public static interface ProductSearchGrpc.AsyncService

Manages Products and ProductSets of reference images for use in product search. It uses the following resource model:

• The API has a collection of ProductSet resources, named projects/*/locations/*/productSets/*, which acts as a way to put different products into groups to limit identification. In parallel,
• The API has a collection of Product resources, named projects/*/locations/*/products/*
• Each Product has a collection of ReferenceImage resources, named projects/*/locations/*/products/*/referenceImages/*

Methods

addProductToProductSet(AddProductToProductSetRequest request, StreamObserver<Empty> responseObserver)

public default void addProductToProductSet(AddProductToProductSetRequest request, StreamObserver<Empty> responseObserver)

Adds a Product to the specified ProductSet. If the Product is already present, no change is made. One Product can be added to at most 100 ProductSets. Possible errors:

• Returns NOT_FOUND if the Product or the ProductSet doesn't exist.

Parameters
Name	Description
request	AddProductToProductSetRequest
responseObserver	io.grpc.stub.StreamObserver<Empty>

createProduct(CreateProductRequest request, StreamObserver<Product> responseObserver)

public default void createProduct(CreateProductRequest request, StreamObserver<Product> responseObserver)

Creates and returns a new product resource. Possible errors:

• Returns INVALID_ARGUMENT if display_name is missing or longer than 4096 characters.
• Returns INVALID_ARGUMENT if description is longer than 4096 characters.
• Returns INVALID_ARGUMENT if product_category is missing or invalid.

Parameters
Name	Description
request	CreateProductRequest
responseObserver	io.grpc.stub.StreamObserver<Product>

createProductSet(CreateProductSetRequest request, StreamObserver<ProductSet> responseObserver)

public default void createProductSet(CreateProductSetRequest request, StreamObserver<ProductSet> responseObserver)

Creates and returns a new ProductSet resource. Possible errors:

• Returns INVALID_ARGUMENT if display_name is missing, or is longer than 4096 characters.

Parameters
Name	Description
request	CreateProductSetRequest
responseObserver	io.grpc.stub.StreamObserver<ProductSet>

createReferenceImage(CreateReferenceImageRequest request, StreamObserver<ReferenceImage> responseObserver)

public default void createReferenceImage(CreateReferenceImageRequest request, StreamObserver<ReferenceImage> responseObserver)

Creates and returns a new ReferenceImage resource. The bounding_poly field is optional. If bounding_poly is not specified, the system will try to detect regions of interest in the image that are compatible with the product_category on the parent product. If it is specified, detection is ALWAYS skipped. The system converts polygons into non-rotated rectangles. Note that the pipeline will resize the image if the image resolution is too large to process (above 50MP). Possible errors:

• Returns INVALID_ARGUMENT if the image_uri is missing or longer than 4096 characters.
• Returns INVALID_ARGUMENT if the product does not exist.
• Returns INVALID_ARGUMENT if bounding_poly is not provided, and nothing compatible with the parent product's product_category is detected.
• Returns INVALID_ARGUMENT if bounding_poly contains more than 10 polygons.

Parameters
Name	Description
request	CreateReferenceImageRequest
responseObserver	io.grpc.stub.StreamObserver<ReferenceImage>

deleteProduct(DeleteProductRequest request, StreamObserver<Empty> responseObserver)

public default void deleteProduct(DeleteProductRequest request, StreamObserver<Empty> responseObserver)

deleteProductSet(DeleteProductSetRequest request, StreamObserver<Empty> responseObserver)

public default void deleteProductSet(DeleteProductSetRequest request, StreamObserver<Empty> responseObserver)

deleteReferenceImage(DeleteReferenceImageRequest request, StreamObserver<Empty> responseObserver)

public default void deleteReferenceImage(DeleteReferenceImageRequest request, StreamObserver<Empty> responseObserver)

importProductSets(ImportProductSetsRequest request, StreamObserver<Operation> responseObserver)

public default void importProductSets(ImportProductSetsRequest request, StreamObserver<Operation> responseObserver)

Asynchronous API that imports a list of reference images to specified product sets based on a list of image information. The google.longrunning.Operation API can be used to keep track of the progress and results of the request. Operation.metadata contains BatchOperationMetadata. (progress) Operation.response contains ImportProductSetsResponse. (results) The input source of this method is a csv file on Google Cloud Storage. For the format of the csv file please see ImportProductSetsGcsSource.csv_file_uri.

