Class PowerQueryTokenCodes

Object

gudusoft.gsqlparser.parser.powerquery.PowerQueryTokenCodes

public final class PowerQueryTokenCodes
extends Object

Power Query M-Language token codes.

Isolated from TBaseType to avoid reshuffling existing vendor token values when Power Query support is added. Codes here start at 2000 (well above all existing base codes and well below any vendor-reserved range).

The sentinel PQ_TOKEN_BASE = 2000 gives 96 slots for M-specific tokens which is generous even for a full Tier 3 grammar.
