Steve Loughran commented on HADOOP-13591:
-----------------------------------------
I'm =0 on making "/" a constant, as I don't see anyone ever changing it. What
probably makes more sense is to factor out the repeated operation. From S3aFS
{code}
/**
* Turns a path (relative or otherwise) into an S3 key, adding a trailing
* "/" if the path is not the root <i>and</i> does not already have a "/"
* at the end.
*
* @param key s3 key or ""
* @return the with a trailing "/", or, if it is the root key, "",
*/
private String maybeAddTrailingSlash(String key) {
if (!key.isEmpty() && !key.endsWith("/")) {
return key + '/';
} else {
return key;
}
}
{code}
+can you stop your IDE automatically converting imports to .* ? It complicates
merging and may create conflicts now that there's a {{java.io.FileSystem}} in
Java7+.
