      • getColumnSpan

        public final int getColumnSpan​(Mapping mapping)
                        throws MappingException
        Description copied from interface: Type
        How many columns are used to persist this type. Always the same as sqlTypes(mapping).length
        Specified by:
        getColumnSpan in interface Type

        mapping - The mapping object :/
        Returns:
        The number of columns

      • isAssociationType

        public final boolean isAssociationType()
        Description copied from interface: Type
        Return true if the implementation is castable to AssociationType. This does not necessarily imply that the type actually represents an association. Essentially a polymorphic version of (type instanceof AssociationType.class)
        Specified by:
        isAssociationType in interface Type
        Returns:
        True if this type is also an AssociationType implementor; false otherwise.

      • isComponentType

        public final boolean isComponentType()
        Description copied from interface: Type
        Return true if the implementation is castable to CompositeType. Essentially a polymorphic version of (type instanceof CompositeType.class). A component type may own collections or associations and hence must provide certain extra functionality.
        Specified by:
        isComponentType in interface Type
        Returns:
        True if this type is also a CompositeType implementor; false otherwise.

      • isEntityType

        public final boolean isEntityType()
        Description copied from interface: Type
        Return true if the implementation is castable to EntityType. Essentially a polymorphic version of (type instanceof EntityType.class).

        An EntityType is additionally an AssociationType; so if this method returns true, Type.isAssociationType() should also return true.

        Specified by:
        isEntityType in interface Type
        Returns:
        True if this type is also an EntityType implementor; false otherwise.

      • isAnyType

        public final boolean isAnyType()
        Description copied from interface: Type
        Return true if the implementation is castable to AnyType. Essentially a polymorphic version of (type instanceof AnyType.class).

        An AnyType is additionally an AssociationType; so if this method returns true, Type.isAssociationType() should also return true.

        Specified by:
        isAnyType in interface Type
        Returns:
        True if this type is also an AnyType implementor; false otherwise.

      • isSame

        public final boolean isSame​(Object x,
                            Object y)
        Description copied from interface: Type
        Compare two instances of the class mapped by this type for persistence "equality" (equality of persistent state) taking a shortcut for entity references.

        For most types this should equate to an equals check on the values. For associations the implication is a bit different. For most types it is conceivable to simply delegate to Type.isEqual(java.lang.Object, java.lang.Object)

        Specified by:
        isSame in interface Type
        Parameters:
        x - The first value
        y - The second value
        Returns:
        True if there are considered the same (see discussion above).

      • isEqual

        public final 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" (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
        Parameters:
        x - The first value
        y - The second value
        factory - The session factory
        Returns:
        True if there are considered equal (see discussion above).

      • isEqual

        public boolean isEqual​(Object one,
                       Object another)
        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
        Parameters:
        one - The first value
        another - The second value
        Returns:
        True if there are considered equal (see discussion above).

      • getHashCode

        public final int getHashCode​(Object x)
        Description copied from interface: Type
        Get a hash code, consistent with persistence "equality". Again for most types the normal usage is to delegate to the value's hashCode.
        Specified by:
        getHashCode in interface Type
        Parameters:
        x - The value for which to retrieve a hash code

        public final int getHashCode​(Object x,
                             SessionFactoryImplementor factory)
        Description copied from interface: Type
        Get a hash code, consistent with persistence "equality". Again for most types the normal usage is to delegate to the value's hashCode.

                         Object y)
        Description copied from interface: Type
        Perform a Comparator style comparison between values
        Specified by:
        compare in interface Type
        Parameters:
        x - The first value
        y - The second value
        Returns:
        The comparison result. See Comparator.compare(T, T) for a discussion.

        public final 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.)

                            Map<Object,​Object> copyCache)
        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:

        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:

        Description copied from interface: Type
        Bind a value represented by an instance of the mapped class to the JDBC prepared statement, ignoring some columns as dictated by the 'settable' parameter. Implementors should handle the possibility of null values. A multi-column type should bind parameters starting from index.
