Detailed Description

template<class CachedType>
class ArThreadLocalScopedCache< CachedType >

Utility class for custom resolver implementations.

This class wraps up a common pattern for implementing thread-local scoped caches for ArResolver::BeginCacheScope and ArResolver::EndCacheScope.

class MyResolver : public ArResolver {
    using ResolveCache = ArThreadLocalScopedCache<...>;
    ResolveCache _cache;
    
    void BeginCacheScope(VtValue* data) { _cache.BeginCacheScope(data); }
    void EndCacheScope(VtValue* data) { _cache.EndCacheScope(data); }
    void Resolve(...) {
        // If caching is active in this thread, retrieve the current
        // cache and use it to lookup/store values.
        if (ResolveCache::CachePtr cache = _cache.GetCurrentCache()) {
            // ...
        }
        // Otherwise, caching is not active
        // ...
   }
};
