Method Details

and

RE.C and(RE.C and)

Intersect two character classes. This uses the `invalid input: '&'invalid input: '&'` operator. I.e. `[%abc@]` and `\p{Alnum}` will intersect to only `abc` and will be represented as `[abcinvalid input: '&'invalid input: '&'\p{Alnum}`.

Parameters:

and - the second character class

Returns:

a new character class

or

RE.C or(RE.C or)

Make the union of two character classes. This concatenates the set if possible. I.e. `[%abc@]` and `\p{Alnum}` will union to `[%abc@\p{Alnum}]`.

Parameters:

or - the second character class

Returns:

a new character class

or

default RE.C or(String or)

Make the union of two character classes. This concatenates the set if possible. I.e. `[%abc@]` and `\p{Alnum}` will union to `[%abc@\p{Alnum}]`.

Parameters:

or - the second character class

Returns:

a new character class

asSetContent

String asSetContent()

Return just the content of the set without the square brackets.

not

RE.C not()

Some character sets have a reverse name. For example the `\s` has `\S`. A set with square brackets can be reversed by adding/removing a `^` as first character. This overrides the RE version but returns a C so this can be repeated.
