- All Implemented Interfaces:
Closeable
,AutoCloseable
A
FilterInputStream2
contains another InputStream
, 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 transform read
calls, you need to override multiple methods. On the other hand,
it is less trappy: a simple implementation that just overrides close
will not force bytes
to be read one-at-a-time.
