Public Constructors
public
ZipOutputStream(OutputStream p1)
Constructs a new ZipOutputStream on p1
Parameters
p1
| OutputStream The InputStream to output to
|
Public Methods
public
void
close()
Closes the current ZipEntry if any. Closes the underlying output stream.
If the stream is already closed this method does nothing.
public
void
closeEntry()
Closes the current ZipEntry. Any entry terminal data is written to the
underlying stream.
public
void
finish()
Indicates that all entries have been written to the stream. Any terminal
ZipFile information is written to the underlying stream.
public
void
putNextEntry(ZipEntry ze)
Writes entry information for ze to the underlying stream. Data associated
with the entry can then be written using write(). After data is written
closeEntry() must be called to complete the storing of ze on the
underlying stream.
public
void
setComment(String comment)
Sets the ZipFile comment associated with the file being written.
public
void
setLevel(int level)
Sets the compression level to be used for writing entry data. This level
may be set on a per entry basis. level must have a value between 0 and
10.
public
void
setMethod(int method)
Sets the compression method to be used when compressing entry data.
method must be one of STORED or DEFLATED.
Parameters
method
| Compression method to use
|
public
void
write(byte[] buffer, int off, int nbytes)
Writes data for the current entry to the underlying stream.
Parameters
buffer
| Buffer of data to compress |
off
| offset in buffer to extract data from |
nbytes
| Number of bytes of data to compress and write |
