readKeywords

public static void readKeywords(org.antlr.v4.runtime.Vocabulary vocab,
 int startId,
 int endId,
 Map<String,KeywordCategory> keywords,
 KeywordCategory type)

Reads a range of token IDs from a vocabulary and populates a keyword map with the specified category. This is a utility method for initializing keyword maps based on lexer token definitions.

Parameters:

vocab - the vocabulary containing token literal names

startId - the starting token (inclusive)

endId - the ending token(inclusive)

keywords - the map to populate with keywords and their categories

type - the category to assign to all keywords in the specified range
