---

public class ResultSetIterator

extends java.lang.Object

implements DynaBean, java.util.Iterator

Implementation of java.util.Iterator returned by the iterator() method of ResultSetDynaClass. Each object returned by this iterator will be a DynaBean that represents a single row from the result set being wrapped.

protected  ResultSetDynaClass	dynaClass           The ResultSetDynaClass we are associated with.
protected  boolean	eof           Flag indicating whether the result set has indicated that there are no further rows.

 

Constructor Summary
(package private)	ResultSetIterator(ResultSetDynaClass dynaClass)           Construct an Iterator for the result set being wrapped by the specified ResultSetDynaClass.

 

Method Summary
protected  void	advance()           Advance the result set to the next row, if there is not a current row (and if we are not already at eof).
