Package net.morimekta.providence.testing.generator

Class GeneratorContext<Context extends GeneratorContext<Context>>

  • Type Parameters:
    Context - The context implementation type.
    Direct Known Subclasses:
    GeneratorContext.Simple
    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.
