run

boolean run(Socket socket,
 Set<IOCondition> condition,
 @Nullable MemorySegment data)

condition - the current condition at the source fired.

data - data passed in by the user.

Returns:

it should return false if the source should be removed.

upcall

default int upcall(MemorySegment socket,
 int condition,
 MemorySegment data)
