      Description copied from interface: Type
      Bind a value represented by an instance of the mapped class to the given JDBC PreparedStatement, 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.

      value - the object to write
      index - starting parameter bind index
      session - The originating session

      HibernateException - An error from Hibernate
      SQLException - An error from the JDBC driver

      Deprecated, for removal: This API element is subject to removal in a future version.
      Description copied from interface: Type
      Bind a value represented by an instance of the mapped class to the given JDBC PreparedStatement, 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.
      Parameters:
      st - The JDBC prepared statement to which to bind
      value - the object to write
      index - starting parameter bind index
      settable - an array indicating which columns to bind/ignore

      Return a deep copy of the persistent state, stopping at entities and at collections.
      Parameters:
      value - The value to be copied

    • replace

      public Object replace(Object original, Object target, SharedSessionContractImplementor session, Object owner, Map<Object,Object> copyCache)
      Deprecated, for removal: This API element is subject to removal in a future version.
      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.
      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:
      the value to be merged

      Deprecated, for removal: This API element is subject to removal in a future version.
      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.
      Returns:
      boolean

    • toColumnNullness

      public boolean[] toColumnNullness(Object value, Mapping mapping)
      Deprecated, for removal: This API element is subject to removal in a future version.
      Description copied from interface: Type
      Given an instance of the type, return an array of boolean values indicating which mapped columns would be null.
      Parameters:
