Class NodeId

java.lang.Object

com.google.inject.grapher.NodeId

public final class NodeId
extends java.lang.Object

ID of a node in the graph. An ID is given by a Key and a node type, which is used to distinguish instances and implementation classes for the same key. For example bind(Integer.class).toInstance(42) produces two nodes: an interface node with the key of Key<Integer> and an instance node with the same Key and value of 42.
