question: public Object resetEdge ( Object edge ) { mxGeometry geo = model . getGeometry ( edge ) ; if ( geo != null ) { List < mxPoint > points = geo . getPoints ( ) ; if ( points != null && ! points . isEmpty ( ) ) { geo = ( mxGeometry ) geo . clone ( ) ; geo . setPoints ( null ) ; model . setGeometry ( edge , geo ) ; } } return edge ; }
target:  Resets the control points of the given edge.
