Methods

#all

def all(&block) { |table| ... } -> Enumerator, nil

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
  • (table) — The block for accessing each table instance.
Yield Parameter
  • table (Table) — The table instance object.
Returns
  • (Enumerator, nil) — An enumerator is returned if no block is given, otherwise nil.
Examples

Iterating each table by passing a block:

require "google/cloud/bigtable"

bigtable = Google::Cloud::Bigtable.new

bigtable.tables("my-instance").all do |table|
  puts table.table_id
end

Using the enumerator by not passing a block:

require "google/cloud/bigtable"

bigtable = Google::Cloud::Bigtable.new

all_table_ids = bigtable.tables("my-instance").all.map do |table|
  puts table.table_id
end

#next

def next() -> Table::List

Retrieves the next page of tables.

Returns
Example 
require "google/cloud/bigtable"

bigtable = Google::Cloud::Bigtable.new

tables = bigtable.tables "my-instance"
if tables.next?
  next_tables = tables.next
end

#next?

def next?() -> Boolean

Whether there is a next page of tables.

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

bigtable = Google::Cloud::Bigtable.new

tables = bigtable.tables "my-instance"
if tables.next?
  next_tables = tables.next
end
