Class Method Details

.from_bson(buffer, **options) ⇒ Integer | BSON::Int64

Deserialize an Integer from BSON.

Parameters:

  • buffer (ByteBuffer) —

    The byte buffer.

  • options (Hash) —

    a customizable set of options

Options Hash (**options):

  • :mode (nil | :bson) —

    Decoding mode to use.

Returns:

Instance Method Details

#==(other) ⇒ true, false Also known as: eql?, ===

Check equality of the int64 with another object.

Parameters:

  • other (Object) —

    The object to check against.

Returns:

  • (true, false) —

    If the objects are equal.

Since:

  • 4.4.0

def ==(other)
  return false unless other.is_a?(Int64)
  value == other.value
end

#as_extended_json(**options) ⇒ Hash | Integer

Converts this object to a representation directly serializable to Extended JSON (github.com/mongodb/specifications/blob/master/source/extended-json.rst).

This method returns the integer value if relaxed representation is requested, otherwise a $numberLong hash.

Parameters:

  • opts (Hash) —

    a customizable set of options

Returns:

  • (Hash | Integer) —

    The extended json representation.

Since:

  • 2.0.0

    {'$numberLong' => value.to_s}
  end
end

#as_json(**options) ⇒ Integer

Return a string representation of the Int64 for use in application-level JSON serialization. This method is intentionally different from #as_extended_json.

Examples:

Get the Int64 as a JSON-serializable object.

int64.as_json

Returns:

  • (Integer) —

    The Int64 as an Integer.

Since:

  • 2.0.0

#to_bson(buffer = ByteBuffer.new) ⇒ BSON::ByteBuffer

Append the integer as encoded BSON to a ByteBuffer.

Examples:

Encoded the integer and append to a ByteBuffer.

int64.to_bson

Returns:

end

#to_bson_key ⇒ String

Convert the integer to a BSON string key.

Examples:

Convert the integer to a BSON key string.

int.to_bson_key

Returns:

  • (String) —

    The string key.
