      • convertStreamTo

        public java.io.ByteArrayOutputStream convertStreamTo​(java.io.InputStream is)
                                              throws java.io.IOException
        Convert the InputStream to String we use the Reader.read(char[] buffer) method. We iterate until the Reader return -1 which means there's no more data to read.
        Parameters:
        is - the input stream
        Returns:
        the result
        Throws:
        java.io.IOException - in case of error

                                    throws java.io.IOException
        Convert the InputStream to String we use the Reader.read(char[] buffer) method. We iterate until the Reader return -1 which means there's no more data to read.
        Parameters:
        is - the input stream
        Returns:
        the result
        Throws:
        java.io.IOException - in case of error

      • convertStreamToStr

        public java.lang.String convertStreamToStr​(java.io.InputStream is,
                                           java.lang.String charsetName)
                                    throws java.io.IOException
        Convert the InputStream to String we use the Reader.read(char[] buffer) method. We iterate until the Reader return -1 which means there's no more data to read.
        Parameters:
        is - the input stream
        charsetName - the charset name
        Returns:
        the result
        Throws:
        java.io.IOException - in case of error

      • convertStreamToNewInputStream

        public java.io.InputStream convertStreamToNewInputStream​(java.io.InputStream is)
                                                  throws java.io.IOException
        Convert the InputStream to String we use the Reader.read(char[] buffer) method. We iterate until the Reader return -1 which means there's no more data to read.
        Parameters:
        is - the input stream
        Returns:
        the result
        Throws:
        java.io.IOException - in case of error

      • channelCopy

        public long channelCopy​(java.io.InputStream src,
                        java.io.OutputStream dest)
                 throws java.io.IOException
        This method copies data from the src and writes it to the dest until EOF on src.
        Parameters:
        src - the source stream
        dest - the destination stream
        Returns:
        the copied bytes
        Throws:
        java.io.IOException - in case of error

      • channelCopy

        public long channelCopy​(java.nio.channels.ReadableByteChannel src,
                        java.nio.channels.WritableByteChannel dest)
                 throws java.io.IOException
        This method copies data from the src channel and writes it to the dest channel until EOF on src. This implementation makes use of compact() on the temp buffer to pack down the data if the buffer wasn't fully drained. This may result in data copying, but minimizes system calls. It also requires a cleanup loop to make sure all the data gets sent.
        Parameters:
        src - the source channel
        dest - the destination channel
        Returns:
        the copied bytes
        Throws:
        java.io.IOException - in case of error

      • close

        public void close​(java.io.Closeable closeable)
        Close silent a stream
        Parameters:
        closeable - close
