Functions

MakeBlockingPublisherConnection(Options)

Creates a new BlockingPublisherConnection object to work with BlockingPublisher.

The BlockingPublisherConnection class is provided for applications wanting to mock the BlockingPublisher behavior in their tests. It is not intended for direct use.

Performance

Creating a new BlockingPublisherConnection is relatively expensive. This typically initiates connections to the service, and therefore these objects should be shared and reused when possible. Note that gRPC reuses existing OS resources (sockets) whenever possible, so applications may experience better performance on the second (and subsequent) calls to this function with the same Options from GrpcOptionList and CommonOptionList. However, this behavior is not guaranteed and applications should not rely on it.

BlockingPublisherConnection

Parameter
Name Description
opts

The options to use for this call. Expected options are any of the types in the following option lists.

Returns
Type Description
std::shared_ptr< BlockingPublisherConnection >

MakePublisherConnection(Topic, std::initializer_list< internal::NonConstructible >)

Creates a new PublisherConnection object to work with Publisher.

Parameters
Name Description
topic

Returns
Type Description
std::shared_ptr< PublisherConnection >

MakePublisherConnection(Topic, Options)

Creates a new PublisherConnection object to work with Publisher.

The PublisherConnection class is provided for applications wanting to mock the Publisher behavior in their tests. It is not intended for direct use.

Performance

Creating a new PublisherConnection is relatively expensive. This typically initiates connections to the service, and therefore these objects should be shared and reused when possible. Note that gRPC reuses existing OS resources (sockets) whenever possible, so applications may experience better performance on the second (and subsequent) calls to this function with the same Options from GrpcOptionList and CommonOptionList.

PublisherConnection

Parameters
Name Description
topic

the Cloud Pub/Sub topic used by the returned PublisherConnection.

opts

The options to use for this call. Expected options are any of the types in the following option lists.

Returns
Type Description
std::shared_ptr< PublisherConnection >

MakePublisherConnection(Topic, PublisherOptions, ConnectionOptions, std::unique_ptr< RetryPolicy const >, std::unique_ptr< BackoffPolicy const >)

Creates a new PublisherConnection object to work with Publisher.

The PublisherConnection class is not intended for direct use in applications, it is provided for applications wanting to mock the Publisher behavior in their tests.

Performance

Creating a new PublisherConnection is relatively expensive. This typically initiate connections to the service, and therefore these objects should be shared and reused when possible. Note that gRPC reuses existing OS resources (sockets) whenever possible, so applications may experience better performance on the second (and subsequent) calls to this function with the identical values for options. However, this behavior is not guaranteed and applications should not rely on it.
