Interface RowSetIterator

All Known Subinterfaces:

RowSet, ViewObject

All Known Implementing Classes:

ViewRowSetIteratorImpl

public interface RowSetIterator

extends RowIterator

Provides simple access to a set of rows.

View Object methods may use row set iterators to navigate through a row set resulting from a query. Row set iterators provide a window into the row set, making a subset of it accessible. Each row of the row set is represented by a Row object.

JDeveloper 3.0
