Detailed Description

Interface of a service implementing thread support.

This service uses a reference counter and must be destroyed if there are no more references to it. It should therefore generally not be destroyed explicitly.

◆ isMultiThread()

virtual bool Arcane::IThreadImplementation::isMultiThread ( ) const

inlinevirtual

True if the implementation supports multiple threads.

In single-thread mode, only one thread executes. Therefore, there is no need to create synchronization management classes such as Mutexes or SpinLocks.

Reimplemented in Arcane::NullThreadImplementation.
