Struct BlobAssetStore

Purpose of this class is to provide a consistent cache of BlobAsset object in order to avoid rebuilding them when it is not necessary

Namespace: Unity.Entities

Assembly: Unity.Entities.Hybrid.dll

Syntax

public struct BlobAssetStore

Remarks

Right now the lifetime scope of this cache is bound to the LiveConversionDiffGenerator's one and it is scoped by SubScene. In other words the cache is created when we enter edit mode for a given SubScene and it is released when we close edit mode. And instance of this cache is exposed in Unity.Entities.GameObjectConversionSettings to allow users to query and avoid rebuilding assets. During conversion process the user must rely on the BlobAssetComputationContext<TS, TB> to associate the BlobAsset with their corresponding Authoring UnityObject and to determine which ones are to compute. Thread-safety: nothing is thread-safe, we assume this class is consumed through the main-thread only. Calling Dispose on an instance will reset the content and dispose all BlobAssetReference object stored.

Constructors

Name	Description
BlobAssetStore(int)	Initializes and returns an instance of BlobAssetStore.

Properties

Name	Description
BlobAssetCount	Returns the number of BlobAssetReferences added to the store.
IsCreated	Checks if the BlobAssetStoreInternal has been created

Methods

Name	Description
Contains<T>(Hash128)	Check if the Store contains a BlobAsset of a given type and hash
Dispose()	Calling dispose will reset the cache content and release all the BlobAssetReference that were stored
ResetCache(bool)	Call this method to clear the whole content of the Cache
TryAdd<T>(ref BlobAssetReference<T>)	Add a BlobAssetReference with the default hash key based on the BlobAsset contents itself. If the contents of the generated blob asset is the same as a previously inserted blob asset, then the passed blobAsset will be disposed and the reference to the blob asset will be replaced with the previously added blob asset
TryAdd<T>(ref BlobAssetReference<T>, out Hash128)	Add a BlobAssetReference with the default hash key based on the BlobAsset contents itself. If the contents of the generated blob asset is the same as a previously inserted blob asset, then the passed blobAsset will be disposed and the reference to the blob asset will be replaced with the previously added blob asset
TryAdd<T>(Hash128, ref BlobAssetReference<T>)	Add a BlobAssetReference with a custom hash key
TryGet<T>(Hash128, out BlobAssetReference<T>)	Try to access to a BlobAssetReference from its key
TryRemove<T>(Hash128, bool)	Obsolete. BlobAssetStore uses garbage collection and doesn't allow removing references anymore.
