# TypeManager.TypeInfo > Provides information about component types such as their runtime size, how much space they use in Chunk storage, their TypeManager.TypeInfo.TypeIndex, how many entity references they contain, and more. ## Definition * **Type:** Struct * **Namespace:** [Unity.Entities](/engine/7000.0/script-reference/unity/entities.md) * **Assembly:** UnityEngine.EntitiesModule ```csharp public readonly struct TypeManager.TypeInfo ``` ## Fields | Value | Description | | ------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [AlignmentInBytes](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/alignmentinbytes.md) | The alignment requirement for the component. For buffer types, this is the alignment requirement of the element type. | | [BlobAssetRefOffsetCount](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/blobassetrefoffsetcount.md) | Number of [BlobAssetReference\](/engine/7000.0/script-reference/unity/entities/blobassetreference1.md)s this component can store. | | [BloomFilterMask](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/bloomfiltermask.md) | Bitmask used to accelerate "is type set A a subset of type set B?" queries. | | [BufferCapacity](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/buffercapacity.md) | The maximum number of elements that can be stored in a buffer component instance. | | [Category](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/category.md) | [TypeManager.TypeCategory](/engine/7000.0/script-reference/unity/entities/typemanager/typecategory.md) | | [ElementSize](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/elementsize.md) | The size of an element store in buffer components. For non-buffer component types, this is the same as [TypeManager.TypeInfo.SizeInChunk](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/sizeinchunk.md) | | [EntityOffsetCount](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/entityoffsetcount.md) | Number of [Entity](/engine/7000.0/script-reference/unity/entities/entity.md) references this component can store. | | [MaximumChunkCapacity](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/maximumchunkcapacity.md) | Maximum number of instances of this component allowed to be stored in a Chunk. | | [MemoryOrdering](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/memoryordering.md) | Sort order for component types in Chunk storage. By default this is equivalent to [TypeManager.TypeInfo.StableTypeHash](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/stabletypehash.md). Order is sorted from lowest to highest. | | [SizeInChunk](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/sizeinchunk.md) | The number of bytes used in a Chunk to store an instance of this component. | | [StableTypeHash](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/stabletypehash.md) | Hash used to uniquely identify a component based on its runtime memory footprint. | | [TypeIndex](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/typeindex.md) | [TypeManager.TypeInfo.TypeIndex](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/typeindex.md) | | [TypeSize](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/typesize.md) | Blittable size of the component type. | | [WeakAssetRefOffsetCount](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/weakassetrefoffsetcount.md) | Number of WeakReference\_1s this component can store. | ## Constructors | Constructor | Description | | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------- | | [TypeInfo(System.Int32,Unity.Entities.TypeManager.TypeCategory,System.Int32,System.Int32,System.UInt64,System.UInt64,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean,System.Int32,System.Int32,System.Int32,System.UInt64)](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/ctor.md) | Used internally to construct a TypeInfo. | ## Properties | Property | Description | | ------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [AlignmentInChunkInBytes](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/alignmentinchunkinbytes.md) | Alignment of this type in a chunk. Normally the same as AlignmentInBytes, but that might be less than this value for buffer elements, whereas the buffer itself must be aligned to [TypeManager.MaximumSupportedAlignment](/engine/7000.0/script-reference/unity/entities/typemanager/maximumsupportedalignment.md). | | [BakingOnlyType](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/bakingonlytype.md) | [TypeIndex.IsBakingOnlyType](/engine/7000.0/script-reference/unity/entities/typeindex/isbakingonlytype.md) | | [DebugTypeName](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/debugtypename.md) | Provides a HPC# / Burst compatible name of the component type when building with DEBUG defined. Otherwise the name is empty. | | [EnableableType](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/enableabletype.md) | [TypeIndex.IsEnableable](/engine/7000.0/script-reference/unity/entities/typeindex/isenableable.md) | | [HasBlobAssetRefs](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/hasblobassetrefs.md) | For struct IComponentData, a value of true guarantees that there are [BlobAssetReference\](/engine/7000.0/script-reference/unity/entities/blobassetreference1.md) fields in this component. For class based IComponentData, a value of true means it is possible, but not guaranteed, that there are blob asset references. (Polymorphic [BlobAssetReference\](/engine/7000.0/script-reference/unity/entities/blobassetreference1.md) members can not be proven statically) | | [HasUnityObjectRefs](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/hasunityobjectrefs.md) | Returns whether there are any UnityObjectRefs fields in this component. | | [HasWeakAssetRefs](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/hasweakassetrefs.md) | For struct IComponentData, a value of true guarantees that there are WeakReference\_1 fields in this component. For class based IComponentData, a value of true means it is possible, but not guaranteed, that there are WeakReferences. (Polymorphic WeakReference\_1 members can not be proven statically) | | [IsZeroSized](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/iszerosized.md) | Returns true if the component does not require space in Chunk memory | | [TemporaryBakingType](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/temporarybakingtype.md) | [TypeIndex.IsTemporaryBakingType](/engine/7000.0/script-reference/unity/entities/typeindex/istemporarybakingtype.md) | | [Type](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo/type.md) | Returns the System.Type for the component this [TypeManager.TypeInfo](/engine/7000.0/script-reference/unity/entities/typemanager/typeinfo.md) is describing. |
