Generate D getters and setters automatically
accessors
module allows to generate getters and setters automatically.
Deprecation warning: accessors
has been succeeded by boilerplate.
import accessors;
class WithAccessors
{
@Read @Write
private int num_;
mixin(GenerateFieldAccessors);
}
@Read
and @Write
generate the following two methods:
public final @property auto num() inout @nogc nothrow pure @safe
{
return this.num_;
}
public final @property void num(int num) @nogc nothrow pure @safe
{
this.num_ = num;
}
The accessors names are derived from the appropriate member variables by
removing an underscore from the beginning or the end of the variable name.
As you can see there are multiple attributes that can be used to generate
getters and only one for the setters. The getters differ by the return
type. @Read
returns an inout
value, @ConstRead
- a const
value.
Visibility of the generated accessors is by default public
, but it can be
changed. In order to achieve this, you have to pass public
, protected
,private
or package
as argument to the attribute:
import accessors;
class WithAccessors
{
@Read("public") @Write("protected")
private int num_;
mixin(GenerateFieldAccessors);
}
import accessors;
import std.stdio;
class Person
{
@Read @Write
private uint age_;
@ConstRead
private string name_;
this(in string name, in uint age = 0)
{
this.name_ = name;
this.age_ = age;
}
mixin(GenerateFieldAccessors);
}
void main()
{
auto person = new Person("Saul Kripke");
person.age = 57;
writeln(person.name, ": ", person.age);
}
If you experience compile-time problems, open an
issue with the
information about the type of the member variable fails.
