Package net.morimekta.providence.testing.generator

Class GeneratorContext<Context extends GeneratorContext<Context>>

java.lang.Object

net.morimekta.providence.testing.generator.GeneratorContext<Context>

Type Parameters:

Context - The context implementation type.

Direct Known Subclasses:

GeneratorContext.Simple, SimpleGeneratorWatcher.Context

public class GeneratorContext<Context extends GeneratorContext<Context>>
extends java.lang.Object

This is the core generator context, which essentially brings all things to be generated together. It has full knowledge about all the generators, where state is more or less copied from parent generators. And the current generating context.

Constructor Detail

GeneratorContext

public GeneratorContext()

Create a fresh generator.

GeneratorContext

protected GeneratorContext(GeneratorContext<Context> parent)

Create a generator instance as copy of another instance. The new generator can then be updated without interfering with the parent.

Parameters:

parent - The parent generator instance.
