Class UTF8StreamWriter

    • Constructor Detail

      • UTF8StreamWriter

        public UTF8StreamWriter()
        Creates a UTF-8 writer having a byte buffer of moderate capacity (2048).

      • UTF8StreamWriter

        public UTF8StreamWriter​(int capacity)
        Creates a UTF-8 writer having a byte buffer of specified capacity.
        Parameters:
        capacity - the capacity of the byte buffer.

    • Method Detail

      • setOutput

        public UTF8StreamWriter setOutput​(OutputStream out)
        Sets the output stream to use for writing until this writer is closed. For example:[code] Writer writer = new UTF8StreamWriter().setOutputStream(out); [/code] is equivalent but writes faster than [code] Writer writer = new java.io.OutputStreamWriter(out, "UTF-8"); [/code]
        Parameters:
        out - the output stream.
        Returns:
        this UTF-8 writer.
        Throws:
        IllegalStateException - if this writer is being reused and it has not been closed or reset.

      • write

        public void write​(char c)
           throws IOException
        Writes a single character. This method supports 16-bits character surrogates.
        Parameters:
        c - char the character to be written (possibly a surrogate).
        Throws:
        IOException - if an I/O error occurs.

      • write

        public void write​(int code)
           throws IOException
        Writes a character given its 31-bits Unicode.
        Overrides:
        write in class Writer
        Parameters:
        code - the 31 bits Unicode of the character to be written.
        Throws:
        IOException - if an I/O error occurs.

      • write

        public void write​(char[] cbuf,
                  int off,
                  int len)
           throws IOException
        Writes a portion of an array of characters.
        Specified by:
        write in class Writer
        Parameters:
        cbuf - the array of characters.
        off - the offset from which to start writing characters.
        len - the number of characters to write.
        Throws:
        IOException - if an I/O error occurs.

      • write

        public void write​(String str,
                  int off,
                  int len)
           throws IOException
        Writes a portion of a string.
        Overrides:
        write in class Writer
        Parameters:
        str - a String.
        off - the offset from which to start writing characters.
        len - the number of characters to write.
        Throws:
        IOException - if an I/O error occurs

      • write

        public void write​(CharSequence csq)
           throws IOException
        Writes the specified character sequence.
        Parameters:
        csq - the character sequence.
        Throws:
        IOException - if an I/O error occurs

      • flush

        public void flush()
           throws IOException
        Flushes the stream. If the stream has saved any characters from the various write() methods in a buffer, write them immediately to their intended destination. Then, if that destination is another character or byte stream, flush it. Thus one flush() invocation will flush all the buffers in a chain of Writers and OutputStreams.
        Specified by:
        flush in interface Flushable
        Specified by:
        flush in class Writer
        Throws:
        IOException - if an I/O error occurs.

      • reset

        public void reset()
