Hi,<br />
<br />
Does anyone know how to detect if there is a setter for a property? The <br />
code below prints the same thing for both<br />
the setter and the getter of "front":<br />
<br />
==============================<br />
import std.traits;<br />
<br />
class Foo {<br />
uint num;<br />
<br />
@property ref uint front() {<br />
return num;<br />
}<br />
@property void front(uint i) {<br />
num = i;<br />
}<br />
<br />
ref uint front2() {<br />
return num;<br />
}<br />
}<br />
<br />
template isProperty(alias func) if (isCallable!(func)) {<br />
enum isProperty = (functionAttributes!(func) & <br />
FunctionAttribute.PROPERTY)==0 ? false : true;<br />
}<br />
<br />
template hasSetter(alias func) if (isCallable!(func)) {<br />
enum hasSetter = (isProperty!(func) && ParameterTypeTuple!(func).length > <br />
0 && ReturnType!(func).stringof != "void") ? true : false;<br />
}<br />
<br />
void main() {<br />
Foo foo;<br />
pragma(msg, hasSetter!(foo.front));<br />
<br />
static if (isProperty!(foo.front)) {<br />
pragma(msg, "property");<br />
} else {<br />
pragma(msg, "not a property");<br />
}<br />
<br />
alias MemberFunctionsTuple!(Foo,"front") fronts;<br />
foreach (s; fronts) {<br />
pragma(msg, ReturnType!(s)); // this line just prints "uint" for both <br />
"front" properties!<br />
}<br />
}<br />
============================<br />
<br />
<br />
Is this a compiler bug? Or am I wrong again?<br />
<br />
Thanks<br />
Rory<br />
