Methods
-
getDisplayName(
int tokenType) → String -
Gets the display name of a token type.
override
-
getLiteralName(
int tokenType) → String? -

by this method, when not null, can be used unaltered in a parser
grammar to represent this token type.
override
-
getSymbolicName(
int tokenType) → String? -
Gets the symbolic name associated with a token type. The string returned
by this method, when not null, can be used unaltered in a parser
grammar to represent this token type.

Static Methods
-
fromTokenNames(
List< String?> ? tokenNames) → Vocabulary -

names. This method acts as a compatibility layer for the single
tokenNamesarray generated by previous releases of ANTLR.
