Method Details

ensureInputStreamIsValid

private void ensureInputStreamIsValid()
                               throws IOException

This internal method ensures that the zip file is open and that the underlying input stream is valid. Upon successful completion, the underlying input stream will be valid and the local mutex will be held.

Throws:

IOException - if the was an error handling the input stream.
