Constructor Detail
JarOutputStream
public JarOutputStream(OutputStream out, Manifest man) throws IOException
Creates a new JarOutputStream
with the specified Manifest
. The manifest is written as the first entry to the output stream.
- Parameters:
-
out
- the actual output stream -
man
- the optionalManifest
- Throws:
-
IOException
- if an I/O error has occurred
JarOutputStream
public JarOutputStream(OutputStream out) throws IOException
Creates a new JarOutputStream
with no manifest.
- Parameters:
-
out
- the actual output stream - Throws:
-
IOException
- if an I/O error has occurred
Method Detail
putNextEntry
public void putNextEntry(ZipEntry ze) throws IOException
Begins writing a new JAR file entry and positions the stream to the start of the entry data. This method will also close any previous entry. The default compression method will be used if no compression method was specified for the entry. The current time will be used if the entry has no set modification time.
- Overrides:
-
putNextEntry
in classZipOutputStream
- Parameters:
-
ze
- the ZIP/JAR entry to be written - Throws:
-
ZipException
- if a ZIP error has occurred -
IOException
- if an I/O error has occurred
