    • Method Detail

      • getCompressionProgressed

        public Event<ProgressEventArgs> getCompressionProgressed()

        Gets an event that is raised when a portion of raw stream compressed. 

        
     File source = new File("huge.bin");
     Bzip2SaveOptions settings = new Bzip2SaveOptions();
     settings.setCompressionProgressed((sender, args) -> {
         int percent = (int)((100 * args.getProceededBytes()) / source.length());
     });

        This event won't be raised when compressing in multithreaded mode.

        Returns:
        an event that is raised when a portion of raw stream compressed

      • setCompressionProgressed

        public void setCompressionProgressed​(Event<ProgressEventArgs> value)

        Sets an event that is raised when a portion of raw stream compressed. 

        
     File source = new File("huge.bin");
     Bzip2SaveOptions settings = new Bzip2SaveOptions();
     settings.setCompressionProgressed((sender, args) -> {
         int percent = (int)((100 * args.getProceededBytes()) / source.length());
     });

        This event won't be raised when compressing in multithreaded mode.

        Parameters:
        value - an event that is raised when a portion of raw stream compressed

      • getBlockSize

        public final int getBlockSize()

        Block size in hundreds of kilobytes.

        Returns:
        block size in hundreds of kilobytes

      • getCompressionThreads

        public final int getCompressionThreads()

        Gets compression thread count. If the value is greater than 1, multithreading compression will be used.

        Returns:
        compression thread count.

      • setCompressionThreads

        public final void setCompressionThreads​(int value)

        Sets compression thread count. If the value is greater than 1, multithreading compression will be used.

        Parameters:
        value - compression thread count.
