eu.bandm.tscore.base.Translet.Alternative

Enclosing class:

Translet

protected static class Translet.Alternative
extends Object

Realizes a protocol tree of alternatives to the parsing results. An instance is newly constructed for every unsuccessful attempt to apply a particular parser in a particular state. (In method Translet.Parser.mparse(Set,Set).) This is meant as a diagnostic hint for the (domain expert) user, at which earlier positions in the input a possible parser had been missed and where thus a typo/mis-spelling in the input data could have happened. The set of alteratives is passed in parallel to the current (valid) input state, and when testing the subsequent parsers, these will not only be tested but also be appended to expected by calling append(Translet.Parser).
