org.apache.directory.shared.ldap.model.cursor.Cursor
A Cursor for bidirectional traversal over elements in a dataSet. Cursors unlike Iterators or Enumerations may advance to an element by calling next() or previous() which returns true or false if the request succeeds with a viable element at the new position. Operations for relative positioning in larger increments are provided. If the cursor can not advance, then the Cursor is either positioned before the first element or after the last element in which case the user of the Cursor must stop advancing in the respective direction. If an advance succeeds a get() operation retrieves the current object at the Cursors position. Although this interface presumes Cursors can advance bidirectionally, implementations may restrict this by throwing UnsupportedOperationExceptions. @author Apache Directory Project @param < E> The type of element on which this cursor will iterate
