Using enums with Pococapsule (C++ IoC-container)

Question

Is there a way of supplying enum values as method-args in pococapsule without resorting to factory-methods?

Let say I have a class that take an enum value in its constructor

class A
{
    A(myEnum val);
}

Using Pococapsule xml configuration: I would like to express something like this:

<bean id="A" class="A">
    <method-arg type="MyEnum" value="MyEnum::Value1" />
</bean>

However, since pococapsule's basic types only includes built in types such as short, char, etc this is not possible.
How would I go about to instantiate a class A using pococapsule?

I could resort to using factory methods something like this:

MyEnum GetMyEnumValue1()
{
    return MyEnum::Value1;
}

<bean id="A" class="A">
    <method-arg factory-method="GetMyEnumValue1" />
</bean>

Which isn't very practical. I would have to implement a new factory method for every possible value of each and every enum used.

Some would argue that enum:s shouldn't be passed in constructors or setter methods as it is a sign of a class doing to much. Yes I agree. However, there is a lot of third party code and c++ frameworks out there that uses this style, so I need to be able to do this.

Edit: The issue was resolved on Pococapsule's discussion forum. The work-around in this specific case was to have factory methods perform the desired action. It is not as flexible as declaring enum-use in the xml-config file, but it moved the project forward. Thanks Ke for your help.

Answer 1

In C/C++ enums are able to be passed as int implicitly, therefore, you can simply do:

You can also use the DSM feature to define your own extend schema that supports your specific enum (it should be similar to the user example in examples/basic-ioc/ext-schema where DSM is used to typesafely support user defined Map type).

Answer 2

(repost, as the XML code was filtered out in previous reply)

In C/C++ enums are able to be passed as int implicitly, therefore, you can simply have type="long" in the method-arg element.

You can also use the DSM feature to define your own extend schema that supports your specific enum (it should be similar to the user example in examples/basic-ioc/ext-schema where DSM is used to typesafely support user defined Map type).
