Class DictionaryGenerator

java.lang.Object
  pl.kernelpanic.dbmonster.generator.BasicDataGenerator
      pl.kernelpanic.dbmonster.generator.DictionaryGenerator

All Implemented Interfaces:

DataGenerator, Initializable

public class DictionaryGenerator
extends BasicDataGenerator
implements Initializable

The dictionary generator uses external dictionary as the source of test data.

Dictionary is a flat text file. Each line in this file is a dictionary item. Items must be unique! A file may be compressed using ZIP or GZIP algorithm. The extension of the file (.txt, .zip, .gz) decides which compression method is used.

Dictionary files must be encoded in UTF-8.

Properties

dictFile	Absolute or relative to the schema file path to the dictionary.
unique	boolean value which indicates whether generated value should be unique or random (default: false - random item is used).
