Class TRegular.Characters

java.lang.Object

org.stekikun.dolmen.tagged.TRegular

org.stekikun.dolmen.tagged.TRegular.Characters

Enclosing class:

TRegular

public static final class TRegular.Characters
extends TRegular

Instances of regular expressions that match exactly one character amongst a set of possible characters. The character set is described by an integer index in some external character set map. Can also match the end-of-input via a special character set, in which case TRegular.size will be 0 and not 1. If eof is false, then chars cannot contain the end-of-input marker; if eof is true, then chars must only contain the end-of-input marker.
