Class SimpleDateMatcher

java.lang.Object

com.cobber.fta.SimpleDateMatcher

public class SimpleDateMatcher
extends java.lang.Object

Helper class to manage several of the fixed length date inputs. Used to match from an internal normalized form to a Java DateTimeFormatter. Vector returned is: DayOffset DayLength MonthOffset MonthLength YearOffset YearLength Offsets can be positive from the start of the string, or negative from the end of the string Lengths can be positive which reflects true length or negative field separated Note: Currently the set of string supported does not depend on the Locale supplied. Need to survey additional languages to identify whether this is necessary or not.

public SimpleDateMatcher(java.lang.String input,
                         java.util.Locale locale)

Construct the SimpleDateMatcher for this input (if possible).

Parameters:

input - The input to be parsed

locale - The Locale we are currently processing

Method Detail

getType

public static PatternInfo.Type getType(java.lang.String pattern,
                                       java.util.Locale locale)

compress

public static java.lang.String compress(java.lang.String input,
                                        java.util.Locale locale)

'Compress' the input string (which we think represents a date) so that it can be matched in the list of predefined formats. Mapping:

• Trailing AM/PM replaced with P
• Strings of digits replaced by d{n} for n > 1, or d for n = 1
• Strings of alphas replaced by a{4} for n > 4, a{n} for n > 1 and n < 4, or a for n = 1

Parameters:

input - The input string to be matched

locale - The Locale the date String is in

Returns:

The compressed representation
