public abstract class BlockId
extends Object

:: DeveloperApi :: Identifies a particular Block of data, usually associated with a single file. A Block can be uniquely identified by its filename, but each type of Block has a different set of keys which produce its unique name.

If your BlockId should be serializable, be sure to add it to the BlockId.apply() method.
