        Use EntityType(org.hibernate.type.TypeFactory.TypeScope, String, boolean, String, boolean, boolean) instead.
        Constructs the requested entity type mapping.
        Parameters:
        scope - The type scope
        entityName - The name of the associated entity.
        uniqueKeyPropertyName - The property-ref name, or null if we reference the PK of the associated entity.
        eager - Is eager fetching enabled.
        unwrapProxy - Is unwrapping of proxies allowed for this association; unwrapping says to return the "implementation target" of lazy prooxies; typically only possible with lazy="no-proxy".

      • isEntityType

        public final boolean isEntityType()
        Explicitly, an entity type is an entity type ;)
        Specified by:

        Overrides:
        isEntityType in class AbstractType
        Returns:

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

      • getName

        public java.lang.String getName()
        For entity types, the name correlates to the associated entity name.
        Specified by:

        Returns:
        String 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 java.lang.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 java.lang.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 java.lang.String getPropertyName()

      • getAssociatedEntityName

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

      • getReturnedClass

        public final java.lang.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 entiyt class.

        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.

        Overrides:
        getHashCode in class AbstractType

                       SessionFactoryImplementor factory)
        Description copied from interface: Type
        Compare two instances of the class mapped by this type for persistence "equality" (equality of persistent state).

        This should always equate to some form of comparison of the value's internal state. As an example, for something like a date the comparison should be based on its internal "time" state based on the specific portion it is meant to represent (timestamp, date, time).

        Specified by:
        isEqual in interface Type
        Overrides:
        isEqual in class AbstractType
        Parameters:

        y - The second value
        factory - The session factory
