Class StringGenerator

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

All Implemented Interfaces:

AttributeValueGenerator, java.lang.Cloneable

Direct Known Subclasses:

PasswordGenerator

public class StringGenerator

extends AbstractAttributeValueGenerator

Implements an AttributeValueGenerator for generating String values. If the attribute specified has a preferred width, that value will be configured as the mean length. The actual length of the generated values will be distributed based on the specified probability model and will be bounded between the optional minimum and maximum length of the attribute string length constraints. Otherwise, a default minimum and maximum string length will be used.
