  • Method Details

    • write

      public void write(byte[] cbuf, int off, int len) throws IOException
      Write a portion of an array of characters.
      Overrides:
      write in class OutputStream
      Parameters:
      cbuf - Array of characters
      off - Offset from which to start writing characters
      len - Number of characters to write
      Throws:
      IOException - If an I/O error occurs

    • write

      public void write(byte[] b) throws IOException
      Writes b.length bytes from the specified byte array to this output stream. The general contract for write(b) is that it should have exactly the same effect as the call write(b, 0, b.length).
      Overrides:
      write in class OutputStream
      Parameters:
      b - the data.
      Throws:
      IOException - if an I/O error occurs.

    • write

      public void write(int b) throws IOException
      Writes the specified byte to this output stream. The general contract for write is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argument b. The 24 high-order bits of b are ignored.

      Subclasses of OutputStream must provide an implementation for this method.

      Specified by:
      write in class OutputStream
      Parameters:
      b - the byte.
      Throws:
      IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

    • flush

      public void flush() throws 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 Flushable
      Overrides:
      flush in class OutputStream
      Throws:
      IOException - If an I/O error occurs

    • close

      public void close() throws 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 AutoCloseable
      Specified by:
      close in interface Closeable
      Overrides:
      close in class OutputStream
      Throws:
      IOException - If an I/O error occurs
