Constructor Details

#initialize {|config| ... } ⇒ Client

Create a new Publisher client object.

Examples

To create a new Publisher client with the default configuration:

client = ::Google::Cloud::PubSub::V1::Publisher::Client.new

To create a new Publisher client with a custom configuration:

client = ::Google::Cloud::PubSub::V1::Publisher::Client.new do |config|
  config.timeout = 10.0
end

Yields:

  • (config) —

Instance Method Details

#configure {|config| ... } ⇒ Client::Configuration

Configure the Publisher Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on configure.

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.

Yield Parameters:

Creates the given topic with the given name. See the resource name rules.

Overloads:

  • #create_topic(request, options = nil) ⇒ ::Google::Cloud::PubSub::V1::Topic

    Pass arguments to create_topic via a request object, either of type Topic or an equivalent Hash.

  • #create_topic(name: nil, labels: nil, message_storage_policy: nil, kms_key_name: nil, schema_settings: nil, satisfies_pzs: nil) ⇒ ::Google::Cloud::PubSub::V1::Topic

    Pass arguments to create_topic via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

#delete_topic(request, options = nil) ⇒ ::Google::Protobuf::Empty #delete_topic(topic: nil) ⇒ ::Google::Protobuf::Empty

Deletes the topic with the given name. Returns NOT_FOUND if the topic does not exist. After a topic is deleted, a new topic may be created with the same name; this is an entirely new topic with none of the old configuration or subscriptions. Existing subscriptions to this topic are not deleted, but their topic field is set to _deleted-topic_.

Overloads:

  • #delete_topic(request, options = nil) ⇒ ::Google::Protobuf::Empty

    Pass arguments to delete_topic via a request object, either of type DeleteTopicRequest or an equivalent Hash.

  • #delete_topic(topic: nil) ⇒ ::Google::Protobuf::Empty

    Pass arguments to delete_topic via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.
