## devisor2.grid.backend
Class GridCloner

    java.lang.Object
      devisor2.grid.backend.GridCloner

public class GridCloner
extends java.lang.Object

This class performs the actual cloning which is basically used for the copy&paste operation. Here is how it works to make sure that not only shallow copies are created, but that after cloning, the object references are correct.
A Vector of selected items is passed as input for this class. Firstly, the given nodes are cloned, which means all the nodes contained in the vector and the nodes implicitely contained (as part of Tri and Quad elements or as BoundaryNodes). The original ones and the cloned copies are both stored in an array at the same index so that later on, it is still possible to figure out what node is a clone of what node.
After that, the elements are cloned shallowly, and for every node contained in the original, its clone is assigned to the element clone.
After that, parent-child-relationships are updated in the cloned elements. Last but not least, the affine transform to the new position is applied, and everything is added to the Domain.
This class provides methods to perform that, but is not intelligent: The whole copy&paste operation is controlled by the GridListener and MainActionListener classes. See there for more details about how this class is to be used.
