Class Overview

An instance of ZipEntry represents an entry within a ZIP-archive. An entry has attributes such as name (= path) or the size of its data. While an entry identifies data stored in an archive, it does not hold the data itself. For example when reading a ZIP-file you will first retrieve all its entries in a collection and then read the data for a specific entry through an input stream.
