Interface ValidatorRegistry<K>

Type Parameters:

K - validator key

All Superinterfaces:

AutoCloseable, Map<K,Validator>, Service, StaticService

public interface ValidatorRegistry<K>
extends Map<K,Validator>, StaticService

Registry to cache validators in memory.

The registry contains two caches:

• static - which keeps all the validators in the cache for the entire lifecycle
• dynamic - which keeps the validators in a
  invalid reference

  org.apache.camel.support.LRUCache

  and may evict validators which hasn't been requested recently

The static cache stores all the validators that are created as part of setting up and starting routes. The static cache has no upper limit.

The dynamic cache stores the validators that are created and used ad-hoc, such as from custom Java code that creates new validators etc. The dynamic cache has an upper limit, that by default is 1000 entries.