Parameters
Name	Description
request	ImportProductSetsRequest
responseObserver	io.grpc.stub.StreamObserver<Operation>

listProductSets(ListProductSetsRequest request, StreamObserver<ListProductSetsResponse> responseObserver)

public default void listProductSets(ListProductSetsRequest request, StreamObserver<ListProductSetsResponse> responseObserver)

Lists ProductSets in an unspecified order. Possible errors:

• Returns INVALID_ARGUMENT if page_size is greater than 100, or less than 1.

Parameters
Name	Description
request	ListProductSetsRequest
responseObserver	io.grpc.stub.StreamObserver<ListProductSetsResponse>

listProducts(ListProductsRequest request, StreamObserver<ListProductsResponse> responseObserver)

public default void listProducts(ListProductsRequest request, StreamObserver<ListProductsResponse> responseObserver)

Lists products in an unspecified order. Possible errors:

• Returns INVALID_ARGUMENT if page_size is greater than 100 or less than 1.

Parameters
Name	Description

• Returns INVALID_ARGUMENT if page_size is greater than 100 or less than 1.

Parameters
Name	Description
request	ListProductsInProductSetRequest
responseObserver	io.grpc.stub.StreamObserver<ListProductsInProductSetResponse>

listReferenceImages(ListReferenceImagesRequest request, StreamObserver<ListReferenceImagesResponse> responseObserver)

public default void listReferenceImages(ListReferenceImagesRequest request, StreamObserver<ListReferenceImagesResponse> responseObserver)

responseObserver	io.grpc.stub.StreamObserver<ListReferenceImagesResponse>

purgeProducts(PurgeProductsRequest request, StreamObserver<Operation> responseObserver)

public default void purgeProducts(PurgeProductsRequest request, StreamObserver<Operation> responseObserver)

Asynchronous API to delete all Products in a ProductSet or all Products that are in no ProductSet. If a Product is a member of the specified ProductSet in addition to other ProductSets, the Product will still be deleted. It is recommended to not delete the specified ProductSet until after this operation has completed. It is also recommended to not add any of the Products involved in the batch delete to a new ProductSet while this operation is running because those Products may still end up deleted. It's not possible to undo the PurgeProducts operation. Therefore, it is recommended to keep the csv files used in ImportProductSets (if that was how you originally built the Product Set) before starting PurgeProducts, in case you need to re-import the data after deletion. If the plan is to purge all of the Products from a ProductSet and then re-use the empty ProductSet to re-import new Products into the empty ProductSet, you must wait until the PurgeProducts operation has finished for that ProductSet. The google.longrunning.Operation API can be used to keep track of the progress and results of the request. Operation.metadata contains BatchOperationMetadata. (progress)

Parameters
Name	Description
request	PurgeProductsRequest
responseObserver	io.grpc.stub.StreamObserver<Operation>

removeProductFromProductSet(RemoveProductFromProductSetRequest request, StreamObserver<Empty> responseObserver)

public default void removeProductFromProductSet(RemoveProductFromProductSetRequest request, StreamObserver<Empty> responseObserver)

Removes a Product from the specified ProductSet.

Parameters
Name	Description
request	RemoveProductFromProductSetRequest
responseObserver	io.grpc.stub.StreamObserver<Empty>

updateProduct(UpdateProductRequest request, StreamObserver<Product> responseObserver)

public default void updateProduct(UpdateProductRequest request, StreamObserver<Product> responseObserver)

Makes changes to a Product resource. Only the display_name, description, and labels fields can be updated right now. If labels are updated, the change will not be reflected in queries until the next index time. Possible errors:

• Returns NOT_FOUND if the Product does not exist.
• Returns INVALID_ARGUMENT if display_name is present in update_mask but is missing from the request or longer than 4096 characters.
• Returns INVALID_ARGUMENT if description is present in update_mask but is longer than 4096 characters.
