> If a COSBase is directly embedded in a COSObject, it should not be assigned a new object
number by the writer. We suggest the following implementation for `COSWriter.getObjectKey(COSBase)`:

> {code:java}
> /**
>  * This will get the object key for the object.
>  *
>  * @param obj The object to get the key for.
>  *
>  * @return The object key for the object.
> */
> protected COSObjectKey getObjectKey( COSBase obj )
> {
>     COSBase actual = obj;
>     if( actual instanceof COSObject )
>     {
>         actual = ((COSObject)obj).getObject();
>     }
>     COSObjectKey key = null;
>     key = objectKeys.get(obj);
>     if( key == null && actual != null )
>     {
>         key = objectKeys.get(actual);
>     } 
>     if (key == null)
>     {
>         setNumber(getNumber()+1);
>         key = new COSObjectKey(getNumber(),0);
>         objectKeys.put(obj, key);
>         if( actual != null )
>         {
>             objectKeys.put(actual, key);
>         }
>     }
>     return key;
> }
> {code}
