Methods
#all
def all(&block) { |job| ... } -> Enumerator
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.
- (job) — The block for accessing each database job.
- job (Google::Cloud::Spanner::Database::Job) — The database job object.
- (Enumerator)
Iterating each database job by passing a block:
require "google/cloud/spanner" spanner = Google::Cloud::Spanner.new instance = spanner.instance "my-instance" jobs = instance.database_operations jobs.all do |job| puts job.database.database_id end
Using the enumerator by not passing a block:
require "google/cloud/spanner" spanner = Google::Cloud::Spanner.new instance = spanner.instance "my-instance" jobs = instance.database_operations all_database_ids = jobs.all.map do |job| job.database.database_id end
#next
def next() -> Google::Cloud::Spanner::Database::Job::List
Retrieve the next page of database jobs.
require "google/cloud/spanner" spanner = Google::Cloud::Spanner.new instance = spanner.instance "my-instance" jobs = instance.database_operations if jobs.next? next_jobs = jobs.next end
#next?
def next?() -> Boolean
Whether there is a next page of database jobs.
- (Boolean)
require "google/cloud/spanner" spanner = Google::Cloud::Spanner.new instance = spanner.instance "my-instance" jobs = instance.database_operations if jobs.next? next_jobs = jobs.next end
