Subject: [PATCH] Folia scheduler and owned region API
|
|
|
|
Pulling Folia API to Paper is primarily intended for plugins
|
|
that want to target both Paper and Folia without unnecessary
|
|
compatibility layers.
|
|
|
|
Add both a location based scheduler, an entity based scheduler,
|
|
and a global region scheduler.
|
|
|
|
Owned region API may be useful for plugins which want to perform
|
|
operations over large areas outside of the buffer zone provided
|
|
by the regionaliser, as it is not guaranteed that anything
|
|
outside of the buffer zone is owned. Then, the plugins may use
|
|
the schedulers depending on the result of the ownership check.

|

+ * The scheduler also allows a task to provide a callback, the "retired" callback, that will be invoked
|
|
+ * if the entity is removed before a task that was scheduled could be executed. The scheduler is also
|
|
+ * completely thread-safe, allowing tasks to be scheduled from any thread context. The scheduler also indicates
|
|
+ * properly whether a task was scheduled successfully (i.e scheduler not retired), thus the code scheduling any task
|
|
+ * knows whether the given callbacks will be invoked eventually or not - which may be critical for off-thread
