Details

Base class for "direction" productions. Each direction (the compass directions, the vertical directions, the shipboard directions, and so on) must have an associated grammar rule, which must produce one of these. This should be subclassed with grammar rules like this:

grammar directionName: 'north' | 'n' : DirectionProd
dir = northDirection
;

class DirectionProd : BasicProd
