Class ShortType

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

public class ShortType
extends Object
implements ExtendedType<Short>
Handles java.lang.Short type mapping. Can be configured to recast java.lang.Short 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 short values are Sybase and Oracle (Mac OS X only).
