org.codehaus.janino.util.Traverser

This class traverses the subnodes of an AST. Derived classes may override individual methods to process specific nodes, e.g.:

 LocalClassDeclaration lcd = ...; lcd.accept(new Traverser() { int n = 0; public void traverseMethodDeclarator(Java.MethodDeclarator md) { ++this.n; super.traverseMethodDeclarator(md); } }.comprehensiveVisitor());

org.neo4j.graphdb.Traverser
} Relationships are equally well traversed regardless of their direction, performance-wise.
For more usage examples please refer to the wiki documentation. @see Node#traverse
org.neo4j.graphdb.traversal.Traverser
This interface represents the traverser which is used to step through the results of a traversal. Each step can be represented in different ways. The default is as {@link Path} objects which all other representations can bederived from, i.e {@link Node} or {@link Relationship}. Each step can also be represented in one of those representations directly.
