| The ''is()'' method allows checking for certain tokens, while abstracting over whether it is a single-char token ''%%$token->is(';')%%'', a multi-char token ''%%$token->is(T_FUNCTION)%%'', or whether multiple tokens are allowed ''%%$token->is([T_CLASS, T_TRAIT, T_INTERFACE])%%''. | The ''is()'' method allows checking for certain tokens, while abstracting over whether it is a single-char token ''%%$token->is(';')%%'', a multi-char token ''%%$token->is(T_FUNCTION)%%'', or whether multiple tokens are allowed ''%%$token->is([T_CLASS, T_TRAIT, T_INTERFACE])%%''. |

| While non-generic code can easily check the appropriate property, such as ''%%$token->text == ';'%%'' or ''%%$token->id == T_FUNCTION%%'', token stream implementations commonly need to be generic over different token kinds and need to support specification of multiple token kind.
