      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:

      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
      Returns:

    • getHashCode

      public final int getHashCode(Object x, SessionFactoryImplementor factory)

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

      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
