Detailed Description

The WorldFrame class is a class that is used internally to create the singleton World Frame.

This class cannot be instantiated directly: you must use the Frame::World() function to access it. Only one World Frame exists in any application.

Member Function Documentation

◆ setName()

const std::string & dart::dynamics::WorldFrame::setName ( const std::string &  _name)
finaloverridevirtual

Set name.

Some implementations of Entity may make alterations to the name that gets passed in. The final name that this entity will use gets passed back in the return of this function.

Implements dart::dynamics::Entity.
