java.util.concurrent.CompletionStage<java.util.Map<java.lang.String,java.lang.String>>	cacheKeysToIds(java.util.Set<java.lang.String> productKeys) Filters out the keys which are already cached and fetches only the not-cached product keys from the CTP project defined in an injected SphereClient and stores a mapping for every product to id in the cached map of keys -> ids and returns this cached map.

java.util.concurrent.CompletionStage<java.util.Optional<io.sphere.sdk.products.Product>>	fetchProduct(java.lang.String key) Given a product key, this method fetches a product that matches this given key in the CTP project defined in a potentially injected SphereClient.
java.util.concurrent.CompletionStage<java.util.Optional<java.lang.String>>	getIdFromCacheOrFetch(java.lang.String key) Given a key, if it is blank (null/empty), a completed future with an empty optional is returned.
java.util.concurrent.CompletionStage<io.sphere.sdk.products.Product>	updateProduct(io.sphere.sdk.products.Product product, java.util.List<io.sphere.sdk.commands.UpdateAction<io.sphere.sdk.products.Product>> updateActions) Given a Product and a List<UpdateAction<Product>>, this method issues an update request with these update actions on this Product in the CTP project defined in a potentially injected SphereClient.

Method Detail

getIdFromCacheOrFetch

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

Description copied from interface: ProductService

Given a key, if it is blank (null/empty), a completed future with an empty optional is returned. This method then checks if the cached map of product keys -> ids contains the key. If it does, then an optional containing the mapped id is returned. 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 it's completion could contain an Optional with the id inside of it or an empty Optional if no Product was found in the CTP project with this key.

Specified by:

getIdFromCacheOrFetch in interface ProductService

Parameters:

key - the key by which a Product 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 Product was found in the CTP project with this key.

cacheKeysToIds

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

Description copied from interface: ProductService

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

Note: If all the supplied keys are already cached, the cached map is returned right away with no request to CTP.

Specified by:

cacheKeysToIds in interface ProductService

Parameters:

productKeys - the product keys to fetch and cache the ids for.

Returns:

CompletionStage<Map> in which the result of it's completion contains a map of all product keys -> ids

fetchMatchingProductsByKeys

@Nonnull
public java.util.concurrent.CompletionStage<java.util.Set<io.sphere.sdk.products.Product>> fetchMatchingProductsByKeys(@Nonnull
                                                                                                                                java.util.Set<java.lang.String> productKeys)

Description copied from interface: ProductService

Given a Set of product keys, this method fetches a set of all the products, matching this given set of keys in the CTP project, defined in an injected SphereClient. A mapping of the key to the id of the fetched products is persisted in an in-memory map.

Specified by:

fetchMatchingProductsByKeys in interface ProductService

Parameters:

productKeys - set of product keys to fetch matching products by.

Returns:

CompletionStage<Map> in which the result of it's completion contains a Set of all matching products.

fetchProduct

@Nonnull
public java.util.concurrent.CompletionStage<java.util.Optional<io.sphere.sdk.products.Product>> fetchProduct(@Nullable
                                                                                                                      java.lang.String key)

Description copied from interface: ProductService

Given a product key, this method fetches a product that matches this given key in the CTP project defined in a potentially injected SphereClient. If there is no matching product an empty Optional will be returned in the returned future. A mapping of the key to the id of the fetched category is persisted in an in -memory map.

Specified by:

fetchProduct in interface ProductService

Parameters:

key - the key of the product to fetch.

Returns:

CompletionStage<Optional> in which the result of it's completion contains an Optional that contains the matching Product if exists, otherwise empty.

createProduct

@Nonnull
public java.util.concurrent.CompletionStage<java.util.Optional<io.sphere.sdk.products.Product>> createProduct(@Nonnull
                                                                                                                       io.sphere.sdk.products.ProductDraft productDraft)

Description copied from interface: ProductService

Given a resource draft of type ProductDraft, this method attempts to create a resource Product based on it in the CTP project defined by the sync options.

A completion stage containing an empty option and the error callback will be triggered in those cases:

• the draft has a blank key
• the create request fails on CTP

On the other hand, if the resource gets created successfully on CTP, then the created resource's id and key are cached and the method returns a CompletionStage in which the result of it's completion contains an instance Optional of the resource which was created.

Specified by:

createProduct in interface ProductService

Parameters:

productDraft - the resource draft to create a resource based off of.

Returns:

a CompletionStage containing an optional with the created resource if successful otherwise an empty optional.

updateProduct

public java.util.concurrent.CompletionStage<io.sphere.sdk.products.Product> updateProduct(@Nonnull
                                                                                                   io.sphere.sdk.products.Product product,

Description copied from interface: ProductService

Given a Product and a List<UpdateAction<Product>>, this method issues an update request with these update actions on this Product in the CTP project defined in a potentially injected SphereClient.

Specified by:

updateProduct in interface ProductService

Parameters:

product - the Product to update.

updateActions - the update actions to update the Product with.

Returns:

CompletionStage<Product> containing as a result of it's completion an instance of the Product which was updated in the CTP project or a SphereException.
