Interface UseSite.Visitor<R,P>

Type Parameters:

R - the type of the returned value when done visiting the graph

P - the type of the parameter passed to the visitor

Enclosing class:

UseSite

public static interface UseSite.Visitor<R,P>

A visitor of the use site graph. Note that use sites form a directed CYCLIC graph so care must be taken by the implementor of this interface to avoid infinite loops. The graph traversal code does NOT take care of this automatically.
