Method Summary

Modifier and Type	Method and Description
java.util.concurrent.CompletionStage<java.util.Map<java.lang.String,java.lang.String>>	cacheKeysToIds(java.util.Set<java.lang.String> channelKeys) Filters out the keys which are already cached and fetches only the not-cached channel keys from the CTP project defined in an injected SphereClient and stores a mapping for every channel to id in the cached map of keys -> ids and returns this cached map.
java.util.concurrent.CompletionStage<java.util.Optional<io.sphere.sdk.channels.Channel>>	createAndCacheChannel(java.lang.String key) Creates a new channel with the supplied key and puts a new mapping of it's key to id in a cache map.

Description copied from interface: ChannelService

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

Specified by:

cacheKeysToIds in interface ChannelService

Parameters:

channelKeys - - a set of channel keys to fetch and cache the ids for

Returns:

CompletionStage<Map> in which the result of it's completion contains a map of requested tax channel -> ids

fetchCachedChannelId

@Nonnull
public java.util.concurrent.CompletionStage<java.util.Optional<java.lang.String>> fetchCachedChannelId(@Nonnull
                                                                                                                java.lang.String key)

Description copied from interface: ChannelService

Given a key, this method first checks if a cached map of channel 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 channels' keys to ids in the CTP project, by querying the CTP project channels.

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:

fetchCachedChannelId in interface ChannelService

Parameters:

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

Returns:

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 external id.

createChannel

public java.util.concurrent.CompletionStage<java.util.Optional<io.sphere.sdk.channels.Channel>> createChannel(@Nonnull
                                                                                                                       java.lang.String key)

Description copied from interface: ChannelService

Creates a new channel with the supplied key.

Specified by:

createChannel in interface ChannelService

Parameters:

key - key of supply channel.

Returns:

a future containing as a result the created Channel or a sphere exception.

createAndCacheChannel

@Nonnull
public java.util.concurrent.CompletionStage<java.util.Optional<io.sphere.sdk.channels.Channel>> createAndCacheChannel(@Nonnull
                                                                                                                               java.lang.String key)

Description copied from interface: ChannelService

Creates a new channel with the supplied key and puts a new mapping of it's key to id in a cache map.

Specified by:

createAndCacheChannel in interface ChannelService

Parameters:

key - key of supply channel.

Returns:

a future containing as a result the created Channel or a sphere exception.
