Class TypeManager
The TypeManager registers all Components and Systems available at runtime. Information about components and systems can be retrieved at runtime via static methods on TypeManager. The Initialize() method must be invoked before the TypeManager can be used.
Namespace: Unity.Entities

Syntax
public static class TypeManagerFields
| Name | Description |
|---|---|
| BakingOnlyTypeFlag | Bitflag set for component types decorated with the BakingTypeAttribute attribute. |
| BufferComponentTypeFlag | Bitflag set for component types inheriting from IBufferElementData. |
| ChunkComponentTypeFlag | Bitflag set for component types converted into Chunk Components. |
| CleanupBufferComponentTypeFlag | Bitflag set for component types inheriting from ICleanupBufferElementData. |
| CleanupComponentTypeFlag | Bitflag set for component types inheriting from ISystemStateComponentData. |
| CleanupSharedComponentTypeFlag | Bitflag set for component types inheriting from ICleanupSharedComponentData. |
| ClearFlagsMask | Bit mask to clear all flag bits from a TypeIndex /> |
| DefaultBufferCapacityNumerator | BufferCapacity is by default calculated as DefaultBufferCapacityNumerator / sizeof(BufferElementDataType) thus for a 1 byte component, the maximum number of elements possible to be stored in chunk memory before the buffer is allocated separately from chunk data, is DefaultBufferCapacityNumerator elements. For a 2 byte sized component, (DefaultBufferCapacityNumerator / 2) elements can be stored, etc... |

| HasNativeContainerFlag | Bitflag set for component types with NativeContainer data NativeContainerAttribute. |
| HasNoEntityReferencesFlag | Bitflag set for component types that do not contain an Entity member. Entity members found in nested member types will cause this bitflag to not be set. |
| IEquatableTypeFlag | Bitflag set for component types inheriting from IEquatable<T>. |
| IRefCountedComponentFlag | Bitflag set for component types inheriting from IRefCounted. |
| IsNotChunkSerializableTypeFlag | Bitflag set if a component is not appropriate to be included in chunk serialization. |
| ManagedComponentTypeFlag | Bitflag set for component types requiring managed storage due to being a class type and/or containing managed references. |
| ManagedSharedComponentTypeFlag | Bitflag set for component types inheriting from ISharedComponentData and requiring managed storage due to containing managed references. |
| MaximumChunkCapacity | Maximum number of Entity instances stored in a given Chunk/> |
| MaximumSupportedAlignment | Maximum platform alignment supported when aligning component data in a Chunk/> |
| MaximumTypesCount | Maximum number of unique component types supported by the TypeManager/> |
| ObjectOffset | Offset into managed objects to read instance data |
| SharedComponentTypeFlag | Bitflag set for component types inheriting from ISharedComponentData. |
| SystemStateSharedComponentTypeFlag | Obsolete. Use CleanupSharedComponentTypeFlaginstead. |
| SystemStateTypeFlag | Obsolete. Use CleanupComponentTypeFlag instead. |
| TemporaryBakingTypeFlag | Bitflag set for component types decorated with the TemporaryBakingTypeAttribute attribute. |
| ZeroSizeInChunkTypeFlag | Bitflag set for component types which allocate 0 bytes in Chunk storage |
