Virtual destructor.
virtual MyDXFLine* MyDXFLine::copy | ( | void | ) | const [inline, virtual] |
Get a new copy of entity.
Implements MyDXFEntity.

virtual void MyDXFLine::explode | ( | class MyDXFEntities * | ent, |
MyDXFFile * | dxf, | ||
const Transformation * | t | ||

Explode into entities.
Break entity into atomic entities and tranform entities them with tranformation t. Add the tranformed entities to the database ent.
