Values
| Name | Description |
|---|---|
| Original | The original version. |
| CustomFields | Support for custom fields. |
| StartStoringVersion | Started storing the version number. |
| DataFileRenames | Made after data files where renamed to include the hash value, these chunks now go to ChunksV2. |
| StoresIfChunkOrFileData | Manifest stores whether build was constructed with chunk or file data. |
| StoresDataGroupNumbers | Manifest stores group number for each chunk/file data for reference so that external readers don't need to know how to calculate them. |
| ChunkCompressionSupport | Added support for chunk compression, these chunks now go to ChunksV3. NB: Not File Data Compression yet. |
| StoresPrerequisitesInfo | Manifest stores product prerequisites info. |
| StoresChunkFileSizes | Manifest stores chunk download sizes. |
| StoredAsCompressedUClass | Manifest can optionally be stored using UObject serialization and compressed. |
| UNUSED_0 | These two features were removed and never used. |
| UNUSED_1 | |
| StoresChunkDataShaHashes | Manifest stores chunk data SHA1 hash to use in place of data compare, for faster generation. |
| StoresPrerequisiteIds | Manifest stores Prerequisite Ids. |
| StoredAsBinaryData | The first minimal binary format was added. UObject classes will no longer be saved out when binary selected. |
| VariableSizeChunksWithoutWindowSizeChunkInfo | Temporary level where manifest can reference chunks with dynamic window size, but did not serialize them. Chunks from here onwards are stored in ChunksV4. |
| VariableSizeChunks | Manifest can reference chunks with dynamic window size, and also serializes them. |
| UsesRuntimeGeneratedBuildId | Manifest uses a build id generated from its metadata. |
| UsesBuildTimeGeneratedBuildId | Manifest uses a build id generated unique at build time, and stored in manifest. |
| LatestPlusOne | !! Always after the latest version entry, signifies the latest version plus 1 to allow the following Latest alias. |
| Latest | An alias for the actual latest version value. |
| LatestNoChunks | An alias to provide the latest version of a manifest supported by file data (nochunks). |
| LatestJson | An alias to provide the latest version of a manifest supported by a json serialized format. |
| FirstOptimisedDelta | An alias to provide the first available version of optimised delta manifest saving. |
| StoresUniqueBuildId | More aliases, but this time for values that have been renamed. |
| BrokenJsonVersion | JSON manifests were stored with a version of 255 during a certain CL range due to a bug. |
| Invalid | This is for UObject default, so that we always serialize it. |
Remarks
An enum type to describe supported features of a certain manifest.
