Constructor Detail

• ZipOutputStream

  public ZipOutputStream​(OutputStream out)

  Creates a new ZIP output stream.

  The UTF-8 charset is used to encode the entry names and comments.

  Parameters:

  out - the actual output stream

• ZipOutputStream

  public ZipOutputStream​(OutputStream out,
                         Charset charset)

  Creates a new ZIP output stream.

  Parameters:

  out - the actual output stream

  charset - the charset to be used to encode the entry names and comments

  Since:

  1.7

Method Detail

• setComment

  public void setComment​(String comment)

  Sets the ZIP file comment.

  Parameters:

  comment - the comment string

  Throws:

  IllegalArgumentException - if the length of the specified ZIP file comment is greater than 0xFFFF bytes

• setMethod

  public void setMethod​(int method)

  Sets the default compression method for subsequent entries. This default will be used whenever the compression method is not specified for an individual ZIP file entry, and is initially set to DEFLATED.

  Parameters:

  method - the default compression method

  Throws:

  IllegalArgumentException - if the specified compression method is invalid

• setLevel

  public void setLevel​(int level)

  Sets the compression level for subsequent entries which are DEFLATED. The default setting is DEFAULT_COMPRESSION.

  Parameters:

  level - the compression level (0-9)

  Throws:

  IllegalArgumentException - if the compression level is invalid

• putNextEntry

  public void putNextEntry​(ZipEntry e)
                    throws IOException

  Begins writing a new ZIP file entry and positions the stream to the start of the entry data. Closes the current entry if still active. The default compression method will be used if no compression method was specified for the entry, and the current time will be used if the entry has no set modification time.

  Parameters:

  e - the ZIP entry to be written

  Throws:

  ZipException - if a ZIP format error has occurred

  IOException - if an I/O error has occurred

• closeEntry

  public void closeEntry()
                  throws IOException

  Closes the current ZIP entry and positions the stream for writing the next entry.

  Throws:

  ZipException - if a ZIP format error has occurred

  IOException - if an I/O error has occurred

• write

  public void write​(byte[] b,
                    int off,
                    int len)
             throws IOException

  Writes an array of bytes to the current ZIP entry data. This method will block until all the bytes are written.

  Overrides:

  write in class DeflaterOutputStream

  Parameters:

  b - the data to be written

  off - the start offset in the data

  len - the number of bytes that are written

  Throws:

  ZipException - if a ZIP file error has occurred

  IOException - if an I/O error has occurred

  See Also:

  FilterOutputStream.write(int)

• finish

  public void finish()
              throws IOException

  Finishes writing the contents of the ZIP output stream without closing the underlying stream. Use this method when applying multiple filters in succession to the same output stream.

  Overrides:

  finish in class DeflaterOutputStream

  Throws:

  ZipException - if a ZIP file error has occurred

  IOException - if an I/O exception has occurred

• close

  public void close()
             throws IOException

  Closes the ZIP output stream as well as the stream being filtered.

  Specified by:

  close in interface AutoCloseable

  Specified by:

  close in interface Closeable

  Overrides:

  close in class DeflaterOutputStream

  Throws:

  ZipException - if a ZIP file error has occurred

  IOException - if an I/O error has occurred
