Groovy: Set dynamic nested method using string as path

Question

I have a path for an object within an object within an object and I want to set it using Groovy\'s dynamic abilities. Usually you can do so just by doing the following:

Answer 1

Following works correctly.

foo."bar"."setMe" = 'This is the string I set into Bar';

Without getProperty overriding you can achieve the same result using "${}" syntax for GString as the below code demonstrates

class Baz {
    String something
}

class Bar {

    Baz baz

}

class Foo {
    Bar bar
}

def foo = new Foo()
foo.bar = new Bar()
foo.bar.baz = new Baz()

def target = foo
def path = ["bar", "baz"]
for (value in path) {
    target = target."${value}"
}

target."something" = "someValue"
println foo.bar.baz.something

final println prints "someValue" as expected
