Eric Milles updated GROOVY-11853:
---------------------------------
Description:
There were some scenarios that allowed access to an object's outer class
members that no longer work under the GROOVY-11823 redesign.
1) access to outer class field through object expression:
{code:groovy}
class Outer {
class Inner {
}
def p = "p"
}
def o = new Outer()
def i = new Outer.Inner(o)
println i.p
{code}
2) outer class method overloads
{code:groovy}
interface A {
def run()
}
class B {
def test() {
def runner = new A() {
def run() { return x } // which "x" is this?
}
runner.run()
}
private x = 1
void setX(val) { x = val }
}
class C extends B {
def x = 'string' // hides 'B.@x' and overrides 'B.setX(val)'
}
print new C().test()
{code}
3) outer class {{invokeMethod}} or other such MOP overloads:
{code:groovy}
String string = new Object() {
@Override
String toString() {
// outer class is a Script and overrides getProperty, setProperty and
invokeMethod
dynamicVariable = "foo"
}
}
println dynamicVariable
{code}
