public class FilterInputStream2 extends InputStream
AFilterInputStream2
contains anotherInputStream
, which it uses as its basic source of data, possibly transforming the data along the way or providing additional functionality.Note: unlike
FilterInputStream
this class delegates every method by default. This means to transformread
calls, you need to override multiple methods. On the other hand, it is less trappy: a simple implementation that just overridesclose
will not force bytes to be read one-at-a-time.
