## Interface CacheTopologyValidatorProvider

- All Superinterfaces:
    Extension

      public interface CacheTopologyValidatorProvider
      extends Extension

  The `CacheTopologyValidatorProvider` is used to pass an implementation of `TopologyValidator`s for a specific cache through Ignite plugin extensions mechanism. Each cache, on startup, iterates over all registered `CacheTopologyValidatorProvider`s and tries to obtain the instance of `TopologyValidator` by cache name. All obtained `TopologyValidator`s are saved in the cache context and successively called during topology validation process. The topology validation is passed if all `TopologyValidator`s consider that the current topology is valid.
