readonly PRUint16 compression

The type of compression used for the item. The possible values and their meanings are defined in the zip file specification at http://www.pkware.com/business_and_developers/developer/appnote/

readonly PRUint32 CRC32

The CRC-32 hash of the file in the entry.

readonly PRBool isDirectory

True if the name of the entry ends with '/' and false otherwise.

readonly PRBool isSynthetic

Use this attribute to determine whether this item is an actual zip entry or is one synthesized for part of a real entry's path. A synthesized entry represents a directory within the zip file which has no corresponding entry within the zip file. For example, the entry for the directory foo/ in a zip containing exactly one entry for foo/bar.txt is synthetic. If the zip file contains an actual entry for a directory, this attribute will be false for the nsIZipEntry for that directory. It is impossible for a file to be synthetic.

readonly PRTime lastModifiedTime

The time at which this item was last modified.

readonly PRUint32 realSize

The uncompressed size of the data in the item.

readonly PRUint32 size

The compressed size of the data in the item.
