Detailed Description

template<typename T>
class libMesh::Threads::atomic< T >

Defines atomic operations which can only be executed on a single thread at a time. This is used in reference counting, for example, to allow count++/count-- to work.

Defines atomic operations which can only be executed on a single thread at a time.
