Description copied from interface: TypeService

Given a key, this method first checks if a cached map of Type keys -> ids is not empty. If not, it returns a completed future that contains an optional that contains what this key maps to in the cache. If the cache is empty, the method populates the cache with the mapping of all Type keys to ids in the CTP project, by querying the CTP project for all Types.

After that, the method returns a CompletionStage<Optional<String>> in which the result of it's completion could contain an Optional with the id inside of it or an empty Optional if no Channel was found in the CTP project with this key.

Specified by:

fetchCachedTypeId in interface TypeService

Parameters:

key - the key by which a Type id should be fetched from the CTP project.

Returns:

CompletionStage<Optional<String>> in which the result of its completion could contain an Optional with the id inside of it or an empty Optional if no Channel was found in the CTP project with this key.
