Interface CharCaseFolding

A set of functions that can be used to perform case-insensitive matching.

It must fulfill the following conditions:

canonicalize must be idempotent, i.e. canonicalize(canonicalize(char)) === canonicalize(char).
toCharSet(canonicalize(a)) is the set of all characters c such that canonicalize(a) === canonicalize(c).

Properties

`Optional` `Readonly` canonicalize

canonicalize?: ((char: Char) => Char)

Type declaration

- (char: Char): Char
- The canonicalization function. This typically maps characters to their lowercase form.
  
  If no function is given, then the identity function is used. This also implies that toCharSet must return a set containing only the given character.
  Parameters
  - char: Char
  Returns Char
  Default
```
char => char
```

`Readonly` toCharSet

toCharSet: ((char: Char) => CharSet)

Type declaration

- (char: Char): CharSet
- Parameters
  - char: Char
  Returns CharSet
