org.apache.pig.StreamToPig

The interface is used for the custom mapping of a byte array, received from the stdout of the streaming process, to a {@link Tuple}. This interface, together with {@link PigToStream}, is designed to provide a common protocol for data exchange between Pig runtime and streaming executables. The method getLoadCaster is called by Pig to convert the fields in the byte array to typed fields of the Tuple based on a given schema. Typically, user implements this interface for a particular type of stream command and specifies the implementation class in the Pig DEFINE statement. @since Pig 0.7
