The following code using @MapConstructor on a static inner class raises
a compile time error (see end of mail; different error when making the
inner class non-static):
import groovy.transform.CompileStatic
import groovy.transform.MapConstructor
@CompileStatic
class GroovyMapConstructorCheck {
@MapConstructor(noArg = true)
static class Goo {
final String s0 = "text0"
final int x0
final String s1
final String s2 = "TEXT2"
final o0
@Override
public String toString() {
return "Goo(|$s0|,|$x0|,|$s1|,|$s2|,|$o0|)"
}
}
void go() {
println new Goo()
println new Goo(s0:"abc")
println new Goo(x0:123, s0:"abc")
println new Goo(s1:"S1", s2:"S2", x0:-999, o0:new Object(),
s0:"S0")
final goo = new Goo(s1:"S1", s2:"S2", x0:-999, o0:new Object(),
s0:"S0")
}
}
final check = new GroovyMapConstructorCheck()
check.go()
