Constructor TrackableChanges

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.

Declaration

public TrackableChanges(int addedCount, int updatedCount, int removedCount, Allocator allocator)

Parameters

Type	Name	Description
int	addedCount	The number of added trackables.
int	updatedCount	The number of updated trackables.
int	removedCount	The number of removed trackables.
Allocator	allocator	An allocator to use for each of added, updated, and removed arrays.

TrackableChanges(int, int, int, Allocator, T)

Constructor which creates all three arrays and fills the added and updated arrays with repeated copies of defaultValue.

Declaration

public TrackableChanges(int addedCount, int updatedCount, int removedCount, Allocator allocator, T defaultValue)

Parameters

Type	Name	Description
int	addedCount	The number of added trackables.
int	updatedCount	The number of updated trackables.
int	removedCount	The number of removed trackables.
Allocator	allocator	The allocator to use for each of added, updated, and removed arrays.
T	defaultValue	The value with which to fill the added and updated arrays.

TrackableChanges(void*, int, void*, int, void*, int, T, int, Allocator)

Constructs a TrackableChanges<T> from native memory.

Declaration

public TrackableChanges(void* addedPtr, int addedCount, void* updatedPtr, int updatedCount, void* removedPtr, int removedCount, T defaultT, int stride, Allocator allocator)

Parameters

Type	Name	Description
void*	addedPtr	A pointer to a block of memory containing addedCount elements each of size stride.
int	addedCount	The number of added elements.
void*	updatedPtr	A pointer to a block of memory containing updatedCount elements each of size stride.
int	updatedCount	The number of updated elements.
void*	removedPtr	A pointer to a block of memory containing removedCount TrackableIds.
int	removedCount	The number of removed elements.
T	defaultT	A default T which should be used to fill the added and updated arrays before copying data from addedPtr and updatedPtr, respectively.
int	stride	The number of bytes for each element in the addedPtr and updatedPtr arrays.
Allocator	allocator	An allocator to use when creating the added, updated, and removed arrays.

Remarks

Because native code might be using an older version of T, this constructor first fills the added and updated arrays with copies of defaultT before copying the data from the addedPtr and updatedPtr pointers. This ensures that the addition of new fields to T will have appropriate default values.
