Extend an operator class

These topics describe how to extend the functionality of operator classes. An operator class is the set of functions that is associated with a secondary-access method. The database server provides two ways to extend operator classes:
  • Extensions of operator classes that the database server provides

    When you want to order the data in a different sequence or provide index support for a UDT, you must extend an operator class.

  • User-defined operator classes

    When one of the existing secondary-access methods cannot easily index a UDT, you might need to create a new operator class.
