public class DateFormatParser
extends java.lang.Object

Base class for Progress date format parsers/formatters. The parse(String) method is responsible for checking the Progress date format validity. Also this class provides a set of callback methods, each callback is called when the corresponding format component is parsed. By default, all callbacks do nothing, they are expected to be re-defined in subclasses.

Parameters:

sep - the second separator character

visitDateComponent

protected void visitDateComponent(int componentIndex,
                                  int startIdx,
                                  int endIdx)

Dispatch the date component to a matching callback.

Parameters:

componentIndex - the number of the component in the format spec
