Name
operator keyword — Function call syntax for operators
Synopsis
operator-function-id ::= operator op-symbol |
operator op-symbol < [template-arg-list] >
conversion-function-id ::= operator conversion-type-id
conversion-type-id ::= type-specifier-seq [conversion-declarator]
conversion-declarator ::= ptr-operator [conversion-declarator]
ptr-operator ::= * [cv-qualifier-seq] | & | [::] nested-name :: * [cv-qualifier-seq]The operator keyword converts
an operator symbol into function notation. You can use the operator keyword when invoking an operator
or when overloading an operator.
Example
int x =operator+(10, 32); complex<double> c, d; c.operator+=(d); operator+=(c, d); // Same as above bigintoperator*(const bigint& a, const bigint* b);
Table 12-1 lists the operator symbols (op-symbol) that can be overloaded. Alternative tokens (shown in parentheses) are interchangeable with their symbolic equivalents.
