Modifier and Type | Method and Description |

void |
close()
This method closes the stream.
|
protected void |
finalize()
This method (when overriden), will be called when the VM determines that the Object can be
garbage collected.
|
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[] data,
int offset,
int count)
This method writes
len bytes from the specified array
b starting at index off into the array. |
void |
write(int b)
This method writes a single byte to the output stream.

public void write(int b) throws IOException
int
passed as the argument.
Subclasses must provide an implementation of this method.
b
- The byte to be written to the output stream, passed as
the low eight bits of an int
IOException
- If an error occurspublic void write(byte[] b) throws IOException, NullPointerException
write(b, 0,
buf.length)
which is exactly how it is implemented in this
class.b
- The array of bytes to writeIOException
- If an error occursNullPointerException
public void write(byte[] data, int offset, int count) throws IOException, NullPointerException, IndexOutOfBoundsException
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.
data
- The array of bytes to write fromoffset

public void flush() throws IOException
This method in this class does nothing.
IOException
- If an error occurspublic void close() throws IOException
This method in this class does nothing.

- If an error occursprotected void finalize()
Object
The finalize() method of a Class is only called if it overrides finalize() - the finalize() method java.lang.Object is never called by the Eve VM.
