Class ImmutableType<T>

java.lang.Object

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

All Implemented Interfaces:

Serializable, org.hibernate.type.BasicType, org.hibernate.type.Type, org.hibernate.usertype.UserType

Direct Known Subclasses:

NullableCharacterType, OracleIntervalDayToSecondType, PostgreSQLCITextType, PostgreSQLGuavaRangeType, PostgreSQLHStoreType, PostgreSQLInetType, PostgreSQLIntervalType, PostgreSQLLTreeType, PostgreSQLPeriodType, PostgreSQLRangeType

public abstract class ImmutableType<T>
extends Object
implements org.hibernate.usertype.UserType, org.hibernate.type.BasicType

Very convenient base class for implementing immutable object types using Hibernate UserType.

The ImmutableType implements the Type interface too, so you can pass all types extending the ImmutableType to the NativeQuery.addScalar(String, Type) method to fix the No Dialect mapping for JDBC type issues.
