Public Constructors
Constructs a new JarOutputStream using an output stream. The
content of the Manifest must match the JAR entry information
written subsequently to the stream.
Parameters
| os
| the OutputStream to write to |
| mf
| the Manifest to output for this JAR file. |
Throws
| IOException
| if an error occurs creating the JarOutputStream.
|
public
JarOutputStream
(OutputStream os)
Constructs a new JarOutputStream using an arbitrary output
stream.
Parameters
| os
| the OutputStream to write to. |
Throws
| IOException
| if an error occurs creating the JarOutputStream.
|
Public Methods
public
void
putNextEntry
(ZipEntry ze)
Writes the specified ZIP entry to the underlying stream. The previous
entry is closed if it is still open.
Parameters
| ze
| the ZipEntry to write to. |
