16 /// In this file, each of the overloadable C++ operators is enumerated
17 /// with either the OVERLOADED_OPERATOR or OVERLOADED_OPERATOR_MULTI
18 /// macro, each of which can be specified by the code including this
19 /// file. OVERLOADED_OPERATOR is used for single-token operators
20 /// (e.g., "+"), and has six arguments:
22 /// Name: The name of the token. OO_Name will be the name of the
23 /// corresponding enumerator in OverloadedOperatorKind in
26 /// Spelling: A string that provides a canonical spelling for the
27 /// operator, e.g., "operator+".
29 /// Token: The name of the token that specifies the operator, e.g.,
30 /// "plus" for operator+ or "greatergreaterequal" for
31 /// "operator>>=". With a "kw_" prefix, the token name can be used as
32 /// an enumerator into the TokenKind enumeration.
34 /// Unary: True if the operator can be declared as a unary operator.
36 /// Binary: True if the operator can be declared as a binary
37 /// operator. Note that some operators (e.g., "operator+" and
38 /// "operator*") can be both unary and binary.
40 /// MemberOnly: True if this operator can only be declared as a
41 /// non-static member function. False if the operator can be both a
42 /// non-member function and a non-static member function.
44 /// OVERLOADED_OPERATOR_MULTI is used to enumerate the multi-token
45 /// overloaded operator names, e.g., "operator delete []". The macro
46 /// has all of the parameters of OVERLOADED_OPERATOR except Token,
