Interface JitOpVisitor

All Known Subinterfaces:

All Known Implementing Classes:

public interface JitOpVisitor
A visitor for traversing the use-def graph

The default implementations here do nothing other than discern the type of an op and variable and dispatch the invocations appropriately. To traverse the graph upward, consider JitOpUpwardVisitor. Note no "downward" visitor is currently provided, because it was not needed.
