Class EventarcClient (2.22.0)

Eventarc allows users to subscribe to various events that are provided by Google Cloud services and forward them to supported destinations.

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.

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

DeleteChannelConnection(google::cloud::eventarc::v1::DeleteChannelConnectionRequest const &, Options)

Delete a single ChannelConnection.

Parameters
Name	Description
`request`	`google::cloud::eventarc::v1::DeleteChannelConnectionRequest 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.eventarc.v1.DeleteChannelConnectionRequest. 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

future< StatusOr< google::cloud::eventarc::v1::ChannelConnection > >

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

GetGoogleChannelConfig(std::string const &, Options)

Get a GoogleChannelConfig.

Parameters
Name	Description
`name`	`std::string const &` Required. The name of the config to get.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

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

GetGoogleChannelConfig(google::cloud::eventarc::v1::GetGoogleChannelConfigRequest const &, Options)

Get a GoogleChannelConfig.

Parameters
Name	Description
`request`	`google::cloud::eventarc::v1::GetGoogleChannelConfigRequest 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.eventarc.v1.GetGoogleChannelConfigRequest. 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::eventarc::v1::GoogleChannelConfig >`	the result of the RPC. The response message type (google.cloud.eventarc.v1.GoogleChannelConfig) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

UpdateGoogleChannelConfig(google::cloud::eventarc::v1::GoogleChannelConfig const &, google::protobuf::FieldMask const &, Options)

Update a single GoogleChannelConfig.

Parameters
Name	Description
`google_channel_config`	`google::cloud::eventarc::v1::GoogleChannelConfig const &` Required. The config to be updated.
`update_mask`	`google::protobuf::FieldMask const &` The fields to be updated; only fields explicitly provided are updated. If no field mask is provided, all provided fields in the request are updated. To update all fields, provide a field mask of "*".
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

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

UpdateGoogleChannelConfig(google::cloud::eventarc::v1::UpdateGoogleChannelConfigRequest const &, Options)

Update a single GoogleChannelConfig.

Parameters
Name	Description
`request`	`google::cloud::eventarc::v1::UpdateGoogleChannelConfigRequest 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.eventarc.v1.UpdateGoogleChannelConfigRequest. 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::eventarc::v1::GoogleChannelConfig >`	the result of the RPC. The response message type (google.cloud.eventarc.v1.GoogleChannelConfig) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.
