Syntax

public struct TrackableChanges<T> : IDisposable where T : struct, ITrackable

Type Parameters

Name	Description
T	The ITrackable that can be added and updated.

Constructors

Name	Description
TrackableChanges(int, int, int, Allocator)	Constructs a TrackableChanges<T> from the number of added, updated, and removed trackables. This creates the NativeArrays added, updated, and removed and should be disposed by calling Dispose() on this object.
TrackableChanges(int, int, int, Allocator, T)	Constructor which creates all three arrays and fills the added and updated arrays with repeated copies of defaultValue.
TrackableChanges(void*, int, void*, int, void*, int, T, int, Allocator)	Constructs a TrackableChanges<T> from native memory.

Properties

Name	Description
added	An array of added trackables.
isCreated	Whether the NativeArrays have been created.
removed	An array of TrackableIds that have been removed.
updated	An array of updated trackables.

Methods

Name	Description
CopyFrom(NativeArray<T>, NativeArray<T>, NativeArray<TrackableId>, Allocator)	Creates a new TrackableChanges<T> from existing NativeArrays.
Dispose()	Disposes the added, updated, and removed arrays. Safe to call on a default-constructed TrackableChanges<T>.
