Only a single instance of a specific MediaTypeEnum can be created, so we can check using ==.

 public static MediaTypeEnum fromCode(int key) 
{
        // @todo optimization needed
        for (int i = 0; i <  ALL.size(); i++)
        {
            if (key == ((MediaTypeEnum) ALL.get(i)).getCode())
            {
                return (MediaTypeEnum) ALL.get(i);
            }
        }
        // lookup failed
        return null;
}

lookup a media type by key.

 public static MediaTypeEnum fromCode(Integer key) 
{
        if (key == null)
        {
            return null;
        }
        return fromCode(key.intValue());
}

lookup a media type by an Integer key.

 public static MediaTypeEnum fromIntegerCode(Integer key) 
{
        return fromCode(key);
}

lookup a media type by an Integer key.

 public static MediaTypeEnum fromName(String code) 
{
        // @todo optimization needed
        for (int i = 0; i <  ALL.size(); i++)
        {
            if (((MediaTypeEnum) ALL.get(i)).getName().equals(code))
            {
                return ((MediaTypeEnum) ALL.get(i));
            }
        }
        // lookup failed
        return null;
}

Lookup a media type by a String key.

 public int getCode() 
{
        return this.enumCode;
}

returns the int code.

 public String getName() 
{
        return this.enumName;
}

returns the description.

 public static int getSize() 
{
        return ALL.size();
}

Returns the number of media type currently loaded.

 public int hashCode() 
{
        return new HashCodeBuilder(1188997057, -1289297553).append(this.enumCode).toHashCode();
}

 public static Iterator iterator() 
{
        return ALL.iterator();
}

returns an iterator on all the media type.

 public static synchronized MediaTypeEnum registerMediaType(String name) 
{
        MediaTypeEnum existing = fromName(name);
        if (existing == null)
        {
            existing = new MediaTypeEnum(ALL.size() + 1, name);
        }
        return existing;
}

Register a new MediaType. If name is already assigned the existing instance is returned, otherwise a new instance is created.

 public String toString() 
{
        return getName();
}

returns the media type description.
