Re: Strategy or A factory with Template Method

Responding to Thinkmind...

Hi Group

I was going through some blogs on the net. Here is one I am looking at.

What's wrong with the following code?

void uploadFiles(Set<File> files, boolean sftp, boolean scp, ...) {
    if (sftp) {
        // upload via SFTP
    } else if (scp) {
        // upload via SCP
    } else {
        // upload via FTP
    }
}

What the author of the blog says to use Strategy Design Pattern to
implement this.

But my question is cannot we use a Factory Design Pattern with a
Template Method. Which one is more appropriate. Can any one give me
idea on this.

Implementing the Strategy pattern will be simpler. B-) All one is doing is selecting a particular behavior to execute based upon context. That sort of selection is exactly what Strategy does so implementing with Strategy would be simple and intuitive.

Perhaps a more basic response is to turn the question around: Why would one want to use a factory pattern here at all? There are no instances being created.

There is nothing wrong with me that could
not be cured by a capful of Drano.
