java.lang.Object

org.odpi.openmetadata.adapters.repositoryservices.xtdb.repositoryconnector.cache.ErrorMessageCache

public class ErrorMessageCache
extends Object

A thread-safe way of capturing errors for a given transaction for error-handling purposes across threads. (Basically so we can still throw meaningful errors back to API calls even though the back-end processing happens in a different thread, asynchronously, from the API call itself.)
