Interface RandomizerProvider

public interface RandomizerProvider

Strategy interface to provide randomizers for field/type based on the current context. Implementations may (or may not) use registries to provide randomizers. The added value of this interface compared to a simple RandomizerRegistry is that it gives access to the current context and allows fine grained randomizer selection based on that context.
