DEFAULT_CHANNEL enum int DEFAULT_CHANNEL;: @uml All tokens go to the parser (unless skip() is called in that rule) on a particular "channel". The parser tunes to a particular channel so that whitespace etc... can go to the parser on a "hidden" channel.
EOF enum int EOF;: Undocumented in source.
EPSILON enum int EPSILON;: @uml During lookahead operations, this "token" signifies we hit rule end ATN state and did not follow it despite needing to.
HIDDEN_CHANNEL enum int HIDDEN_CHANNEL;: @uml Anything on different channel than DEFAULT_CHANNEL is not parsed by parser.
INVALID_TYPE enum int INVALID_TYPE;: Undocumented in source.
MIN_USER_CHANNEL_VALUE enum int MIN_USER_CHANNEL_VALUE;: @uml This is the minimum constant value which can be assigned to a ser-defined token channel.
MIN_USER_TOKEN_TYPE enum int MIN_USER_TOKEN_TYPE;: Undocumented in source.
