Any meaning in the grouping parens in ANTLR

Are the following two rules the same in ANTLR4, or does using a parens give any additional grouping information or such, similar to a regex capturing group:

WS  : (' '|'\t'|'\r'|'\n')+ -> skip;

WS  : [ \t\r\n]+ -> skip;

>Solution :

Those are synonymous. The latter is just a more concise syntax for the former.
