CloneCurvesContext Class

Algorithmic class for cloning curve collections.

  • recurse through collection nodes, building image nodes as needed and inserting clones of children.
  • for individual primitive, invoke doClone (protected) for direct clone; insert into parent

Methods

Name Description
constructor(transform?: Transform): CloneCurvesContext Protected    
announceCurvePrimitive(primitive: CurvePrimitive, _indexInParent: number): void process a leaf primitive.  
doClone(primitive: CurvePrimitive): undefined | CurvePrimitive | CurvePrimitive[] Protected    
enter(c: CurveCollection): void Push data onto the stack so its status is available during processing of children.  
leave(): undefined | CurveCollection Pop the stack  
clone(target: CurveCollection, transform?: Transform): undefined | CurveCollection Static
