[osg-users] pfObject::getNamedUserDataSlot

[Robert Osfield]

Hi Tony,

The name of the osg::Object is used as a key in UserDataContainerL  see the
methods:

       /** Get the index position of first user data object that matches
specified name.*/
        virtual unsigned int getUserObjectIndex(const std::string& name,
unsigned int startPos=0) const = 0;

        /** Get first user data object with specified name. */
        virtual Object* getUserObject(const std::string& name, unsigned int
startPos=0);

        /** Get first const user data object with specified name. */
        virtual const Object* getUserObject(const std::string& name,
unsigned int startPos=0) const;

Robert.
