Methods
-
advance(
[int distance = 1]) → Token -
Advance till reach
distance, return the token at original position. -
expect(
List< String> types, {bool consume = false}) → bool -
Check current token and some tokens after it to see if the
typesmatch, return a boolean result. Ifconsumeis true, will advance. -
match(
String type) → Token -
If the token match the
typeprovided, advance 1 and return the original token. If not, generate an error. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
peek(
int distance) → Token -
Get a token at a relative
distancefrom current position. -
seek(
String type) → Token - Search for a token type, return the token next to it.
-
seekGroupClosing(
Map< String, String> groupClosings) → Token - Search for parentheses end that can close the current one, return the token next to it.
-
setTokens(
{required Token token, int? line, int? column}) → void - Set current tokens.
