ConcurrentHashMap update for multiple entries
have a situation where in ConcurrentHashMap I store some properties like ip address and port or penalty and code – 2 or more entries connected to each other.
Now I want to update these 2 entries automatically to avoid reading incorrect pairs.
So now I’m thinking about it and don’t know the easy solution.
I can wrap the get/put method with the ReadWriteLock block, but it doesn’t feel right:) I didn’t use ConcurrentHashMap to write extra locks.
Another option is to combine these properties into one. Now I’m leaning towards that option.
The other option is to have a version in the value object, but I need to check it every time and I don’t want to do that 🙂
Are there other solutions to this problem?
You cannot automatically update multiple entries. You have two options:
Use a simple
HashMapwith external synchronization.
Use different types for
Mapvalues, which must be considered together for items.
