Package org.synchronoss.cpo.core.transform

Interface CpoTransform<D,J>

Type Parameters:
D - the raw datastore-side type
J - the Java bean-side type
All Known Subinterfaces:
CassandraCpoTransform<D,J>, JdbcCpoTransform<D,J>
All Known Implementing Classes:
TransformCharArray, TransformClob, TransformGZipBytes, TransformNoOp, TransformNoOp, TransformStringByte, TransformStringChar, TransformTimestampToCalendar
public interface CpoTransform<D,J>
CpoTransform converts an attribute's value between the raw form stored/read at the datastore and the form exposed on the Java bean, e.g. clob-to-string or gzip compression. Implementations are configured per-attribute in the meta XML and instantiated reflectively, so they must provide a public no-arg constructor.
