node.

§ clone()

virtual osg::Object* osg::AutoTransform::clone ( const osg::CopyOp copyop) const
inlinevirtual

return a clone of a node, with Object* return type.

Reimplemented from osg::Node.

§ cloneType()

virtual osg::Object* osg::AutoTransform::cloneType ( ) const
inlinevirtual

clone an object of the same type as the node.

Reimplemented from osg::Node.

§ computeBound()
