Class ByteType

java.lang.Object
org.apache.cayenne.access.types.ByteType
All Implemented Interfaces:
ExtendedType<Byte>

public class ByteType
extends Object
implements ExtendedType<Byte>
Handles java.lang.Byte type 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).
