K2Daemon/ClientCache.h - header for client cache module
|
||
|
|
|
||
|
|
This module encapsulates containers for efficiently storing
|
||
|
|
and accessing client connection and retry state data. Its
|
||
|
|
public functions operate on that data.
|
||
|
|
|
||
|
|
It has grown organically to a size that probably requires
|
||
|
|
refactoring. Potential sub-modules include: UDP protocol,
|
||
|
|
client cache, retry cache, high-level message handlers.
