  • Method Details

    • openOnce

      InputStream openOnce() throws IOException
      Open the stream once.

      Beware that this interface is only intended for lazy opening a stream, i.e. to delay this opening (or not open the stream at all). It is not intended to open the stream several times. Some implementations may fail if an attempt to open a stream several times is made. This is particularly true for network-based streams.

      Returns:
      opened stream
      Throws:
      IOException - if stream cannot be opened
