Class UserEventServiceClient (2.33.0-rc)

Service for ingesting end user actions on the customer website.

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.

Writes a single user event.

Parameters
Name	Description
`request`	`google::cloud::retail::v2::WriteUserEventRequest const &` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC.

Returns
Type	Description
`StatusOr< google::cloud::retail::v2::UserEvent >`	the result of the RPC. The response message type (google.cloud.retail.v2.UserEvent) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

CollectUserEvent(google::cloud::retail::v2::CollectUserEventRequest const &, Options)

Writes a single user event from the browser.

This uses a GET request to due to browser restriction of POST-ing to a 3rd party domain.

This method is used only by the Retail API JavaScript pixel and Google Tag Manager. Users should not call this method directly.

PurgeUserEvents(google::cloud::retail::v2::PurgeUserEventsRequest const &, Options)

Deletes permanently all user events specified by the filter provided.

Depending on the number of events specified by the filter, this operation could take hours or days to complete. To test a filter, use the list command first.

Type Description

future< StatusOr< google::cloud::retail::v2::PurgeUserEventsResponse > >

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.retail.v2.PurgeUserEventsResponse proto message. The C++ class representing this message is created by Protobuf, using the Protobuf mapping rules.

PurgeUserEvents(NoAwaitTag, google::cloud::retail::v2::PurgeUserEventsRequest const &, Options)

Deletes permanently all user events specified by the filter provided.

Specifying the NoAwaitTag immediately returns the [google::longrunning::Operation] that corresponds to the Long Running Operation that has been started. No polling for operation status occurs.

Type Description

StreamRange< google::longrunning::Operation >

a StreamRange to iterate of the results. See the documentation of this type for details. In brief, this class has begin() and end() member functions returning a iterator class meeting the input iterator requirements. The value type for this iterator is a StatusOr as the iteration may fail even after some values are retrieved successfully, for example, if there is a network disconnect. An empty set of results does not indicate an error, it indicates that there are no resources meeting the request criteria. On a successful iteration the StatusOr<T> contains elements of type google.longrunning.Operation, or rather, the C++ class generated by Protobuf from that type. Please consult the Protobuf documentation for details on the Protobuf mapping rules.

ListOperations(google::longrunning::ListOperationsRequest, Options)

Lists operations that match the specified filter in the request.

Parameters
Name	Description
`request`	`google::longrunning::ListOperationsRequest` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC.
