Class Node<V>

java.lang.Object

zipkin2.internal.Node<V>

Type Parameters:

V - the node's value. Ex a full span or a tuple like (serviceName, isLocal)

public final class Node<V>
extends Object

Convenience type representing a tree. This is here because multiple facets in zipkin require traversing the trace tree. For example, looking at network boundaries to correct clock skew, or counting requests imply visiting the tree.
