Subject: [PATCH] Use ConcurrentHashMap in JsonList
|
|
|
|
This is specifically aimed at fixing #471
|
|
|
|
Using a ConcurrentHashMap because thread safety
|
|
The performance benefit of Map over ConcurrentMap is negligabe at best in this scenaio, as most operations will be get and not add or remove
|
|
Even without considering the use-case the benefits are still negligable
|
|
|
|
Original ideas for the system included an expiration policy and/or handler
|
|
The simpler solution was to use a computeIfPresent in the get method
|
|
This will simultaneously have an O(1) lookup time and automatically expire any values
|
|
Since the get method (nor other similar methods) don't seem to have a critical need to flush the map to disk at any of these points further processing is simply wasteful
|
|
Meaning the original function expired values unrelated to the current value without actually having any explicit need to
|
|
|
|
The h method was heavily modified to be much more efficient in its processing
|
|
Also instead of being called on every get, it's now called just before a save
|
|
This will eliminate stale values being flushed to disk
|
|
|
|
Modified isEmpty to use the isEmpty() method instead of the slightly confusing size() < 1
|
|
The point of this is readability, but does have a side-benefit of a small microptimization
|
|
|
|
Finally, added a couple obfhelpers for the modified code
