Method Detail

cacheKeysToIds

@Nonnull
java.util.concurrent.CompletionStage<java.util.Map<java.lang.String,java.lang.String>> cacheKeysToIds(@Nonnull
                                                                                                               java.util.Set<java.lang.String> customerGroupKeys)

Filters out the keys which are already cached and fetches only the not-cached customer group keys from the CTP project defined in an injected SphereClient and stores a mapping for every customer group to id in the cached map of keys -> ids and returns this cached map.

Parameters:

customerGroupKeys - - a set customer group keys to fetch and cache the ids for

Returns:

CompletionStage<Map> in which the result of it's completion contains a map of requested customer group keys -> ids

fetchCachedCustomerGroupId

@Nonnull
java.util.concurrent.CompletionStage<java.util.Optional<java.lang.String>> fetchCachedCustomerGroupId(@Nullable
                                                                                                               java.lang.String key)

Given a key, this method first checks if a cached map of customer group keys -> ids contains the key. If not, it returns a completed future that contains an Optional that contains what this key maps to in the cache. If the cache doesn't contain the key; this method attempts to fetch the id of the key from the CTP project, caches it and returns a 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 CustomerGroup was found in the CTP project with this key.

Parameters:

key - the key by which a CustomerGroup 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 CustomerGroup was found in the CTP project with this key or a blank (null/empty string) key was supplied.
