java.lang.Object
  java.io.InputStream
      dk.rode.thesis.templatemethod.ZipSequence.ReadOnlyInputStream

All Implemented Interfaces:

Closeable

Enclosing class:

ZipSequence

 class ZipSequence.ReadOnlyInputStream
extends InputStream

A read-only input stream is a protection proxy (decorator) that ensures that a given input stream cannot be closed or reset by an external context.

Implementation notes:
This is an application of the Proxy pattern.
