Direct Known Subclasses:

BufferedOutputStream

public class FilterOutputStream
extends java.io.OutputStream

FilteredOutputStream is a class which takes an output stream and filters the output in some way. The filtered view may be a buffered output or one which compresses data before actually writing the bytes. FilterOutputStreams are meant for byte streams.

FilterInputStream

Field Summary

protected java.io.OutputStream

out The target OutputStream for this filter.

Constructor Summary

FilterOutputStream(java.io.OutputStream out)
Constructs a new FilterOutputStream on the OutputStream out.

Method Summary

void	close() Close this FilterOutputStream.
void	flush() Flush this FilterOutputStream to ensure all pending data is sent out to the target OutputStream.
void	write(byte[] buffer) Writes the entire contents of the byte array buffer to this FilterOutputStream.
void	write(byte[] buffer, int offset, int count) Writes count bytes from the byte array buffer starting at offset to this FilterOutputStream.
void	write(int oneByte) Writes the specified byte oneByte to this FilterOutputStream.

out

protected java.io.OutputStream out

The target OutputStream for this filter.

Constructor Detail

FilterOutputStream

public FilterOutputStream(java.io.OutputStream out)

Constructs a new FilterOutputStream on the OutputStream out. All writes are now filtered through this stream.

Parameters:

out - the target OutputStream to filter writes on.

Method Detail

close

public void close()
           throws java.io.IOException

Close this FilterOutputStream. This implementation closes the target stream.

Overrides:

close in class java.io.OutputStream

Throws:

java.io.IOException - If an error occurs attempting to close this stream.

flush

public void flush()
           throws java.io.IOException

Flush this FilterOutputStream to ensure all pending data is sent out to the target OutputStream. This implementation flushes the target OutputStream.

Overrides:

flush in class java.io.OutputStream

Throws:

java.io.IOException - If an error occurs attempting to flush this FilterOutputStream.

write

public void write(byte[] buffer)
           throws java.io.IOException

Writes the entire contents of the byte array buffer to this FilterOutputStream. This implementation writes the buffer to the target stream.

Overrides:

write in class java.io.OutputStream

Parameters:

buffer - the buffer to be written

Throws:

java.io.IOException - If an error occurs attempting to write to this FilterOutputStream.

write

public void write(byte[] buffer,
                  int offset,
                  int count)
           throws java.io.IOException

Writes count bytes from the byte array buffer starting at offset to this FilterOutputStream. This implementation writes the buffer to the target OutputStream.

Overrides:

write in class java.io.OutputStream

Parameters:

buffer - the buffer to be written

offset - offset in buffer to get bytes

count - number of bytes in buffer to write

Throws:

java.io.IOException - If an error occurs attempting to write to this FilterOutputStream.

java.lang.IndexOutOfBoundsException - If offset or count are outside of bounds.

write

public void write(int oneByte)
           throws java.io.IOException

Writes the specified byte oneByte to this FilterOutputStream. Only the low order byte of oneByte is written. This implementation writes the byte to the target OutputStream.

Specified by:

write in class java.io.OutputStream

Parameters:

oneByte - the byte to be written

Throws:

java.io.IOException - If an error occurs attempting to write to this FilterOutputStream.
