| ZipFile | | public class ZipFile (Code) | | Replacement for java.util.ZipFile.
This class adds support for file name encodings other than UTF-8
(which is required to work on ZIP files created by native zip tools
and is able to skip a preamble like the one found in self
extracting archives. Furthermore it returns instances of
org.apache.tools.zip.ZipEntry instead of
java.util.zip.ZipEntry.
It doesn't extend java.util.zip.ZipFile as it would
have to reimplement all methods anyway. Like
java.util.ZipFile, it uses RandomAccessFile under the
covers and supports compressed and uncompressed entries.
The method signatures mimic the ones of
java.util.zip.ZipFile, with a couple of exceptions:
- There is no getName method.
- entries has been renamed to getEntries.
- getEntries and getEntry return
org.apache.tools.zip.ZipEntry instances.
- close is allowed to throw IOException.

Parameters:
l - contains the stored DOS time. a Date instance corresponding to the given time. |
| getEncoding | | public String getEncoding()(Code) | | The encoding to use for filenames and the file comment.
null if using the platform's default character encoding. |
