Interface MetadataCacheStorage

public interface MetadataCacheStorage

Defines the storage mechanism used to build a MetadataCache. The cache will be used to store resolved dynamic metadata and avoid computing it multiple times.

In case an specific implementation needs to serialize the data prior to storage, they should keep a reference of the MetadataCacheStorageSerializers available in the MetadataCacheStorageFactoryContext when executing MetadataCacheStorageFactory.createMetadataCache(MetadataCacheStorageFactoryContext); In case serializers are used, implementations should follow this rule: If a value was serialized to be stored put(String, Object), it should be deserialized when returned get(String) That means that, weather or not the value was serialized, the following should always be true: storage.put("KEY", object); Object retrievedObject = storage.get("KEY").get(); assert object.getClass().isAssignableFrom(retrievedObject.class) == true

Since:

1.2.2, 1.3.0
