How will the object know that Stapler has completed calling DataBoundSetters
(that all configuration data has been applied)?

great,
so next step is to be able to directly annotate fields à la hibernate :)
class Foo {
@DataBound
int a,b,c,d;
}

Today, many complex plugins suffer from a massive constructor annotated with
@DataBoundConstructor.
This is because the form data-binding requires that all the parameters passed
in through the constructor. See xcode plugin [1] for an example of this. The
situation was worse with plugins that are used by other plugins, which needed
to preserve ever-increasing list of constructors to remain backward compatible.
Starting Jenkins 1.535, this problem is no more. Stapler can not only look for
@DataBoundConstructor, but it'll also perform setter injection on methods
annotated with @DataBoundSetter.
So whereas you had to write:
class Foo {
int a,b,c,d;
@DataBoundConstructor
public Foo(int a, int b, int c, int d) {
this.a = a;
this.b = b;
this.c = c;
this.d = d;
}
}
You can now write:
class Foo {
int a,b,c,d;
@DataBoundConstructor
public Foo(int a, int b) {
this.a = a;
this.b = b;
}
@DataBoundSetter
public void setC(int c) { this.c = c; }
@DataBoundSetter
public void setD(int d) { this.d = d; }
}
Or even:
class Foo {
int a,b,c,d;
@DataBoundConstructor
public Foo() {}
@DataBoundSetter
public void setA(int a) { this.a = a; }
@DataBoundSetter
public void setC(int b) { this.b = b; }
@DataBoundSetter
public void setC(int c) { this.c = c; }
@DataBoundSetter
public void setD(int d) { this.d = d; }
}
This will make it easier to evolve plugins that have a large number of
configuration options.
