Class SynchronizedTreeTransformer

java.lang.Object
  edu.stanford.nlp.trees.SynchronizedTreeTransformer

All Implemented Interfaces:

TreeTransformer

public class SynchronizedTreeTransformer
extends java.lang.Object
implements TreeTransformer

If you have a TreeTransformer which is not threadsafe, and you need to call it from multiple threads, this will wrap it in a synchronized manner.

Description copied from interface: TreeTransformer

Does whatever one needs to do to a particular tree. This routine is passed a whole Tree, and could itself work recursively, but the canonical usage is to invoke this method via the Tree.transform() method, which will apply the transformer in a bottom-up manner to each local Tree, and hence the implementation of TreeTransformer should merely examine and change a local (one-level) Tree.

Specified by:

transformTree in interface TreeTransformer

Parameters:

t - A tree. Classes implementing this interface can assume that the tree passed in is not null.

Returns:

the transformed Tree
