Class TargetGraphHashing

java.lang.Object

com.facebook.buck.core.model.targetgraph.impl.TargetGraphHashing

public class TargetGraphHashing
extends Object

Utility class to calculate hash codes for build targets in a TargetGraph.

A build target's hash code is guaranteed to change if the build target or any of its dependencies change, including the contents of all input files to the target and its dependencies.
