+----java.io.FilterOutputStream
The class FilterOutputStream itself simply overrides
all methods of OutputStream with versions that pass
all requests to the underlying output stream. Subclasses of
FilterOutputStream may further override some of these
methods as well as provide additional methods and fields.
b.length bytes to this output stream.
len bytes from the specified
byte array starting at offset off to
this output stream.
byte to this output stream.
protected OutputStream out
public FilterOutputStream(OutputStream out)
public void write(int b) throws IOException
byte to this output stream.
The write method of FilterOutputStream
calls the write method of its underlying output stream.
byte.
public void write(byte b[]) throws IOException
b.length bytes to this output stream.
The write method of FilterOutputStream
calls its write method of three arguments with the
arguments b, 0, and
b.length.
Note that this method does not call the one-argument
write method of its underlying stream with the single
argument b.
public void write(byte b[],
int off,
int len) throws IOException
len bytes from the specified
byte array starting at offset off to
this output stream.
The write method of FilterOutputStream
calls the write method of one argument on each
byte to output.
Note that this method does not call the write method
of its underlying input stream with the same arguments. Subclasses
of FilterOutputStream should provide a more efficient
implementation of this method.
public void flush() throws IOException
The flush method of FilterOutputStream
calls the flush method of its underlying output stream.
public void close() throws IOException
The close method of FilterOutputStream
calls its flush method, and then calls the
close method of its underlying output stream.
