Description Antao Almada 2015-07-17 06:14:15 UTC
I have a class that implements a Java interface defined in a .jar and converted to C# using a binding project. The compilation is successful until I do the following changes:

- The interface has a method with a parameter of type 'long' and the class contains some constants to be used. I want to change this into an enum. 

- I create the enum in EnumFields.xml:

<mapping clr-enum-type="MyEnum" jni-class="com/company/myClass">
 <field clr-name="First" jni-name="FIRST_VALUE" value="0" />
 <field clr-name="Second" jni-name="SECOND_VALUE" value="1" />

- I change the parameter type of the interface method in EnumMethods.xml:

<mapping jni-interface="com/company/iInterface">
 <method jni-name="methodName" parameter="type" clr-enum-type="MyEnum"  />

- I now get the following error:

Error: MyCSharpClass is not abstract and does not override abstract method methodName(long) in iInterface

- Double-clicking on the error shows that Java version of my C# class (in the obj folder) contains the method but its parameter type is int:

public MyCSharpClass 
 extends java.lang.Object
 public void methodName(int p0)
This is related to bug #27307 I reported before.

Unfortunately it is not possible for non-integer parameters and return values. You need to write non-enum-specific metadata xml changes.
