Methods

#all

def all(request_limit: nil, &block) { |dataset| ... } -> 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.

Parameter
  • request_limit (Integer) (defaults to: nil) — The upper limit of API requests to make to load all datasets. Default is no limit.
Yields
  • (dataset) — The block for accessing each dataset.
Yield Parameter
  • dataset (Dataset) — The dataset object.
Returns
  • (Enumerator)
Examples

Iterating each result by passing a block:

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new

bigquery.datasets.all do |dataset|
  puts dataset.name
end

Using the enumerator by not passing a block:

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new

all_names = bigquery.datasets.all.map do |dataset|
  dataset.name
end

Limit the number of API calls made:

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new

bigquery.datasets.all(request_limit: 10) do |dataset|
  puts dataset.name
end

#etag

def etag()

A hash of this page of results.

#etag=

def etag=(value)

A hash of this page of results.

#next

def next() -> Dataset::List

Retrieve the next page of datasets.

Returns
Example 
require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new

datasets = bigquery.datasets
if datasets.next?
  next_datasets = datasets.next
end

#next?

def next?() -> Boolean

Whether there is a next page of datasets.

Returns
  • (Boolean)
Example 
require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new

datasets = bigquery.datasets
if datasets.next?
  next_datasets = datasets.next
end

#token

def token()

If not empty, indicates that there are more records that match the request and this value should be passed to continue.

#token=

def token=(value)

If not empty, indicates that there are more records that match the request and this value should be passed to continue.
