java.lang.Object
  com.acsinet_solutions.cetia4.controller.support.ParameterIterator

public final class ParameterIterator
extends java.lang.Object

A parameter iterator instance. This is a java.sql.ResultSet style iterator, instead of a java.util.Iterator one. A perl 5 regular expression is passed to the constructor of this object to decide which parameters are of interest for this iterator ( only paraemters that match the regexp will be considered ). The regular expression must contain at least one matching section ( in parentheses ). In that matching section, a result will be provided of the types that are passed as arguments of the constructors.
