public void setComment(String comment)
- Sets the ZIP file comment. 设置ZIP文件注释。
- Parameters:
comment
- the comment string 注释字符串- Throws:
IllegalArgumentException
- if the length of the specified ZIP file comment is greater than 0xFFFF bytes 如果指定的ZIP文件注释长度大于0xFFFF字节抛出
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. 设置后续项的默认压缩方法。在未指定单个ZIP文件项的压缩方法时使用默认设置,初始设为DEFLATED。
- Parameters:
method
- the default compression method 默认压缩方法- Throws:
IllegalArgumentException
- if the specified compression method is invalid 如果指定的压缩方法无效抛出
setLevel
public void setLevel(int level)
- Sets the compression level for subsequent entries which are DEFLATED. The default setting is DEFAULT_COMPRESSION. 设置后续DEFLATED项的压缩级别。默认设置为DEFAULT_COMPRESSION。

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. 完成ZIP输出流内容的写入,不关闭底层流。当在同一个输出流上连续应用多个过滤器时使用此方法。
- Overrides:
finish
in classDeflaterOutputStream
- Throws:
ZipException
- if a ZIP file error has occurred 如果发生ZIP文件错误抛出IOException
- if an I/O exception has occurred 如果发生I/O错误抛出
close
public void close() throws IOException
- Closes the ZIP output stream as well as the stream being filtered. 关闭ZIP输出流,同时过滤。
