How to check if CSFile exists

Hello there,

I have been looking for a method to check if a file/directory (CSFile) exists in TeamSite. Like, for regular filesystem we can use JDK exists() method for File object. I couldn't find such method in csssdk docs. I think, it's very natural to check a file exists of not. I was wondering what is the right way of doing it.

I wrote a custom method.

public boolean isCSFileExists(final String tsVPath) throws RuntimeException{
if(log.isDebugEnabled()) log.debug("checking if exists : " + tsVPath);
try {
        CSVPath csvPath = new CSVPath(tsVPath);
return csClient.getFile(csvPath) != null;
    }catch (CSException cse){
throw new RuntimeException(cse);
    }
}

But, it doesn't feel right that there is no method to check the existance of file in cssdk docs. May be I am not looking at the right place. Can anyone help me here?

Thanks

Rajesh

A more cleaner approach would be

public boolean csFileExists(final String tsVPath) throws RuntimeException{
if(log.isDebugEnabled()) log.debug("checking if exists : " + tsVPath);
try {
        CSVPath csvPath = new CSVPath(tsVPath);
        CSFile csFile = csClient.getFile(csvPath);
        if (csFile == null || (csFile instanceof CSHole))
        {
             return false;
        }
        return true;
    }
    }catch (CSException cse){
throw new RuntimeException(cse);
    }
}

I think, it more depends on the context. My intention here is to check the real existance of file or directory, means those were never created. Here existance is more like file was never created and never versioned.

CSHole is file type, it means the file was created, versioned and deleted. So instead of file existance, it's a kind of file type. So, I prefer to check the CSHole as file type as TeamSite expects than to take it as existance criteria which I have reflected in my existance criteria.

If you want to check the file existance and deletion of file in workarea then your method makes sense. But I think, keeping these two things separate makes your code loosley coupled as it gives you flexibility to check all the conditions separately than to checking the combination of two options.

I dont think there is a method like exists. If you already have the vpath and want to check if a file exists, then the null check on the csclient.getFile() is probably the only way to go. Or are you suggesting that you want to check for something in staging and you dont have the staging vpath.

Thanks!!

I guess, this is the only option I have. I am working on a batch process to upload an external data feed into TeamSite with nested directory structure.

So I wanted to check if cssdk api provides any easy way to check the existance of CSFile object to make things easy. But it seems, it needs all custom methods for such checks.
