Class ObjectIdGenerator

java.lang.Object
  thinkui.datagen.AbstractAttributeValueGenerator
      thinkui.datagen.generators.ObjectIdGenerator

All Implemented Interfaces:

AttributeValueGenerator, java.lang.Cloneable

public class ObjectIdGenerator

extends AbstractAttributeValueGenerator

Implements an AttributeValueGenerator for generating Object ID values. The values will be distributed based on the specified probability model and will be bounded between the optional minimum and maximum values of the attribute value range constraints.
