VariationDiffAdapter

public class VariationTreeAdapter<L extends Label>
extends com.github.gumtreediff.tree.AbstractTree

Adapter for running Gumtree's matching algorithms on variation trees. This class is an adapter for a snapshot of a variation tree. This means that it doesn't reflect most changes to the underlying variation tree. Essentially it creates a copy of the tree structure and the labels of a variation tree by stores a reference to the variation node which it adapts.
