Class ForwardingRuleKeyHasher<HASH,HASH2>

java.lang.Object

com.facebook.buck.rules.keys.hasher.ForwardingRuleKeyHasher<HASH,HASH2>

All Implemented Interfaces:

RuleKeyHasher<HASH>

public abstract class ForwardingRuleKeyHasher<HASH,HASH2>
extends Object
implements RuleKeyHasher<HASH>

A RuleKeyHasher that forwards all the methods to the two underlying hashers.

hash() invokes the method of the both underlying hashers and returns the hash of the first one.
