Title: C# Struct implementing interfaces
Post by: kossmann on March 09, 2004, 01:05:46 pm

I forward engineer from EA structs (struct stereotype as opposed to a class). My structs have attributes, and also implement one or more interfaces.

When I reverse engineer a struct such as

internal struct MyStruct : ICompare
{
     internal int i1;
     internal int i2;

     int CompareTo(object obj){
           return i1 - ((MyStruct)obj).i1;
     }
}

it works fine, but then when I forward engineer that again, the Interface being implemented disappears, ie. the forward engineering produces:

internal struct MyStruct
{
     internal int i1;
     internal int i2;

     int CompareTo(object obj){
           return i1 - ((MyStruct)obj).i1;
     }
}


Any ideas?

Hi Rainer,

Thanks for the note.

This is caused by an error in one of the the C# code generation templates.

We will fix this for release of EA 4.0.

As a short term work around, you can override the default C# "ClassInherits" code template for the struct stereotype:

1. Open the Code Template Editor (Ctrl+Shift+P)
2. Select C# as the language
3. Select the ClassInherits template
4. Select the struct stereotype override
5. Replace the line :

$interfaces=%list="ClassInterfaces" @separator=", "%

with

$interfaces=%list="ClassInterface" @separator=", "%
6. Click save

Next time you generate the interface should appear.

I hope this helps.

Regards,
Ben

Thanks, Ben. That did the trick.
