class Google::Cloud::Bigquery::Routine::List
Routine::List
is a special case Array with additional values.
Attributes
If not empty, indicates that there are more records that match the request and this value should be passed to continue.
Public Class Methods
@private New Routine::List
from a response object.
# File lib/google/cloud/bigquery/routine/list.rb, line 144 def self.from_gapi gapi_list, service, dataset_id = nil, max = nil, filter: nil routines = List.new(Array(gapi_list.routines).map { |gapi| Routine.from_gapi gapi, service }) routines.instance_variable_set :@token, gapi_list.next_page_token routines.instance_variable_set :@service, service routines.instance_variable_set :@dataset_id, dataset_id routines.instance_variable_set :@max, max routines.instance_variable_set :@filter, filter routines end
@private Create a new Routine::List
with an array of routines.

Public Instance Methods
Retrieves remaining results by repeatedly invoking {#next} until {#next?} returns `false`. Calls the given block once for each result, which is passed as the argument to the block.
An Enumerator is returned if no block is given.
This method will make repeated API calls until all remaining results are retrieved. (Unlike `#each`, for example, which merely iterates over the results returned by a single API call.) Use with caution.
@param [Integer] request_limit The upper limit of API requests to
make to load all routines. Default is no limit.
@yield [routine] The block for accessing each routine. @yieldparam [Routine] routine The routine object.
@return [Enumerator]
@example Iterating each result by passing a block:
require "google/cloud/bigquery" bigquery = Google::Cloud::Bigquery.new dataset = bigquery.dataset "my_dataset" dataset.routines.all do |routine| puts routine.routine_id end
@example Using the enumerator by not passing a block:
require "google/cloud/bigquery" bigquery = Google::Cloud::Bigquery.new dataset = bigquery.dataset "my_dataset" all_names = dataset.routines.all.map do |routine| routine.routine_id end
@example Limit the number of API requests made:
require "google/cloud/bigquery" bigquery = Google::Cloud::Bigquery.new dataset = bigquery.dataset "my_dataset" dataset.routines.all(request_limit: 10) do |routine| puts routine.routine_id end
# File lib/google/cloud/bigquery/routine/list.rb, line 127 def all request_limit: nil, &block request_limit = request_limit.to_i if request_limit return enum_for :all, request_limit: request_limit unless block_given? results = self loop do results.each(&block) if request_limit request_limit -= 1 break if request_limit.negative? end break unless results.next? results = results.next end end
Retrieve the next page of routines.
@return [Routine::List]
@example
require "google/cloud/bigquery" bigquery = Google::Cloud::Bigquery.new dataset = bigquery.dataset "my_dataset" routines = dataset.routines if routines.next? next_routines = routines.next end
# File lib/google/cloud/bigquery/routine/list.rb, line 72 def next return nil unless next? ensure_service! gapi = @service.list_routines @dataset_id, token: token, max: @max, filter: @filter self.class.from_gapi gapi, @service, @dataset_id, @max, filter: @filter end
Whether there is a next page of routines.
@return [Boolean]
@example
require "google/cloud/bigquery" bigquery = Google::Cloud::Bigquery.new dataset = bigquery.dataset "my_dataset" routines = dataset.routines if routines.next? next_routines = routines.next end
# File lib/google/cloud/bigquery/routine/list.rb, line 52 def next? !token.nil? end
Protected Instance Methods
Raise an error unless an active service is available.
