[jira] [Commented] (NET-310) FTPCommand conversion to use enum

["Sebb (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NET-310?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13560862#comment-13560862 ] 

Sebb commented on NET-310:
--------------------------

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

{noformat}
    ABOR(FTPCommand.ABOR),
...
    USER(FTPCommand.USER),

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

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?
