    • Method Detail

      • isEntityType

        public final boolean isEntityType()
        Explicitly, an entity type is an entity type ;)
        Specified by:
        isEntityType in interface Type
        Overrides:
        isEntityType in class AbstractType
        Returns:
        True.

      • isMutable

        public boolean isMutable()
        Description copied from interface: Type
        Are objects of this type mutable with respect to the referencing object? Entities and collections are considered immutable because they manage their own internal state.
        Specified by:
        isMutable in interface Type
        Returns:
        boolean

      • toString

        public String toString()
        Generates a string representation of this type.
        Overrides:
        toString in class Object
        Returns:
        string rep

      • getName

        public String getName()
        For entity types, the name correlates to the associated entity name.
        Specified by:
        getName in interface Type
        Returns:
        the Hibernate type name

      • isReferenceToPrimaryKey

        public boolean isReferenceToPrimaryKey()
        Does this association foreign key reference the primary key of the other table? Otherwise, it references a property-ref.
        Returns:
        True if this association reference the PK of the associated entity.

      • getRHSUniqueKeyPropertyName

        public String getRHSUniqueKeyPropertyName()
        Description copied from interface: AssociationType
        The name of a unique property of the associated entity that provides the join key (null if the identifier of an entity, or key of a collection)
        Specified by:
        getRHSUniqueKeyPropertyName in interface AssociationType

      • getLHSPropertyName

        public String getLHSPropertyName()
        Description copied from interface: AssociationType
        Get the name of a property in the owning entity that provides the join key (null if the identifier)
        Specified by:
        getLHSPropertyName in interface AssociationType

      • getPropertyName

        public String getPropertyName()

      • getAssociatedEntityName

        public final String getAssociatedEntityName()
        The name of the associated entity.
        Returns:
        The associated entity name.

      • getReturnedClass

        public final Class<?> getReturnedClass()
        This returns the wrong class for an entity with a proxy, or for a named entity. Theoretically it should return the proxy class, but it doesn't.

        The problem here is that we do not necessarily have a ref to the associated entity persister (nor to the session factory, to look it up) which is really needed to "do the right thing" here...

        Specified by:
        getReturnedClass in interface Type
        Returns:
        The entity class.

      • nullSafeSet

      • replace

        public Object replace​(Object original,
                      Object target,
                      SharedSessionContractImplementor session,
                      Object owner,
                      Map<Object,​Object> copyCache)
               throws HibernateException
        Description copied from interface: Type
        During merge, replace the existing (target) value in the entity we are merging to with a new (original) value from the detached entity we are merging. For immutable objects, or null values, it is safe to simply return the first parameter. For mutable objects, it is safe to return a copy of the first parameter. For objects with component values, it might make sense to recursively replace component values.
        Specified by:
        replace in interface Type
        Parameters:
        original - the value from the detached entity being merged
        target - the value in the managed entity
        session - The originating session
        owner - The owner of the value
        copyCache - The cache of already copied/replaced values
        Returns:
        the value to be merged
        Throws:
        HibernateException - An error from Hibernate

      • isEqual

        public boolean isEqual​(Object x,
                       Object y,
                       SessionFactoryImplementor factory)
        Description copied from interface: Type
        Compare two instances of the class mapped by this type for persistence "equality", that is, equality of persistent state. For most types this could simply delegate to Type.isEqual(Object, Object).

        This should always equate to some form of comparison of the value's internal state. As an example, for Java's Date class, the comparison should be of its internal state, but based only on the specific part which is persistent (the timestamp, date, or time).

        Specified by:
        isEqual in interface Type
        Overrides:
        isEqual in class AbstractType
        Parameters:
        x - The first value
        y - The second value
        factory - The session factory
        Returns:
        True if there are considered equal (see discussion above).

      • isEager

        Parameters:
        overridingEager - can override eager from the mapping.
        Returns:
        If overridingEager is null, then it does not override. If true or false then it overrides the mapping value.
