Modifier and Type | Method and Description |
---|---|
void |
close()
Closes the ZIP output stream as well as the stream being filtered.
|
void |
closeEntry()
Closes the current ZIP entry and positions the stream for writing
the next entry.
|
void |
finish()
Finishes writing the contents of the ZIP output stream without closing
the underlying stream.
|
void |
putNextEntry(ZipEntry e)
Begins writing a new ZIP file entry and positions the stream to the
start of the entry data.
|
void |
setComment(String comment)
Sets the ZIP file comment.
|
void |
setLevel(int level)
Sets the compression level for subsequent entries which are DEFLATED.
|
void |
setMethod(int method)
Sets the default compression method for subsequent entries.
|
void |
write(byte[] b,
int off,
int len)
Writes an array of bytes to the current ZIP entry data.
