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

This class provides method definitions required to filter data obtained from the InputStream specified when the FilterInputStream is created. It must be subclassed to perform some sort of filtering operation and cannot be instantiated directly. See the subclasses BufferedInputStream, DataInputStream, and PushbackInputStream.

public class 
FilterInputStream  extends InputStream {
// Protected Constructors

in );  
// Public Methods Overriding InputStream
