OverloadedUnaryMinus¶
Unary minus overloaded for a user-defined type.
Declaration¶
Syntax¶
OverloadedUnaryMinus(expr arg, ttype type, expr? value,
expr overloaded)
Arguments¶
Argument |
Description |
|---|---|
|
the operand, as written. |
|
the type of the expression. |
|
the compile time value of the expression, when the frontend could fold it; |
|
the FunctionCall that implements the operator for this type. |
Return values¶
The value of the expression.
Description¶
-a where a is of a derived type, with the call that implements it in
overloaded.
