public interface Key

An interface that uniquely identifies some put 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.

Method Details

updateDiskCacheKey

void updateDiskCacheKey(@NonNull
 MessageDigest messageDigest)

Adds all uniquely identifying information to the given digest.

Note - Using MessageDigest.reset() inside of this method will result in undefined behavior.

equals

boolean equals(Object o)

For caching to work correctly, implementations must implement this method and hashCode().

Overrides:

equals in class Object

hashCode

int hashCode()

For caching to work correctly, implementations must implement this method and equals(Object).

Overrides:

hashCode in class Object
