Class SchemaServiceClient (2.18.0)

Service for managing Schemas.

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.

Functions

GetSchema(std::string const &, Options)

Gets a Schema.

Parameters
Name	Description
`name`	`std::string const &` Required. The full resource name of the schema, in the format of `projects/{project}/locations/{location}/collections/{collection}/dataStores/{data_store}/schemas/{schema}`.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

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

GetSchema(google::cloud::discoveryengine::v1::GetSchemaRequest const &, Options)

Gets a Schema.

Parameters
Name	Description
`request`	`google::cloud::discoveryengine::v1::GetSchemaRequest 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. In this case, the proto message is a google.cloud.discoveryengine.v1.GetSchemaRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

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

ListSchemas(std::string const &, Options)

Gets a list of Schemas.

Parameters
Name	Description
`parent`	`std::string const &` Required. The parent data store resource name, in the format of `projects/{project}/locations/{location}/collections/{collection}/dataStores/{data_store}`.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns

Type Description

StreamRange< google::cloud::discoveryengine::v1::Schema >

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.cloud.discoveryengine.v1.Schema, or rather, the C++ class generated by Protobuf from that type. Please consult the Protobuf documentation for details on the Protobuf mapping rules.

ListSchemas(google::cloud::discoveryengine::v1::ListSchemasRequest, Options)

Gets a list of Schemas.

Parameters
Name	Description
`request`	`google::cloud::discoveryengine::v1::ListSchemasRequest` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.discoveryengine.v1.ListSchemasRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns

Type Description

StreamRange< google::cloud::discoveryengine::v1::Schema >

CreateSchema(std::string const &, google::cloud::discoveryengine::v1::Schema const &, std::string const &, Options)

Creates a Schema.

Parameters
Name	Description
`parent`	`std::string const &` Required. The parent data store resource name, in the format of `projects/{project}/locations/{location}/collections/{collection}/dataStores/{data_store}`.
`schema`	`google::cloud::discoveryengine::v1::Schema const &` Required. The Schema to create.
`schema_id`	`std::string const &` Required. The ID to use for the Schema, which will become the final component of the [Schema.name][google.cloud.discoveryengine.v1.Schema.name]. This field should conform to RFC-1034 standard with a length limit of 63 characters.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns

Type Description

future< StatusOr< google::cloud::discoveryengine::v1::Schema > >

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.discoveryengine.v1.Schema proto message. The C++ class representing this message is created by Protobuf, using the Protobuf mapping rules.
