Package org.apache.cayenne.access.types
Class ByteType
- java.lang.Object
-
- org.apache.cayenne.access.types.ByteType
-
- All Implemented Interfaces:
ExtendedType<Byte>
public class ByteType extends Object implements ExtendedType<Byte>
Handlesjava.lang.Bytetype mapping. Can be configured to recast java.lang.Byte to java.lang.Integer when binding values to PreparedStatement. This is a workaround for bugs in certain drivers. Drivers that are proven to have issues with byte values are Sybase and Oracle (Mac OS X only).- Since:
- 1.0.3
