类 TinyIntTypeDescriptor

java.lang.Object

org.hibernate.type.descriptor.sql.TinyIntTypeDescriptor

所有已实现的接口:

Serializable, SqlTypeDescriptor

public class TinyIntTypeDescriptor
extends Object
implements SqlTypeDescriptor

Descriptor for TINYINT handling.

Note that JDBC states that TINYINT should be mapped to either byte or short, but points out that using byte can in fact lead to loss of data.
