Detailed Description

template<class T>
class Urho3D::ThreadSafeCache< T >

Thread-safe cache that holds an object. It's safe to:

• Invalidate cached object from multiple threads;
• Restore cached object from multiple threads, as long as all threads assign the same value. It's unsafe to both invalidate and restore cached object from multiple threads simultaneously. If different threads assign different values on Restore, cache will keep first provided value.
