Variables

Protected

Name Type Remarks Include Path Unreal Specifiers
BaseMeshMemoryUsedMB double Current memory used by the cache to store full merged base meshes. MeshPartitionModifierGraphCache.h  
BaseViewCacheData TMap< FGuid, TSharedPtr< FBaseGroupViewCacheData > > Map of base groups to that group's cache data. MeshPartitionModifierGraphCache.h  
BaseViewCacheDataMutex FMutex Locks the BaseViewCacheData and LRUModifier data. MeshPartitionModifierGraphCache.h  
LayersToCacheMutex FRWLock Mutex to lock access to the list of layers to cache. MeshPartitionModifierGraphCache.h  
LeastRecentlyUsedModifiers TLruCache< FSoftObjectPath, TPair< FBaseGroupGuid, double > > LruCache which stores the most recently used modifiers so we can evict modifiers which have not been used across all base sections recently. MeshPartitionModifierGraphCache.h  
MergedBaseCache TLruCache< FGuid, FMergedBaseCacheEntry >   MeshPartitionModifierGraphCache.h  
MergedBaseCacheMutex FRWLock Mutex to lock access to the LruCache MeshPartitionModifierGraphCache.h  

Functions

Public

Name Remarks Include Path Unreal Specifiers

void CacheBaseGroupViewCacheData ( const FGuid& InBaseGroupCacheKey,
FBaseGroupViewCacheData&& InBaseGroupViewCacheData
)

 Writes the InBaseGroupCacheData into the persistent cache, moving the data out of the input parameter. MeshPartitionModifierGraphCache.h  

void CacheMergedBaseMesh ( const FGuid& InCacheKey,
const FMeshData& InMesh
)

 Stores a new mesh result in the cache with the corresponding cache key. MeshPartitionModifierGraphCache.h  

void Clear()

 Clears all cache entries and resets the cache. MeshPartitionModifierGraphCache.h  

bool CopyBaseGroupViewCacheData ( const FGuid& InBaseGroupKey,
TConstArrayView< FSoftObjectPath > InModifierPaths,
FBaseGroupViewCacheData& OutBaseGroupViewCacheData
)

 Copies all cache entries for the passed set of modifier guids in a given base set into the output cache data. MeshPartitionModifierGraphCache.h  

bool GetCachedMergedBaseMesh ( const FGuid& InCacheKey,
FMeshData& OutCachedMesh
)

 Retrieves a copy of an entry of the cache, if it exists. MeshPartitionModifierGraphCache.h  

double GetMergedBaseCacheMemoryUsageMB()

 Returns the current memory usage of the view cache in MB. MeshPartitionModifierGraphCache.h  

double GetTotalMemoryUsageMB()

 Returns the current memory usage of the cache in MB. MeshPartitionModifierGraphCache.h  

double GetViewCacheMemoryUsageMB()

 Returns the current memory usage of the view cache in MB. MeshPartitionModifierGraphCache.h
