Class MaskConverter<C>

java.lang.Object

org.apache.wicket.util.convert.MaskConverter<C>

Type Parameters:

C -

All Implemented Interfaces:

Serializable, IConverter<C>, IClusterable

public class MaskConverter<C>
extends Object
implements IConverter<C>

A converter that takes a mask into account. It is specifically meant for overrides on individual components, that provide their own converter by returning it from Component#getConverter(Class). It uses an instance of MaskFormatter to delegate the masking and unmasking to.

The following characters can be specified (adopted from the MaskFormatter documentation):

Character	Description
#	Any valid number, uses Character.isDigit.
'	Escape character, used to escape any of the special formatting characters.
U	Any character (Character.isLetter). All lowercase letters are mapped to upper case.
L	Any character (Character.isLetter). All upper case letters are mapped to lower case.
A	Any character or number (Character.isLetter or Character.isDigit)
?	Any character (Character.isLetter).
	Anything.
H	Any hex character (0-9, a-f or A-F).

Typically characters correspond to one char, but in certain languages this is not the case. The mask is on a per character basis, and will thus adjust to fit as many chars as are needed.
