java.lang.Objectorg.apache.cayenne.access.types.ByteType
public class ByteType
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).
