cache

protected final ZipCloseableDirectory cache

The closeable directory that caches the open ZipFile

Constructor Detail

ZipFileImpl

public ZipFileImpl(File zip1,
                   ZipEntry entry1,
                   ZipDirectory parent1,
                   ZipCloseableDirectory cache)

This constructor is used to create a file entry within the zip.

Parameters:

zip1 - the zip file the entry is in.

entry1 - the entry this IFile represents.

parent1 - the parent directory.

ZipFileImpl

protected ZipFileImpl(File zip1,
                      IDirectory parent)
               throws MalformedURLException

This is called to construct the root directory of the zip.

Parameters:

zip1 - the zip file this represents.

fs - the file on the fs.

rootName - the name of this zipfile relative to the IFile filesystem root

Throws:

MalformedURLException

ZipFileImpl

public ZipFileImpl(ZipFileImpl other,
