Field Detail
DEFLATED
final public static int DEFLATED(Code)
Method for compressed entries



STORED
final public static int STORED(Code)
Method for uncompressed entries



ZIPDataDescriptorFlag
final static int ZIPDataDescriptorFlag(Code)



ZIPLocalHeaderVersionNeeded
final static int ZIPLocalHeaderVersionNeeded(Code)




Constructor Detail
ZipOutputStream
public ZipOutputStream(OutputStream p1)(Code)
Constructs a new ZipOutputStream on p1
Parameters:
  p1 - OutputStream The InputStream to output to




Method Detail
close
public void close() throws IOException(Code)
Closes the current ZipEntry if any. Closes the underlying output stream. If the stream is already closed this method does nothing.
exception:
  IOException - If an error occurs closing the stream



closeEntry
public void closeEntry() throws IOException(Code)
Closes the current ZipEntry. Any entry terminal data is written to the underlying stream.
exception:
  IOException - If an error occurs closing the entry



finish
public void finish() throws IOException(Code)
Indicates that all entries have been written to the stream. Any terminal ZipFile information is written to the underlying stream.
exception:
  IOException - If an error occurs while finishing



putNextEntry
public void putNextEntry(ZipEntry ze) throws java.io.IOException(Code)
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.
Parameters:
  ze - ZipEntry to store
exception:
  IOException - If an error occurs storing the entry
See Also:   ZipOutputStream.write



setComment
public void setComment(String comment)(Code)
Sets the ZipFile comment associated with the file being written.
Parameters:
  comment - the file comment



setLevel
public void setLevel(int level)(Code)
Sets the compression level to be used for writing entry data. This level may be set on a per entry basis.
Parameters:
  level - the compression level, must have a value between 0 and 10.



setMethod
public void setMethod(int method)(Code)
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



toUTF8Bytes
static byte[] toUTF8Bytes(String value, int length)(Code)



utf8Count
static int utf8Count(String value)(Code)



write
public void write(byte[] buffer, int off, int nbytes) throws java.io.IOException(Code)
Writes data for the current entry to the underlying stream.
exception:
  IOException - If an error occurs writing to the stream
