Java in a Nutshell, 5th Edition [Electronic resources]

This class provides method definitions required to filter the data to be written to the OutputStream specified when the FilterOutputStream is created. It must be subclassed to perform some sort of filtering operation and may not be instantiated directly. See the subclasses BufferedOutputStream and DataOutputStream.

public class 
FilterOutputStream  extends OutputStream {
// Public Constructors
public 
FilterOutputStream (OutputStream 
out );  
// Public Methods Overriding OutputStream
public void 
close ( ) throws IOException;  
public void 
flush ( ) throws IOException;  
public void 
write (int 
b ) throws IOException;  
public void 
write (byte[ ] 
b ) throws IOException;  
public void
