OVERLOADED_OPERATOR is used for single-token operators 21 /// (e.g., "+"), and has six arguments: 22 /// 23 /// Name: The name of the token. OO_Name will be the name of the 24 /// corresponding enumerator in OverloadedOperatorKind in 25 /// OperatorKinds.h. 26 /// 27 /// Spelling: A string that provides a canonical spelling for the 28 /// operator, e.g., "operator+". 29 /// 30 /// Token: The name of the token that specifies the operator, e.g., 31 /// "plus" for operator+ or "greatergreaterequal" for 32 /// "operator>>=". With a "kw_" prefix, the token name can be used as 33 /// an enumerator into the TokenKind enumeration. 34 /// 35 /// Unary: True if the operator can be declared as a unary operator. 36 /// 37 /// Binary: True if the operator can be declared as a binary 38 /// operator. Note that some operators (e.g., "operator+" and 39 /// "operator*") can be both unary and binary. 40 /// 41 /// MemberOnly: True if this operator can only be declared as a 42 /// non-static member function. False if the operator can be both a 43 /// non-member function and a non-static member function. 44 /// 45 /// OVERLOADED_OPERATOR_MULTI is used to enumerate the multi-token 46 /// overloaded operator names, e.g., "operator delete []". The macro 47 /// has all of the parameters of OVERLOADED_OPERATOR except Token, 48 /// which is omitted. 49 50 #ifndef OVERLOADED_OPERATOR 51 # define OVERLOADED_OPERATOR(Name,Spelling,Token,Unary,Binary,MemberOnly) 52 #endif 53 54 #ifndef OVERLOADED_OPERATOR_MULTI 55 # define OVERLOADED_OPERATOR_MULTI(Name,Spelling,Unary,Binary,MemberOnly) \ 56 OVERLOADED_OPERATOR(Name,Spelling,unknown,Unary,Binary,MemberOnly) 57 #endif 58 59 OVERLOADED_OPERATOR_MULTI(New , "new" , true , true , false) 60 OVERLOADED_OPERATOR_MULTI(Delete , "delete" , true , true , false) 61 OVERLOADED_OPERATOR_MULTI(Array_New , "new[]" , true , true , false) 62 OVERLOADED_OPERATOR_MULTI(Array_Delete , "delete[]" , true , true , false) 63 OVERLOADED_OPERATOR(Plus , "+" , plus , true , true , false) 64 OVERLOADED_OPERATOR(Minus , "-" , minus , true , true , false) 65 OVERLOADED_OPERATOR(Star , "*" , star , true , true , false) 66 OVERLOADED_OPERATOR(Slash , "/" , slash , false, true , false) 67 OVERLOADED_OPERATOR(Percent , "%" , percent , false, true , false) 68 OVERLOADED_OPERATOR(Caret , "^" , caret , false, true , false) 69 OVERLOADED_OPERATOR(Amp , "&" , amp , true , true , false) 70 OVERLOADED_OPERATOR(Pipe , "|" , pipe , false, true , false) 71 OVERLOADED_OPERATOR(Tilde , "~" , tilde , true , false, false) 72 OVERLOADED_OPERATOR(Exclaim , "!" , exclaim , true , false, false) 73 OVERLOADED_OPERATOR(Equal , "=" , equal , false, true , true) 74 OVERLOADED_OPERATOR(Less , "<" , less , false, true , false) 75 OVERLOADED_OPERATOR(Greater , ">" , greater , false, true , false) 76 OVERLOADED_OPERATOR(PlusEqual , "+=" , plusequal , false, true , false) 77 OVERLOADED_OPERATOR(MinusEqual , "-=" , minusequal , false, true , false) 78 OVERLOADED_OPERATOR(StarEqual , "*=" , starequal , false, true , false) 79 OVERLOADED_OPERATOR(SlashEqual , "/=" , slashequal , false, true , false) 80 OVERLOADED_OPERATOR(PercentEqual , "%=" , percentequal , false, true , false) 81 OVERLOADED_OPERATOR(CaretEqual , "^=" , caretequal , false, true , false) 82 OVERLOADED_OPERATOR(AmpEqual , "&=" , ampequal , false, true , false) 83 OVERLOADED_OPERATOR(PipeEqual , "|=" , pipeequal , false, true , false) 84 OVERLOADED_OPERATOR(LessLess , "<<" , lessless , false, true , false) 85 OVERLOADED_OPERATOR(GreaterGreater , ">>" , greatergreater , false, true , false) 86 OVERLOADED_OPERATOR(LessLessEqual , "<<=" , lesslessequal , false, true , false) 87 OVERLOADED_OPERATOR(GreaterGreaterEqual , ">>=" , greatergreaterequal, false, true , false) 88 OVERLOADED_OPERATOR(EqualEqual , "==" , equalequal , false, true , false) 89 OVERLOADED_OPERATOR(ExclaimEqual , "!=" , exclaimequal , false, true , false) 90 OVERLOADED_OPERATOR(LessEqual , "<=" , lessequal , false, true , false) 91 OVERLOADED_OPERATOR(GreaterEqual , ">=" , greaterequal , false, true , false) 92 OVERLOADED_OPERATOR(AmpAmp , "&&" , ampamp , false, true , false) 93 OVERLOADED_OPERATOR(PipePipe , "||" , pipepipe , false, true , false) 94 OVERLOADED_OPERATOR(PlusPlus , "++" , plusplus , true , true , false) 95 OVERLOADED_OPERATOR(MinusMinus , "--" , minusminus , true , true , false) 96 OVERLOADED_OPERATOR(Comma , "," , comma , false, true , false) 97 OVERLOADED_OPERATOR(ArrowStar , "->*" , arrowstar , false, true , false) 98 OVERLOADED_OPERATOR(Arrow , "->" , arrow , true , false, true) 99 OVERLOADED_OPERATOR_MULTI(Call , "()" , true , true , true) 100 OVERLOADED_OPERATOR_MULTI(Subscript , "[]" , false, true , true) 101 // ?: can *not* be overloaded, but we need the overload 102 // resolution machinery for it. 103 OVERLOADED_OPERATOR_MULTI(Conditional , "?" , false, true , false) 104 OVERLOADED_OPERATOR(Coawait , "co_await", kw_co_await , true , false, false) 105 106 #undef OVERLOADED_OPERATOR_MULTI 107 #undef OVERLOADED_OPERATOR 108
