Method Summary
void	close()           This method closes the stream.
void	flush()           This method forces any data that may have been buffered to be written to the underlying output device.
void	write(byte[] b)           This method all the writes bytes from the passed array to the output stream.
void	write(byte[] b, int off, int len)           This method writes len bytes from the specified array b starting at index off into the array.

Method Detail

close

public void close()

Description copied from class: java.io.OutputStream

This method closes the stream. Any internal or native resources associated with this stream are freed. Any subsequent attempt to access the stream might throw an exception.

This method in this class does nothing.

---

flush

public void flush()

Description copied from class: java.io.OutputStream

This method forces any data that may have been buffered to be written to the underlying output device. Please note that the host environment might perform its own buffering unbeknowst to Java. In that case, a write made (for example, to a disk drive) might be cached in OS buffers instead of actually being written to disk.

This method in this class does nothing.

---

write

public void write(byte[] b)
           throws java.io.IOException

Description copied from class: java.io.OutputStream

This method all the writes bytes from the passed array to the output stream. This method is equivalent to write(b, 0, buf.length) which is exactly how it is implemented in this class.

---

write

public void write(byte[] b,
                  int off,
                  int len)
           throws java.io.IOException

Description copied from class: java.io.OutputStream

This method writes len bytes from the specified array b starting at index off into the array.

This method in this class calls the single byte write() method in a loop until all bytes have been written. Subclasses should override this method if possible in order to provide a more efficent implementation.

---

write

public void write(int b)
           throws java.io.IOException

Description copied from class: java.io.OutputStream

This method writes a single byte to the output stream. The byte written is the low eight bits of the int passed and a argument.

Subclasses must provide an implementation of this abstract method
