Type Parameters:

V - The rule key type.

All Implemented Interfaces:

TrackableRuleKeyCache<V>

public class DefaultRuleKeyCache<V>
extends Object
implements TrackableRuleKeyCache<V>

A RuleKey cache used by a RuleKeyFactory. Inputs and dependencies of cached rule keys are tracked to allow for invalidations based on changed inputs. As such, this cache is usable between multiple build runs.
