Direct Known Subclasses:

Translet.OrLimesParser, Translet.PriorLimesParser

Enclosing class:

Translet

public abstract static class Translet.LimesParser<A>
extends Translet.DisjunctionParser<A>

Common superclass for Parsers which accept one of many alternatives and return the upper limit of the different result classes (OR1 and PRIOR1). Currently maximally four(4) sub-parsers are supported.
There are four flavours of disjunctions: Acceptance can follow a priority, or be nondeterministic; the result can be a common superclass, or a CoTuple.
