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.
