             Summary: DelegatingScript should support different delegates for different operations
                 Key: GROOVY-7689
                 URL: https://issues.apache.org/jira/browse/GROOVY-7689
             Project: Groovy
          Issue Type: Improvement
    Affects Versions: 2.4.5
            Reporter: Jochen Kemnade


I'd like to use different "inputs" and "outputs" for a script.
For example if my input is {{[ x : 2 ]}} and my output is {{[ : ]}}, 
{code}
result = 2 * x
{code}
should lead to {{output == [ result : 4 ]}}. That means, getProperty should use the input and setProperty should use the output.
Currently, you can only set a single delegate for DelegatingScript, so that is not possible.
I suggest introducing the additional methods {{setDelegateForInvokeMethod, setDelegateForGetProperty, and setDelegateForSetProperty}} that set the delegates only for the respective methods. The existing {{setDelegate}} method would set all the delegates to the same object.
