    Description copied from interface: FileResource
    
    Opens a new input stream to read the contents of a resource and returns it. Note that implementations may be allocating native memory for the stream, so callers need to close this when they are done with it. users of this method should follow the pattern: close the stream where you open it.
    
    Specified by:
    
    inputStream in interface FileResource
    
    Returns:
    
    just opened InputStream
    
    Throws:
    
    ResourceException - is the file does not exists or if the resource is a directory
