Overview

Client for the Publisher service.

Eventarc processes events generated by an event provider and delivers them to a subscriber.

An event provider is a software-as-a-service (SaaS) system or product that can generate and deliver events through Eventarc.

A third-party event provider is an event provider from outside of Google.

A partner is a third-party event provider that is integrated with Eventarc.

A subscriber is a GCP customer interested in receiving events.

Channel is a first-class Eventarc resource that is created and managed by the subscriber in their GCP project. A Channel represents a subscriber's intent to receive events from an event provider. A Channel is associated with exactly one event provider.

ChannelConnection is a first-class Eventarc resource that is created and managed by the partner in their GCP project. A ChannelConnection represents a connection between a partner and a subscriber's Channel. A ChannelConnection has a one-to-one mapping with a Channel.

Publisher allows an event provider to publish events to Eventarc.

Constructor Details

#initialize {|config| ... } ⇒ Client

Create a new Publisher client object.

Examples:


# Create a client using the default configuration
client = ::Google::Cloud::Eventarc::Publishing::V1::Publisher::Client.new

# Create a client using a custom configuration
client = ::Google::Cloud::Eventarc::Publishing::V1::Publisher::Client.new do |config|
  config.timeout = 10.0
end

Yields:

  • (config) —

    Configure the Publisher client.

::Google::Cloud::Eventarc::Publishing::V1::Publisher::Client.configure do |config|
  config.timeout = 10.0
end

Yields:

  • (config) —

    Configure the Client client.

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.

Publish events to a message bus.

Examples:

Basic example

require "google/cloud/eventarc/publishing/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Eventarc::Publishing::V1::Publisher::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Eventarc::Publishing::V1::PublishRequest.new

# Call the publish method.
result = client.publish request

# The returned object is of type Google::Cloud::Eventarc::Publishing::V1::PublishResponse.
p result

Overloads:

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.
