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.

Yields
  • (job) — The block for accessing each database job.
Yield Parameter
Returns
  • (Enumerator)
Examples

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.

Returns
Example 
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.

Returns
  • (Boolean)
Example 
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
