NumberFormatException specifying hex [message #417717]

Hi All

I am Wondering if anyone knows how to specify a hex value for an enum.
I am using eclipse 3.3

When I use the emf editor, I see a NumberFormatException when entering the
value. Is there some special syntax or is this perpahs already fixed in
3.3.1.1 ?

I also tried to import some annotated code like the following...

public enum MYENUM implements Enumerator {

/**
* @model
*/
public static final int MYENUM_GOOD = 0x00000000;

/**
* @model
*/
public static final int MYENUM_BAD = 0xDEADBEEF;

}

this would work when i used classes, as in ....

public class MYENUM extends AbstractEnumerator {

/**
* @model
*/
public static final int MYENUM_GOOD = 0x00000000;

/**
* @model
*/
public static final int MYENUM_BAD = 0xDEADBEEF;

}

Andy,

You could open a bug so that we accept things other than decimal
literals in annotated Java, but in general, when we generate code, we'll
still generate a decimal integer value. You could include a
documentation annotation to describe the value in a way that will show
up in the generated Javadoc as a hexadecimal value..

Ed,
Thanks very much for your prompt reply.

The reason I wanted to do this, is because I am parsing many c header
files to generate the annotated java files (with the @model tags), and
some of them have hex values for #define.

The number of files I have is significant to not want to convert
(appreciate I could do this in my c app), so this was useful to me when
implementing AbstractEnumerator for my class type enums previously.

I will therefore open a Bug report.

Thanks again and many regards,
Andy
