Cloud Bigtable API - Class Google::Cloud::Bigtable::ValueRange (v2.8.0)

Reference documentation and code samples for the Cloud Bigtable API class Google::Cloud::Bigtable::ValueRange.

ValueRange

Specifies a contiguous range of string values.

  • from value bound : The value at which to begin the range. If neither field is set, interpreted as an empty string, inclusive.
  • End value bound: The value at which to end the range. If neither field is set, interpreted as an infinite string value, exclusive.

Inherits

  • Object

Example

require "google/cloud/bigtable"

bigtable = Google::Cloud::Bigtable.new
table = bigtable.table "my-instance", "my-table"

# Range that includes all row keys including "value-001" to "value-005" excluding.
table.new_value_range.from("value-001").to("value-005")

# Range that includes all row keys including "value-001" up to inclusive "value-010".
table.new_value_range.from("value-001").to("value-010", inclusive: true)

# Range that includes all row keys including "value-001" up until end of the row keys.
table.new_value_range.from "value-001"

# Range that includes all row keys exclusive "value-001" up until end of the row keys.
table.new_value_range.from "value-001", inclusive: false

# Range with unbounded from and the exclusive end "value-100".
table.new_value_range.to "value-100"

# Range that includes all row keys including from and end row keys "value-001", "value-100".
table.new_value_range.between "value-001", "value-100"

# Range that includes all row keys including "value-001" up until "value-100".
table.new_value_range.of "value-001", "value-100"

Methods

#between

def between(from_value, to_value) -> Google::Cloud::Bigtable::ValueRange

Sets the value range with inclusive lower and upper bounds.

Parameters
  • from_value (String, Integer) — Inclusive from value. Required. If the argument is an Integer, it will be encoded as a 64-bit signed big-endian integer.
  • to_value (String, Integer) — Inclusive to value. Required. If the argument is an Integer, it will be encoded as a 64-bit signed big-endian integer.
Returns
Example 
require "google/cloud/bigtable"

bigtable = Google::Cloud::Bigtable.new
table = bigtable.table "my-instance", "my-table"

range = table.new_value_range.between "value-001", "value-010"

#from

def from(value, inclusive: true) -> Google::Cloud::Bigtable::ValueRange

Sets the row range with the lower bound.

Parameters
  • value (String, Integer) — The value. Required. If the argument is an Integer, it will be encoded as a 64-bit signed big-endian integer.
  • inclusive (Boolean) (defaults to: true) — Whether the value is an inclusive or exclusive lower bound. Default is true, an inclusive lower bound.
Returns
Examples

Inclusive lower bound.

require "google/cloud/bigtable"

bigtable = Google::Cloud::Bigtable.new
table = bigtable.table "my-instance", "my-table"

range = table.new_value_range.from "value-001"

Exclusive lower bound.

require "google/cloud/bigtable"

bigtable = Google::Cloud::Bigtable.new
table = bigtable.table "my-instance", "my-table"

range = table.new_value_range.from "value-001", inclusive: false

#of

def of(from_value, to_value) -> Google::Cloud::Bigtable::ValueRange

Set value range with an inclusive lower bound and an exclusive upper bound.

Parameters
  • from_value (String, Integer) — Inclusive from value. Required. If the argument is an Integer, it will be encoded as a 64-bit signed big-endian integer.
  • to_value (String, Integer) — Exclusive to value. Required. If the argument is an Integer, it will be encoded as a 64-bit signed big-endian integer.
Returns
Example 
require "google/cloud/bigtable"

bigtable = Google::Cloud::Bigtable.new
table = bigtable.table "my-instance", "my-table"

range = table.new_value_range.of "value-001", "value-010"

#to

def to(value, inclusive: false) -> Google::Cloud::Bigtable::ValueRange

Sets the value range with upper bound.

Parameters
  • value (String, Integer) — value. Required. If the argument is an Integer, it will be encoded as a 64-bit signed big-endian integer.
  • inclusive (Boolean) (defaults to: false) — Whether the value is an inclusive or exclusive lower bound. Default is false, an exclusive lower bound.
Returns
Examples

Inclusive upper bound.

require "google/cloud/bigtable"

bigtable = Google::Cloud::Bigtable.new
table = bigtable.table "my-instance", "my-table"

range = table.new_value_range.to "value-010", inclusive: true

Exclusive upper bound.

require "google/cloud/bigtable"

bigtable = Google::Cloud::Bigtable.new
table = bigtable.table "my-instance", "my-table"

range = table.new_value_range.to "value-010"
