Google Cloud Eventarc Publishing V1 Client - Class PublisherClient (1.1.1)

Reference documentation and code samples for the Google Cloud Eventarc Publishing V1 Client class PublisherClient.

Service Description: 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.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods.

Namespace

Google \ Cloud \ Eventarc \ Publishing \ V1 \ Client

Methods

__construct

Constructor.

Parameters
Name	Description
`options`	`array` Optional. Options for configuring the service API wrapper.
`↳ apiEndpoint`	`string` The address of the API remote host. May optionally include the port, formatted as "
`↳ credentials`	`string\|array\|FetchAuthTokenInterface\|CredentialsWrapper` The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage: In addition, this option can also accept a pre-constructed Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored.
`↳ credentialsConfig`	`array` Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see Google\ApiCore\CredentialsWrapper::build() .
`↳ disableRetries`	`bool` Determines whether or not retries defined by the client configuration should be disabled. Defaults to `false`.
`↳ clientConfig`	`string\|array` Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder.
`↳ transport`	`string\|TransportInterface` The transport used for executing network requests. May be either the string `rest` or `grpc`. Defaults to `grpc` if gRPC support is detected on the system. Advanced usage: Additionally, it is possible to pass in an already instantiated Google\ApiCore\Transport\TransportInterface object. Note that when this object is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored.
`↳ transportConfig`	`array` Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport. For example: $transportConfig = [ 'grpc' => [...], 'rest' => [...], ]; See the Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() methods for the supported options.
`↳ clientCertSource`	`callable` A callable which returns the client cert as a string. This can be used to provide a certificate and private key to the transport layer for mTLS.
