class Google::Cloud::Bigtable::AppProfile::List
AppProfile::List
is a special-case array with additional values.
Attributes
@private The gRPC page enumerable object.
@private The gRPC Service
object.
Public Class Methods
@private New Snapshot::List from a Gapic::PagedEnumerable<Google::Cloud::Bigtable::Admin::V2::AppProfile> object.
@param grpc [Gapic::PagedEnumerable<Google::Cloud::Bigtable::Admin::V2::AppProfile> ] @param service [Google::Cloud::Bigtable::Service] @return [Array<Google::Cloud::Bigtable::AppProfile>]
# File lib/google/cloud/bigtable/app_profile/list.rb, line 142 def self.from_grpc grpc, service app_profiles = List.new( Array(grpc.response.app_profiles).map do |app_profile| AppProfile.from_grpc app_profile, service end ) app_profiles.grpc = grpc app_profiles.service = service app_profiles end
@private Creates a new AppProfile::List
with an array of app profiles.

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.
@yield [app_profile] The block for accessing each app profile. @yieldparam [AppProfile] app_profile The app profile object.
@return [Enumerator,nil] An enumerator is returned if no block is given, otherwise `nil`.
@example Iterating each app profile by passing a block:
require "google/cloud/bigtable" bigtable = Google::Cloud::Bigtable.new instance = bigtable.instance "my-instance" app_profiles = instance.app_profiles instance.app_profiles.all do |app_profile| puts app_profile.name end
@example Using the enumerator by not passing a block:
require "google/cloud/bigtable" bigtable = Google::Cloud::Bigtable.new instance = bigtable.instance "my-instance" all_app_profile_ids = instance.app_profiles.all.map(&:name)
# File lib/google/cloud/bigtable/app_profile/list.rb, line 123 def all &block return enum_for :all unless block_given? results = self loop do results.each(&block) break unless next? grpc.next_page results = self.class.from_grpc grpc, service end end
Retrieves the next page of app profiles.
@return [AppProfile::List] The list of app profiles.
@example
require "google/cloud/bigtable" bigtable = Google::Cloud::Bigtable.new instance = bigtable.instance "my-instance" app_profiles = instance.app_profiles if app_profiles.next? next_app_profiles = app_profiles.next end
# File lib/google/cloud/bigtable/app_profile/list.rb, line 78 def next ensure_grpc! return nil unless next? grpc.next_page self.class.from_grpc grpc, service end
Whether there is a next page of app profiles.
@return [Boolean]
@example
require "google/cloud/bigtable" bigtable = Google::Cloud::Bigtable.new instance = bigtable.instance "my-instance" app_profiles = instance.app_profiles if app_profiles.next? next_app_profiles = app_profiles.next end
# File lib/google/cloud/bigtable/app_profile/list.rb, line 57 def next? grpc.next_page? end
