Detailed Description

SpinLock.

Member Enumeration Documentation

◆ eMode

enum class Arcane::SpinLock::eMode : uint8_t

strong

Spinlock mode. The default is 'Auto'.

Enumerator

Auto

Automatic choice.

If Concurrency::getThreadImplementation()->isMultiThread() is true, then the mode is SpinAndMutex. Otherwise, the mode is None.

FullSpin

Always uses a spinlock.

This type is faster if there is very little contention, but performance is very poor otherwise.

SpinAndMutex

SpinLock then mutex.

Performs a spinlock then yields (std::this_thread::yield()) if it takes too long. This mode is only available if C++20 is used. Otherwise, it is equivalent to FullSpin.
