Interface DataGenerator

All Known Implementing Classes:

BaseDataGenerator, BooleanGenerator, CollectionGenerator, ComplexObjectGenerator, ConditionalGenerator, DateGenerator, EqualsGenerator, GenGroupGenerator, GroupMemberGenerator, MapGenerator, NumberGenerator, SeriesGenerator, StringGenerator, StringListGenerator

public interface DataGenerator

Creates an object (regular POJO or MetaObject) with the value of the object (or its properties) set according to various rules. The most basic rule is whether the object can be null or not. Implementing classes can add various rules depending on what type of data they are supposed to generate. Examples include:

One and only one specific object

A number (of a designated type) in a specified range

An element of a specified group of objects

An object with some or all of its properties set by sub-generators

A Collection of objects

Callers can pass a context which contains information about the environment in which the object is being created. For example, if the generator is being invoked to set a property of another object, the context should contain the parent object. This is most useful for ConditionalDataGenerators that depend on the value of other properties or even other objects.
