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/*

Equality

Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection> objects compare equal. Objects that compare equal share the same underlying resources.

Performance

Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.

Thread Safety

Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.

opts	Options Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
StatusOr< google::cloud::vision::v1::ProductSet >	the result of the RPC. The response message type (google.cloud.vision.v1.ProductSet) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the StatusOr contains the error details.

ImportProductSets(std::string const &, google::cloud::vision::v1::ImportProductSetsInputConfig const &, Options)

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
parent	std::string const & Required. The project in which the ProductSets should be imported. Format is projects/PROJECT_ID/locations/LOC_ID.
input_config	google::cloud::vision::v1::ImportProductSetsInputConfig const & Required. The input content for the list of requests.
opts	Options Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
future< StatusOr< google::cloud::vision::v1::ImportProductSetsResponse > >	A future that becomes satisfied when the LRO (Long Running Operation) completes or the polling policy in effect for this call is exhausted. The future is satisfied with an error if the LRO completes with an error or the polling policy is exhausted. In this case the StatusOr returned by the future contains the error. If the LRO completes successfully the value of the future contains the LRO's result. For this RPC the result is a google.cloud.vision.v1.ImportProductSetsResponse proto message. The C++ class representing this message is created by Protobuf, using the Protobuf mapping rules.

Returns
Type	Description
future< StatusOr< google::cloud::vision::v1::ImportProductSetsResponse > >	A future that becomes satisfied when the LRO (Long Running Operation) completes or the polling policy in effect for this call is exhausted.

If the LRO completes successfully the value of the future contains the LRO's result. For this RPC the result is a google.cloud.vision.v1.ImportProductSetsResponse proto message. The C++ class representing this message is created by Protobuf, using the Protobuf mapping rules.

PurgeProducts(std::string const &, Options)

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
parent	std::string const & Required. The project and location in which the Products should be deleted. Format is projects/PROJECT_ID/locations/LOC_ID.
