public InputStream getInputStream() throws IOException, ProcessingException(Code)
Get the input stream for this source.



getLastModified
public long getLastModified()(Code)



getOutputStream
public OutputStream getOutputStream() throws IOException, ProcessingException(Code)
Get an output stream to write to this source. The output stream returned actually writes to a temp file that replaces the real one on close. This temp file is used as lock to forbid multiple simultaneous writes. The real file is updated atomically when the output stream is closed.
