public class FilterOutputStream
extends OutputStream
Abstract class representing a filtered output stream of bytes. This class is the basis for enhancing output stream functionality. It allows multiple output stream filters to be chained together, each providing additional functionality.

Variable Index

o out
The actual output stream.

Constructor Index

o FilterOutputStream(OutputStream)
Creates an output stream filter.

Method Index

o close()
Closes the stream.
o flush()
Flushes the stream.
o write(byte[])
Writes an array of bytes.
o write(byte[], int, int)
Writes a subarray of bytes.
o write(int)
Writes a byte.

Variables

o out 
  protected OutputStream out
The actual output stream.

Constructors

o FilterOutputStream 
  public FilterOutputStream(OutputStream out)
Creates an output stream filter.
Parameters:
out - the output stream

Methods

o write 
  public void write(int b) throws IOException
Writes a byte. Will block until the byte is actually written.
Parameters:
b - the byte
Throws: IOException
If an I/O error has occurred.
Overrides:
write in class OutputStream
o write 
  public void write(byte b[]) throws IOException
Writes an array of bytes. Will block until the bytes are actually written.
Parameters:
b - the data to be written
Throws: IOException
If an I/O error has occurred.
Overrides:
write in class OutputStream
o write 
  public void write(byte b[],
                    int off,
                    int len) throws IOException
Writes a subarray of bytes. To be efficient it should be overridden in a subclass.
Parameters:
b - the data to be written
off - the start offset in the data
len - the number of bytes that are written
Throws: IOException
If an I/O error has occurred.
Overrides:
write in class OutputStream
o flush 
  public void flush() throws IOException
Flushes the stream. This will write any buffered output bytes.
Throws: IOException
If an I/O error has occurred.
Overrides:
flush in class OutputStream
o close 
  public void close() throws IOException
Closes the stream. This method must be called to release any resources associated with the stream.
Throws: IOException
If an I/O error has occurred.
Overrides:
close in class OutputStream
