Class ProxyInputStream

Known Direct Subclasses:
CountingInputStream, SwappedDataInputStream
public abstract class ProxyInputStream
extends FilterInputStream
A Proxy stream which acts as expected, that is it passes the method calls on to the proxied stream and doesn't change which methods are being called.

It is an alternative base class to FilterInputStream to increase reusability, because FilterInputStream changes the methods being called, such as read(byte[]) to read(byte[], int, int).
