Class CharClass

java.lang.Object

com.google.re2j.CharClass

class CharClass
extends Object

A "builder"-style helper class for manipulating character classes represented as an array of pairs of runes [lo, hi], each denoting an inclusive interval. All methods mutate the internal state and return this, allowing operations to be chained.
