```
public class PathMappedAccumulatorData
extends java.lang.Object
implements IAccumulatorData
```
Accumulator data for a tree that is obtained by mapping the nodes in this tree to nodes in some other tree (specifically, the subtree from which this tree was originally copied with copy-accumulators=yes) and getting the accumulator value from the corresponding node in the other tree.
