| [BufferLookup\<T>](/engine/7000.0/script-reference/unity/entities/bufferlookup1.md) | An array-like object that provides access to buffers, indexed by [Entity](/engine/7000.0/script-reference/unity/entities/entity.md). |

### Remarks

**Obsolete.** Use [ComponentSystemBase.GetBufferLookup](/engine/7000.0/script-reference/unity/entities/componentsystembase/getbufferlookup.md) instead.

Gets a BufferFromEntity\\\<T\\> object that can access a [DynamicBuffer\<T>](/engine/7000.0/script-reference/unity/entities/dynamicbuffer1.md). Assign the returned object to a field of your Job struct so that you can access the contents of the buffer in a Job.
