Interface RowIterator

All Superinterfaces:

java.util.Iterator<Column>

public interface RowIterator
extends java.util.Iterator<Column>

RowIterator objects allow a program to iterate over the column names of a Row.

When you do not know the columns of a row at the time you design a program, your program can use a row iterator to traverse the columns of a row.

A row iterator presents all the columns that are actually set in a row object. The table schema determines the order in which an iterator presents the columns of a row.

Row iterator objects are not thread-safe. Programs must not access a row iterator from several threads simultaneously.

To create a RowIterator object, call Row.iterator.

This interface is implemented internally. Applications do not implement this interface.
