Constructor annotation

[Eva Krejcirova]

Hi All,

when we retired builders, we caused a problem for FXML which doesn't 
have a way to create classes without default constructors. Back then we 
decided to use an annotation for this but never actually got to 
implement it and we need to fix this for FX8. I am in the process of 
adding this functionality to FXMLLoader but we need to decide how the 
annotation will look like and I could use some help with this.

We cannot use already existing ConstructorProperties for this, because 
it's java.beans package and we don't want to create to dependency on 
this package in JavaFX, so we need to introduce a new annotation.

We have two options:

1. Annotate the whole constructor:
e.g.
     @ConstructorArguments({"a", "b", "list"})
     public ImmutableClass(int a, int b, Integer... list)

2. Annotate the arguments:
e.g.
     public ImmutableClass(@FXMLArgument("a") int a, 
@FXMLArgument("b")int b, @FXMLArgument("list")Integer... list)


Which option do you like more and how should the annotation be named?

Thanks,
Eva
