public class DbIterator

extends java.lang.Object

implements java.util.Iterator

An iterator class for DbTables. There is no public constructor. Use DbTable.iterator(). While this class supports the java.util.Iterator interface, it is recommended not to use it because they do not throw the proper DbException on error. Instead use the similar hasNextRow() and nextRow().

boolean	hasNextRow() Are there more rows to iterator through?
java.lang.Object	next() Returns the next item.
