Interface Key

All Known Implementing Classes:

EmptySignature, MediaStoreSignature, StringSignature

public interface Key

An interface that uniquely identifies some set of data. Implementations must implement Object.equals(Object) and Object.hashCode(). Implementations are generally expected to add all uniquely identifying information used in in Object.equals(Object)} and Object.hashCode()} to the given MessageDigest in updateDiskCacheKey(java.security.MessageDigest)}, although this requirement is not as strict for partial cache key signatures.
