    • isAssociationType

      public final boolean isAssociationType()
      Description copied from interface: Type

      True if this type is also an AssociationType implementor; false otherwise.

    • isCollectionType

      public final boolean isCollectionType()
      Description copied from interface: Type

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

      Specified by:

      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 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
      Returns:
      The hash code

    • getHashCode

      public final int getHashCode(Object x, SessionFactoryImplementor factory)
      Description copied from interface: Type

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

      Should the parent be considered dirty, given both the old and current value?
      Specified by:
      isDirty in interface Type
      Parameters:
      old - the old value
      current - the current value
      session - The session from which the request originated.
      Returns:
      true if the field is dirty

    • isDirty

      public final boolean isDirty(Object old, Object current, boolean[] checkable, SharedSessionContractImplementor session)
      Description copied from interface: Type
      Should the parent be considered dirty, given both the old and current value?
      Specified by:
      isDirty in interface Type
      Parameters:
      old - the old value
      current - the current value
      checkable - An array of booleans indicating which columns making up the value are actually checkable
      session - The session from which the request originated.
      Returns:
      true if the field is dirty

    • isDirty

      protected final boolean isDirty(Object old, Object current)

    • isModified

      public final boolean isModified(Object oldHydratedState, Object currentState, boolean[] checkable, SharedSessionContractImplementor session)
      Description copied from interface: Type
      Has the value been modified compared to the current database state? The difference between this and the Type.isDirty(java.lang.Object, java.lang.Object, org.hibernate.engine.spi.SharedSessionContractImplementor) methods is that here we need to account for "partially" built values. This is really only an issue with association types. For most type implementations it is enough to simply delegate to Type.isDirty(java.lang.Object, java.lang.Object, org.hibernate.engine.spi.SharedSessionContractImplementor).
      Specified by:
      isModified in interface Type
      Parameters:
      oldHydratedState - the database state, in a "hydrated" form, with identifiers unresolved
      currentState - the current state of the object
      checkable - which columns are actually checkable
      session - The session from which the request originated.
      Returns:
      true if the field has been modified

      cached - the disassembled state from the cache
      session - the originating session

      public final Serializable disassemble(Object value, SharedSessionContractImplementor session, Object owner) throws HibernateException
      Description copied from interface: Type
      Return a disassembled representation of the object. This is the representation that is stored in the second-level cache.

      A reference to an associated entity should be disassembled to its primary key value.

      Specified by:
      disassemble in interface Type
      Parameters:
      value - the value to cache
      session - the originating session

    • disassemble

      public Object disassemble(Object value, SharedSessionContractImplementor session)
      Description copied from interface: Bindable
      Breaks down a value of J into its simple pieces. E.g., an embedded value gets broken down into an array of its attribute state; a basic value converts to itself; etc.

      Generally speaking, this is the form in which entity state is kept relative to a Session via EntityEntry. 

       @Entity class Person {
     @Id Integer id;
     @Embedded Name name;
     int age;
 }

 @Embeddable class Name {
     String familiarName;
     String familyName;
 }

      At the top level, we would want to disassemble a Person value, so we'd ask the Bindable for the Person entity to disassemble. Given a Person value: 

       Person( id=1, name=Name( 'Steve', 'Ebersole' ), 28 )

      this disassemble would result in a multidimensional array: 

       [ ["Steve", "Ebersole"], 28 ]

      Note that the identifier is not part of this disassembled state. Note also how the embedded value results in a sub-array.

      disassemble in interface BasicType<J>

      disassemble in interface BasicValuedMapping
