Class ImmutableType<T>

java.lang.Object
  extended by com.vladmihalcea.hibernate.type.ImmutableType<T>
All Implemented Interfaces:
Serializable, org.hibernate.type.Type, org.hibernate.usertype.UserType
Direct Known Subclasses:
NullableCharacterType, PostgreSQLCITextType, PostgreSQLGuavaRangeType, PostgreSQLHStoreType, PostgreSQLInetType, PostgreSQLRangeType, PostgreSQLTSVectorType
public abstract class ImmutableType<T>
extends Object
implements org.hibernate.usertype.UserType, org.hibernate.type.Type

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 SQLQuery.addScalar(String, Type) method to fix the No Dialect mapping for JDBC type issues.
