IList

The IList interface describes the methods available from a Java class when accessing an Sites query or list object. It also defines the methods that a third party must implement when attempting to construct and register a list object for use within an Sites XML page.

Each element of the list consists of an ordered set of named columns, numbered from 0 (zero) to n-1, where n is the number of columns. The order of elements in the list does not correspond to the order of the select list expressions in a SQL query, if the IList object is returned as a result of a SQL query execution.

Note In an IList, rows are numbered from 1 to M; columns are numbered from 0 to N-1.
