• 2.5.0

0x0

TYPE_BYTE =

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

The byte corresponding to this payload type.

Class Method Summary

• .deserialize(buffer) ⇒ Array<BSON::Document> private

  Deserializes a section of payload type 0 of an OP_MSG from the IO stream.

• .serialize(buffer, value, max_bson_size = nil, validating_keys = BSON::Config.validating_keys?) ⇒ BSON::ByteBuffer private

  Serializes a section of an OP_MSG, payload type 0.

Class Method Details

.deserialize(buffer) ⇒ Array<BSON::Document>

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 section of payload type 0 of an OP_MSG from the IO stream.

Parameters:

• buffer (BSON::ByteBuffer) —

  Buffer containing the sections.

Returns:

• (Array<BSON::Document>) —

  Deserialized section.

Since:

• 2.5.0

# File 'lib/mongo/protocol/serializers.rb', line 251

def self.deserialize(buffer)
  BSON::Document.from_bson(buffer)
end

.serialize(buffer, value, max_bson_size = nil, validating_keys = BSON::Config.validating_keys?) ⇒ BSON::ByteBuffer

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 section of an OP_MSG, payload type 0.

Parameters:

• buffer (BSON::ByteBuffer) —

  Buffer to receive the serialized Sections.

• value (BSON::Document, Hash) —

  The object to serialize.

• max_bson_size (Fixnum) (defaults to: nil) —

  The max bson size of documents in the section.

• validating_keys (true, false) (defaults to: BSON::Config.validating_keys?) —

  Whether to validate document keys.

Returns:

• (BSON::ByteBuffer) —

  Buffer with serialized value.

Since:

• 2.5.0

# File 'lib/mongo/protocol/serializers.rb', line 239

def self.serialize(buffer, value, max_bson_size = nil, validating_keys = BSON::Config.validating_keys?)
  buffer.put_byte(TYPE_BYTE)
  Serializers::Document.serialize(buffer, value, max_bson_size, validating_keys)
