java.lang.Object

io.hypersistence.utils.hibernate.type.ImmutableType<T>

io.hypersistence.utils.hibernate.type.DescriptorImmutableType<T,JDBC,JAVA>

All Implemented Interfaces:

Serializable, org.hibernate.query.BindableType<T>, org.hibernate.query.sqm.SqmExpressible<T>, org.hibernate.type.Type, org.hibernate.usertype.EnhancedUserType<T>, org.hibernate.usertype.UserType<T>

Direct Known Subclasses:

CurrencyUnitType, Iso8601MonthType, MonthDayDateType, MonthDayIntegerType, YearMonthDateType, YearMonthEpochType, YearMonthIntegerType, YearMonthTimestampType, YearType, ZoneIdType

public abstract class DescriptorImmutableType<T,JDBC extends org.hibernate.type.descriptor.jdbc.JdbcType,JAVA extends org.hibernate.type.descriptor.java.JavaType<T>>
extends ImmutableType<T>
implements org.hibernate.query.BindableType<T>, org.hibernate.query.sqm.SqmExpressible<T>

Very convenient base class for implementing immutable object types using Hibernate UserType using the JdbcType and JavaType descriptors.
