Subject: [PATCH] Remove streams from SensorNearest
|
|
|
|
The behavioural nearby sensors are validated every tick on the entities
|
|
that registered the respective sensors and are therefore a good subject
|
|
to performance improvements.
|
|
|
|
More specifically this commit replaces the Stream#filter usage with
|
|
ArrayList#removeIf as the removeIf method on an array list is heavily
|
|
optimized towards a single internal array re-allocation without any
|
|
further overhead on the removeIf call.
|
|
|
|
The only negative of this change is the rather agressive diff these
|
|
patches introduce as the methods are basically being reimplemented
|
|
compared to the previous stream-based implementation.
|
