c++ struct and container

Question

I am writing a small software which deals with inter-process multicast. For each message, on each process, I have a couple of variables assigned to the message itself:

messageID
senderID
ack1
ack2
ack3
...

I would like to put these elements (which are many) in a container, so that it is later easy to perform operations such as changing the value of ack1 for a given messageID (I should keep trace of which processes in my group notified me that they got the message).

Which is the best container to use in this case?

Thanks

Answer 1

您可以使用地图通过messageID轻松获取结构： http : messageID

Answer 2

You might want to use std::map or boost::unordered_map (soon to be standard) as you can access it by message id.

Answer 3

除了std::map和boost::unordered_map ，如果您打算遍历给定senderID的消息，则可以使用boost::multi_index_container 。
