Yes, you can get rid of the no-arg constructor and control visibility for
map and tuple constructors
but can't currently control visibility for the no-arg constructor. We'd
need an annotation attribute
something like what you suggested. It's a little strange in that the
visibilityId would control visibility
for both the map and no-arg variations unless the noArgVisibilityId
attribute was set. Also, if you
set noArg=false for @MapConstructor and defaults=true
for @TupleConstructor, you get the
no-arg constructor from the tuple constructor defaults with no way to set
the visibility independently
for the 2 or more related constructors.
import groovy.transform.*
import static groovy.transform.options.Visibility.PRIVATE
@Immutable
@MapConstructor(noArg=false)
@TupleConstructor(defaults=true, visibilityId='hidden')
@VisibilityOptions(id = 'hidden', value = PRIVATE)
class Foo {
String a, b, c
}
assert Foo.declaredConstructors*.modifiers == [2, 2, 2, 2, 1]
