Cloud PubSub Client - Class Schema (2.16.0)

Reference documentation and code samples for the Cloud PubSub Client class Schema.

Represents a Pub/Sub Schema resource.

Schema Support for Cloud Pub/Sub allows you to register schemas in common formats as standalone versioned resources, associates schemas with Pub/Sub topics, validates message structure on-publish, and provides APIs parameterized on your entity types.

Example:

use Google\Cloud\PubSub\PubSubClient; $client = new PubSubClient(['projectId' => 'my-project']); $schema = $client->schema('my-schema'); 

Get the schema resource name.

Example:

$name = $schema->name(); 

Delete the schema.

Example:

$schema->delete(); 

Get schema information.

Since this method will throw an exception if the schema is not found, you may find that Schema::exists() is a better fit for a true/false check.

This method will use the previously cached result, if available. To force a refresh from the API, use Schema::reload().

Example:

$info = $schema->info(); echo $info['name']; // projects/my-awesome-project/schemas/my-schema 

Get schema information from the API.

Since this method will throw an exception if the schema is not found, you may find that Schema::exists() is a better fit for a true/false check.

This method will retrieve a new result from the API. To use a previously cached result, if one exists, use Schema::info().

Example:

$info = $schema->reload(); echo $info['name']; // projects/my-awesome-project/schemas/my-schema 

Check if a schema exists.

Example:

if ($schema->exists()) { echo 'Schema exists'; }
