      static long copyReader​(java.io.Reader source, java.io.Writer dest)
      Same as copyReader(source, dest, DEFAULT_COPY_BUFFER_SIZE);
      static long copyReader​(java.io.Reader source, java.io.Writer dest, int bufferSize)
      Copies the contents of a Reader to a Writer using a copy buffer of a given size.
      static long copyReader​(java.io.Reader source, java.io.Writer dest, int bufferSize, long streamSize, CopyStreamListener listener)
      Copies the contents of a Reader to a Writer using a copy buffer of a given size and notifies the provided CopyStreamListener of the progress of the copy operation by calling its bytesTransferred(long, int) method after each write to the destination.

        public static final long copyStream​(java.io.InputStream source,
                                            java.io.OutputStream dest,
                                            int bufferSize,
                                            long streamSize,
                                            CopyStreamListener listener)
                                     throws CopyStreamException
        Copies the contents of an InputStream to an OutputStream using a copy buffer of a given size and notifies the provided CopyStreamListener of the progress of the copy operation by calling its bytesTransferred(long, int) method after each write to the destination. If you wish to notify more than one listener you should use a CopyStreamAdapter as the listener and register the additional listeners with the CopyStreamAdapter.

        The contents of the InputStream are read until the end of the stream is reached, but neither the source nor the destination are closed. You must do this yourself outside of the method call. The number of bytes read/written is returned.

        Parameters:
        source - The source InputStream.
        dest - The destination OutputStream.
        bufferSize - The number of bytes to buffer during the copy.
        streamSize - The number of bytes in the stream being copied. Should be set to CopyStreamEvent.UNKNOWN_STREAM_SIZE if unknown.
        listener - The CopyStreamListener to notify of progress. If this parameter is null, notification is not attempted.
        Throws:
        CopyStreamException - If an error occurs while reading from the source or writing to the destination. The CopyStreamException will contain the number of bytes confirmed to have been transferred before an IOException occurred, and it will also contain the IOException that caused the error. These values can be retrieved with the CopyStreamException getTotalBytesTransferred() and getIOException() methods.

        bufferSize - The number of characters to buffer during the copy.
        streamSize - The number of characters in the stream being copied. Should be set to CopyStreamEvent.UNKNOWN_STREAM_SIZE if unknown.

        Returns:
        The number of characters read/written in the copy operation.
