public class DatetimeFormatParser
extends DateFormatParser

Base class for Progress datetime/datetime-tz format parsers/formatters. The parse(String) method is responsible for checking the Progress datetime/datetime-tz 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.

Method Detail

visitHours

protected void visitHours(int startIdx,
                          int endIdx)

The hours component of the date spec was parsed.

Parameters:

startIdx - the component start index, zero based

endIdx - the component end index, zero based, exclusive. The end index is always greater than the start index.

                            int endIdx)

The minutes component of the date spec was parsed.

Parameters:

startIdx - the component start index, zero based

endIdx - the component end index, zero based, exclusive. The end index is always greater than the start index.

visitSeconds

protected void visitSeconds(int startIdx,
                            int endIdx)

The seconds component of the date spec was parsed.

Parameters:

startIdx - the component start index, zero based

endIdx - the component end index, zero based, exclusive. The end index is always greater than the start index.

visitMilliseconds

protected void visitMilliseconds(int startIdx,
                                 int endIdx)

The milliseconds component of the date spec was parsed.

Parameters:

startIdx - the component start index, zero based

endIdx - the component end index, zero based, exclusive. The end index is always greater than the start index.

visitAMPM

protected void visitAMPM(int startIdx,
                         int endIdx)

The AM component of the date spec was parsed.

Parameters:

startIdx - the component start index, zero based

endIdx - the component end index, zero based, exclusive. The end index is always greater than the start index.

visitTZHours

protected void visitTZHours(int startIdx,
                            int endIdx)

The hours in timezone component of the date spec was parsed.

Parameters:

startIdx - the component start index, zero based

endIdx - the component end index, zero based, exclusive. The end index is always greater than the start index.

visitTZMinutes

protected void visitTZMinutes(int startIdx,
                              int endIdx)

The minutes in timezone component of the date spec was parsed.

Parameters:

startIdx - the component start index, zero based

endIdx - the component end index, zero based, exclusive. The end index is always greater than the start index.
