You can use closures to achieve a similar effect, basically the same way you would do information hiding with Javascript.

package test

class FunctionTests {

    def privilagedObj = {

        def privVar = 'foo'

        def privateFunc = { x -> println "${privVar} ${x}"}

        return {x -> privateFunc(x) } 
    }

    public static void main(String[] args) {

        def test = new FunctionTests().privilagedObj()

        test('bar')

    }
}
