Examples of TreeVisitor

com.foundationdb.server.service.tree.TreeVisitor
edu.stanford.nlp.trees.TreeVisitor
This is a simple strategy-type interface for operations that are applied to Tree. It typically is called iteratively over trees in a Treebank. The convention is for TreeVisitor implementing classes not to affect Tree instances they operate on, but to accomplish things via side effects (like counting statistics over trees, etc.). @author Christopher Manning @author Roger Levy
melnorme.utilbox.tree.TreeVisitor
Generic tree walker that can walk any TreeNode. Uses TreeNode.getChildren();
org.antlr.runtime.tree.TreeVisitor
Do a depth first walk of a tree, applying pre() and post() actions as we discover and finish nodes.
