Consider the following code:
class classComputer {
private string pstrName;
final @property string name() { return this.pstrName; }
final @property void name(in string lstrName) { this.pstrName = lstrName; }
this(
string lstrComputerName
) {
this.pstrName = lstrComputerName;
}
}
class classComputers {
classComputers lhs;
classComputers rhs;
int opApply(int delegate(classComputers) dg) { /// boilerplate code to handle the class's default collection
if (lhs && lhs.opApply(dg)) return 1;
if (dg(this)) return 1;
if (rhs && rhs.opApply(dg)) return 1;
return 0;
}
public classComputer[] computers; /// how can I tag this as the default property ?
}
void main (
) {
classComputers lobjComputers = new classComputers;
lobjComputers.computers ~= new classComputer("dell");
lobjComputers.computers ~= new classComputer("ibm");
lobjComputers.computers ~= new classComputer("apple");
lobjComputers.computers[1].name = r"lenovo";
foreach(lobjComputer; lobjComputers.computers) { writeln(lobjComputer.name); }
///foreach(lobjComputer; lobjComputers) { writeln(lobjComputer.name); } /// with default property (if possible)
}
The above code works correctly, however, avoiding the redundancy of lobjComputers.computers will be a plus.
Also tell me if the collection is implemented the right way, it is my first code using the opApply() delegate which I don't deeply understand for the time being.
