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 {@link Component#getConverter(Class)}. It uses an instance of {@link MaskFormatter} to delegatethe 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.
