public class FilterOutputStream

extends OutputStream

A FilterOutputStream contains another output stream, which it uses as its basic data drain, possibly transforming the data before it is written to the stream.

Constructor Summary

FilterOutputStream(OutputStream os)
Creates a new instance of FilterOutputStream.

Method Summary

void	close() Closes the underlying output stream and releases all system resources associated with it.
void	flush() Flushes the underlying output stream.
void	write(byte[] b) Writes b.length bytes from b to the underlying output stream.
void	write(byte[] b, int off, int len) Writes len bytes from b to the underlying output stream starting at offset off.
void	write(int i) Writes a single byte to the underlying output stream.

Constructor Detail

FilterOutputStream

public FilterOutputStream(OutputStream os)

Creates a new instance of FilterOutputStream. The passed output stream is stored and used for output.

Parameters:

os - Output stream to write data to.

Method Detail

write

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

Writes len bytes from b to the underlying output stream starting at offset off.

Overrides:

write in class OutputStream

Parameters:

b - Array of bytes containing the data to be written.

off - Offset into b where the data begins.

len - Number of bytes to be written.

Throws:

IOException - if an I/O error occures.

close

public void close()
           throws IOException

Closes the underlying output stream and releases all system resources associated with it.

Overrides:

close in class OutputStream

IOException

flush

public void flush()
           throws IOException

Flushes the underlying output stream.

Overrides:

flush in class OutputStream

IOException

write

public void write(byte[] b)
           throws IOException

Writes b.length bytes from b to the underlying output stream.

Overrides:

write in class OutputStream

Parameters:

b - Array of bytes containing the data to be written.

Throws:

IOException - if an I/O error occures.

write

public void write(int i)
           throws IOException

Writes a single byte to the underlying output stream.

Specified by:

write in class OutputStream

Parameters:

i - The byte of data to write.

Throws:

IOException - if an I/O error occures.
