RemotePath

public RemotePath(java.lang.String url,
                  Path dbDirectory,
                  java.lang.String tableName)
           throws java.lang.Exception

Create the root new RemoteFilesystem

Parameters:

url - the remote url

Throws:

java.lang.Exception

RemotePath

protected RemotePath(RemotePathRoot root,
                     java.lang.String userPath,
