Examples of DepthFirstWalker

org.apache.pig.experimental.plan.DepthFirstWalker
Do a depth first traversal of the graph.
org.apache.pig.impl.plan.DepthFirstWalker
DepthFirstWalker traverses a plan in a depth first manner. One important note is that, in compliance with the PlanWalker contract, it only visits each node in the graph once.
org.apache.pig.newplan.DepthFirstWalker
Do a depth first traversal of the graph.
