  extended by cz.cuni.jagrlib.DefaultProperty
      extended by cz.cuni.jagrlib.Piece
          extended by cz.cuni.jagrlib.worker.CompressionWorker
All Implemented Interfaces:
Breakable, Property, Worker, Template, java.lang.Runnable

public class CompressionWorker
extends Piece
implements Worker

Worker: general data compression.

  1. optional preprocessing
  2. compression (mandatory)
  3. decompression = reconstruction
  4. optional saving of reconstructed data (some ordinal file-format)
Another optional plugs: reconstruction error measure, graphics viewer (if apropriate), binary code size (output BitStream).

Since:
0.26

run

public void run()
Executive routine of the working thread.

Specified by:
run in interface java.lang.Runnable

set

public void set(java.lang.String key,
                java.lang.Object value)
Sets the given property.

Specified by:
set in interface Property
Overrides:
set in class DefaultProperty
Parameters:
key - Key string.
value - The new value.
See Also:
