FilterWriter
extends Writer
Abstract class for writing filtered character streams.
The abstract class FilterWriter itself
provides default methods that pass all requests to the
contained stream. Subclasses of FilterWriter
should override some of these methods and may also
provide additional methods and fields.

Fields
out
Writer out
The underlying character-output stream.
Protected constructors
FilterWriter
FilterWriter (Writer out)
Create a new filtered writer.
| Parameters |

out |
Writer:
a Writer object to provide the underlying stream. |
Public methods
close
void close ()
Closes the stream, flushing it first. Once the stream has been closed,
further write() or flush() invocations will cause an IOException to be
thrown. Closing a previously closed stream has no effect.
flush
void flush ()
Flushes the stream.
write
void write (int c)
Writes a single character.
| Parameters |
|---|
c |
int:
int specifying a character to be written |
write
void write (String str,
int off,
int len)
Writes a portion of a string.
| Parameters |
|---|
str |
String:
String to be written |
off |
int:
Offset from which to start reading characters |
len |
int:
Number of characters to be written |
write
void write (char[] cbuf,
int off,
int len)
Writes a portion of an array of characters.
| Parameters |
|---|
cbuf |
char:
Buffer of characters to be written |
off |
int:
Offset from which to start reading characters |
len |
int:
Number of characters to be written |
