Module: Mongo::Protocol::Serializers::Int32 Private

Defined in:

lib/mongo/protocol/serializers.rb

Overview

This module is part of a private API. You should avoid using this module if possible, as it may be removed or be changed in the future.

MongoDB wire protocol serialization strategy for 32-bit integers.

Serializes and de-serializes one 32-bit integer.

Class Method Summary

• .deserialize(buffer, options = {}) ⇒ Fixnum private

  Deserializes a 32-bit Fixnum from the IO stream.

• .serialize(buffer, value, validating_keys = nil) ⇒ String private

  Serializes a number to a 32-bit integer.

Class Method Details

.deserialize(buffer, options = {}) ⇒ Fixnum

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Deserializes a 32-bit Fixnum from the IO stream

Parameters:

• buffer (String) —

  Buffer containing the 32-bit integer

• options (Hash) (defaults to: {}) —

  This method currently accepts no options.

Returns:

• (Fixnum) —

  Deserialized Int32

def self.deserialize(buffer, options = {})
  buffer.get_int32
end

.serialize(buffer, value, validating_keys = nil) ⇒ String

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Serializes a number to a 32-bit integer

Parameters:

• buffer (String) —

  Buffer to receive the serialized Int32.

• value (Integer | BSON::Int32) —

  32-bit integer to be serialized.

Returns:

• (String) —

  Buffer with serialized value.

def self.serialize(buffer, value, validating_keys = nil)
  if value.is_a?(BSON::Int32)
    if value.respond_to?(:value)
      # bson-ruby >= 4.6.0
      value = value.value
    else
      value = value.instance_variable_get('@integer')
    end
  end
  buffer.put_int32(value)
end
