Inherits

  • Object

Example

require "google/cloud/spanner" spanner = Google::Cloud::Spanner.new job = spanner.create_database "my-instance",  "my-new-database" job.done? #=> false job.reload! # API call job.done? #=> true if job.error?  status = job.error else  database = job.database end

Methods

#database

def database() -> Google::Cloud::Spanner::Database, nil

The database that is the object of the operation.

Returns
Example 
require "google/cloud/spanner" spanner = Google::Cloud::Spanner.new job = spanner.create_database "my-instance",  "my-new-database" job.done? #=> false job.reload! job.done? #=> true database = job.database

#done?

def done?() -> boolean

Checks if the processing of the database operation is complete.

Returns
  • (boolean) — true when complete, false otherwise.
Example 
require "google/cloud/spanner" spanner = Google::Cloud::Spanner.new job = spanner.create_database "my-instance",  "my-new-database" job.done? #=> false

#error

def error() -> Google::Cloud::Spanner::Status, nil

The status if the operation associated with this job produced an error.

Returns
Example 
require "google/cloud/spanner" spanner = Google::Cloud::Spanner.new job = spanner.create_database "my-instance",  "my-new-database" job.error? # true error = job.error

#error?

def error?() -> boolean

Checks if the processing of the database operation has errored.

Returns
  • (boolean) — true when errored, false otherwise.
Example 
require "google/cloud/spanner" spanner = Google::Cloud::Spanner.new job = spanner.create_database "my-instance",  "my-new-database" job.error? #=> false

#refresh!

def refresh!() -> Google::Cloud::Spanner::Database::Job
Alias Of: #reload!

Reloads the job with current data from the long-running, asynchronous processing of a database operation.

Returns
Example 
require "google/cloud/spanner" spanner = Google::Cloud::Spanner.new job = spanner.create_database "my-instance",  "my-new-database" job.done? #=> false job.reload! # API call job.done? #=> true

#reload!

def reload!() -> Google::Cloud::Spanner::Database::Job
Aliases

Reloads the job with current data from the long-running, asynchronous processing of a database operation.

Returns
Example 
require "google/cloud/spanner" spanner = Google::Cloud::Spanner.new job = spanner.create_database "my-instance",  "my-new-database" job.done? #=> false job.reload! # API call job.done? #=> true

#wait_until_done!

def wait_until_done!()

Reloads the job until the operation is complete. The delay between reloads will incrementally increase.

Example 
require "google/cloud/spanner" spanner = Google::Cloud::Spanner.new job = spanner.create_database "my-instance",  "my-new-database" job.done? #=> false job.wait_until_done! job.done? #=> true
