What Is A View Cursor?

Answer»

A CURSOR is a position INDICATOR; it POINTS to a particular item in the collection. We use view cursor to traverse items in a collection’s data view and modify the data in collection.

A view cursor INCLUDES following methods:

  1. The moveNext() and movePrevious() to move the cursor forward or backward. Use beforeFirst or afterLast properties to check WHETHER we have reached the bounds.
  2. The findAny(), findFirst() and findLast() methods move the cursor to an item that matches the parameter.
