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
* // ...
* }
* };
