When overriding a property setter in a descendant class, the getter must also
be overridden (or explicitly called with super), otherwise the compiler doesnt
understand we want to call the getter.
example:
---
import std.stdio;
class foo
{
private int fMyField;
public:
@property
{
void MyField(int aValue){fMyField = aValue;}
int MyField(){return fMyField;}
}
}
class bar: foo
{
public:
@property
{
override void MyField(int aValue){fMyField = 0;}
}
this()
{
writeln(MyField());// dmd should detect that the getter exists in foo.
writeln(super.MyField());//super. would be superfluous
}
}
void main(string[] args)
{
auto Bar = new bar;
}
---
result: compile-time error,
"Error: function f337.bar.MyField (int aValue) is not callable using argument
types ()"
