Interface PositionedIterator

public abstract interface PositionedIterator

extends ResultSetIterator

An interface implemented by all iterators that employ a by-position binding strategy. All such iterators depend on the position of the columns of the data to which they are bound, as opposed to the names of the columns to which they are bound.

In addition to implementing this interface, position-bound iterator implementations will provide:

• A public constructor which takes an RTResultSet as a parameter. If the construction of a positioned iterator results in an exception being thrown, it is assumed that the iterator automatically closes the underlying result set. This only applies to exceptions thrown during construction.
• An accessor method for each column in the expected result. The name of the accessor method for the Nth column will be getColN.
