Overview

MongoDB wire protocol serialization strategy for 32-bit integers.

Serializes and de-serializes one 32-bit integer.

Class Method Summary

Class Method Details

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

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
