Types

type CharacterClass 

type CharacterClass struct {
	// contains filtered or unexported fields
}

CharacterClass implements a char token which holds a pattern of characters and character classes Each character class characters is added to the set of characters of the token. Every permutations chooses one character out of the available set of characters as the current value of the token.
