PHP Google\Cloud\PubSub Topic::exists Beispiele

exists() public method

Service errors will NOT bubble up from this method. It will always return a boolean value. If you want to check for errors, use {@see \Google\Cloud\PubSub\Topic::info()}. Example: if ($topic->exists()) { echo 'Topic exists'; }

public exists ( array $options = [] ) : boolean
$options	array	[optional] Configuration Options
return	boolean
