Subject [jira] [Commented] (NET-310) FTPCommand conversion to use enum
Date Wed, 23 Jan 2013 17:45:18 GMT


Sebb commented on NET-310:

Note: it would be possible to record the original constants with the enum, for example:


    private final int originalCode;
    FTPCommandEnum(int original) {
    int getOriginalCode() {
        return originalCode;

However, there does not seem to be any need for this.

> Seems to me it would be sensible to replace the integer values in the FTPCommand class
with an enum.
> I propose creating a new enum class (called FTPCommands) which contains the enum and
aliases. The existing FTPCommand class is then rewritten using the enum ordinals; and the
FTP class is changed to use the enums internally. Existing public methods which use an integer
for the command id are deprecated.
> If there are any further commands added to the set lter, they should only be added to
the enum, and no corresponding ints should be defined.
> See attached patch (to follow). I've not fixed the FTP subclasses yet as I wanted to
get agreement on the approach first.
> Note that the new class name FTPCommands is very similar to the old class FTPCommand;
of course that can be changed.
> Comments? Suggestions?
