      • 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. Shortcut for type instanceof AssociationType.
        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. Shortcut for type instanceof CompositeType.

        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. Shortcut for type instanceof EntityType.

        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. Shortcut for type instanceof AnyType.

        An AnyType is additionally an AssociationType; so if this method returns true, then 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", that is, equality of persistent state, taking a shortcut for entity references.

        For most types this should boil down to an equality comparison of the given values, and it's reasonable to simply delegate to Type.isEqual(Object, Object). But for associations the semantics are a bit different.

        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", 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
        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", that is, equality of persistent state. For most types this could simply delegate to equals().

        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
        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". For most types this could simply delegate to the given value's hashCode.
        Specified by:
        getHashCode in interface Type
        Parameters:
        x - The value for which to retrieve a hash code

        Parameters:
        x - The value for which to retrieve a hash code

        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.
