Channel class
A representation of the Channel resource. A Channel is a resource on which event providers publish their events. The published events are delivered through the transport associated with the channel. Note that a channel is associated with exactly one event provider.

Properties
- activationToken ↔ String
-
Output only. The activation token for the channel. The token must be used
by the provider to register the channel for publishing.
getter/setter pair
- createTime ↔ Timestamp
-
Output only. The creation time.
getter/setter pair
- cryptoKeyName ↔ String
-
Resource name of a KMS crypto key (managed by the user) used to
encrypt/decrypt their event data.
getter/setter pair
- eventPlugin → EventPlugin?
-
Subclasses can override this getter to be notified of changes
to protobuf fields.
no setterinherited
- hashCode → int
-
Calculates a hash code based on the contents of the protobuf.
no setterinherited
- info_ → BuilderInfo
-
no setteroverride
- isFrozen → bool
-
Returns
trueif this message is marked read-only. Otherwisefalse.no setterinherited - name ↔ String
-
Required. The resource name of the channel. Must be unique within the
location on the project and must be in
projects/{project}/locations/{location}/channels/{channel_id}format.getter/setter pair - provider ↔ String
-
The name of the event provider (e.g. Eventarc SaaS partner) associated
with the channel. This provider will be granted permissions to publish
events to the channel. Format:
projects/{project}/locations/{location}/providers/{provider_id}.getter/setter pair - pubsubTopic ↔ String
-
Output only. The name of the Pub/Sub topic created and managed by
Eventarc system as a transport for the event delivery. Format:
projects/{project}/topics/{topic_id}.getter/setter pair - runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- state ↔ Channel_State
-
Output only. The state of a Channel.
getter/setter pair
- uid ↔ String
-
Output only. Server assigned unique identifier for the channel. The value
is a UUID4 string and guaranteed to remain unchanged until the resource is
deleted.
getter/setter pair
- unknownFields → UnknownFieldSet
-
no setterinherited
- updateTime ↔ Timestamp
-
Output only. The last-modified time.
