module Mongo::Protocol::Serializers::Sections
MongoDB wire protocol serialization strategy for a Section of OP_MSG.
Serializes and de-serializes a list of Sections
.
@since 2.5.0
Public Class Methods
Deserializes a section of an OP_MSG from the IO stream.
@param [ BSON::ByteBuffer ] buffer Buffer containing the sections.
@return [ Array<BSON::Document> ] Deserialized sections.
@since 2.5.0
# File lib/mongo/protocol/serializers.rb, line 205 def self.deserialize(buffer) end_length = (@flag_bits & Msg::FLAGS.index(:checksum_present)) == 1 ? 32 : 0 sections = [] until buffer.length == end_length case byte = buffer.get_byte when PayloadZero::TYPE_BYTE sections << PayloadZero.deserialize(buffer) when PayloadOne::TYPE_BYTE sections += PayloadOne.deserialize(buffer) else raise Error::UnknownPayloadType.new(byte) end end sections end
Serializes the sections of an OP_MSG, payload type 0 or 1.
@param [ BSON::ByteBuffer ] buffer Buffer to receive the serialized Sections
. @param [ Array<Hash, BSON::Document> ] value The sections to be serialized. @param [ Fixnum ] max_bson_size The max bson size of documents in the sections. @param [ true, false ] validating_keys Whether to validate document keys.
@return [ BSON::ByteBuffer ] Buffer with serialized value.

Whether there can be a size limit on this type after serialization.
@return [ true ] Documents can be size limited upon serialization.
