    • getBuffer

      public java.lang.StringBuffer getBuffer()
    • write

      public void write(int c) throws java.io.IOException
      Write a single character. The character to be written is contained in the 16 low-order bits of the given integer value; the 16 high-order bits are ignored.

      Subclasses that intend to support efficient single-character output should override this method.

      Overrides:
      write in class java.io.Writer
      Parameters:
      c - int specifying a character to be written.
      Throws:
      java.io.IOException - If an I/O error occurs
    • write

      public void write(java.lang.String str) throws java.io.IOException
      Write a string.
      Overrides:
      write in class java.io.Writer
      Parameters:
      str - String to be written
      Throws:
      java.io.IOException - If an I/O error occurs
    • write

      public void write(char[] cbuf, int off, int len) throws java.io.IOException
      Write a portion of an array of characters.
      Specified by:
      write in class java.io.Writer
      Parameters:
      cbuf - Array of characters
      off - Offset from which to start writing characters
      len - Number of characters to write
      Throws:
      java.io.IOException - If an I/O error occurs
    • flush

      public void flush() throws java.io.IOException
      Flush 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.

      If the intended destination of this stream is an abstraction provided by the underlying operating system, for example a file, then flushing the stream guarantees only that bytes previously written to the stream are passed to the operating system for writing; it does not guarantee that they are actually written to a physical device such as a disk drive.

      Specified by:
      flush in interface java.io.Flushable
      Specified by:
      flush in class java.io.Writer
      Throws:
      java.io.IOException - If an I/O error occurs
    • close

      public void close() throws java.io.IOException
      Close the stream, flushing it first. Once a stream has been closed, further write() or flush() invocations will cause an IOException to be thrown. Closing a previously-closed stream, however, has no effect.
      Specified by:
      close in interface java.lang.AutoCloseable
      Specified by:
      close in interface java.io.Closeable
      Specified by:
      close in class java.io.Writer
      Throws:
      java.io.IOException - If an I/O error occurs
