Struct BufferTypeHandle<T>

A handle to a specific buffer component type, used to access an ArchetypeChunk's component data in a job.

Namespace: Unity.Entities

Syntax

[NativeContainer]
[NativeContainerSupportsMinMaxWriteRestriction]
public struct BufferTypeHandle<T>
    where T : struct, IBufferElementData

Type Parameters

Name	Description
T	The buffer element type

Remarks

Passing a type handle to a job automatically registers the job as a reader or writer of that type, which allows the DOTS safety system to detect potential race conditions between concurrent jobs which access the same component type.

To create a BufferTypeHandle, use GetBufferTypeHandle<T>(Boolean). While type handles can be created just in time before they're used, it is more efficient to create them once during system creation, cache them in a private field on the system, and incrementally update them with Update(SystemBase) just before use.

If the component type is not known at compile time, use DynamicComponentTypeHandle.

Properties

Name	Description
GlobalSystemVersion	The global system version for which this handle is valid.
IsReadOnly	Reports whether this type handle was created in read-only mode.

Methods

Name	Description
ToFixedString()	Returns the formatted FixedString "BufferTypeHandle[type_name_here]".
Update(SystemBase)	When a BufferTypeHandle is cached by a system across multiple system updates, calling this function inside the system's OnUpdate() method performs the minimal incremental updates necessary to make the type handle safe to use.
Update(ref SystemState)	When a BufferTypeHandle is cached by a system across multiple system updates, calling this function inside the system's OnUpdate() method performs the minimal incremental updates necessary to make the type handle safe to use.
