Struct NativeArraySharedInt
Merge sort index list referencing NativeArray values. Provide list of shared values, indices to shared values, and lists of source i value indices with identical shared value. As an example: Given Source NativeArray: [A,A,A,B,B,C,C,A,B] Provides: Shared value indices: [0,0,0,1,1,2,2,0,1] Shared value counts: [4,3,2] (number of occurrences of a shared value) Shared values: [A,B,C] (not stored in this structure) Sorted indices: [0,1,2,7,3,4,8,5,6] (using these indices to look up values in the source array would give you [A,A,A,A,B,B,B,C,C]) Shared value start offsets (into sorted indices): [0,4,7]

public struct NativeArraySharedInt : IDisposableConstructors
| Name | Description |
|---|---|
| NativeArraySharedInt(NativeArray<Int32>, Allocator) |
Properties
| Name | Description |
|---|---|
| SharedValueCount | Number of shared (unique) values in source NativeArray |
| SourceBuffer | Original Source Values (passed into constructor) |
Methods
| Name | Description |
|---|---|
| Dispose() | |
| GetSharedIndexArray() | Indices into shared values. For example, given source array: [A,A,A,B,B,C,C,A,B] shared values are: [A,B,C] shared index array would contain: [0,0,0,1,1,2,2,0,1] |
| GetSharedIndexBySourceIndex(Int32) | Index of shared value associated with an element in the source buffer. For example, given source array: [A,A,A,B,B,C,C,A,B] shared values are: [A,B,C] Given the index 2 into the source array (A), the return value would be 0 (A in shared values). |
| GetSharedValueIndexCountArray() | Array of number of occurrences of all shared values. For example, given source array: [A,A,A,B,B,C,C,A,B] shared values are: [A,B,C] Shared value counts: [4,3,2] (number of occurrences of a shared value) |
| GetSharedValueIndexCountBySourceIndex(Int32) | Number of occurrences of a shared (unique) value shared by a given a source index. For example, given source array: [A,A,A,B,B,C,C,A,B] shared values are: [A,B,C] Shared value counts: [4,3,2] (number of occurrences of a shared value) Given the index 2 into the source array (A), the return value would be 4 (for 4 occurrences of A in the source buffer). |
| GetSharedValueIndicesBySharedIndex(Int32) | Array of indices into source NativeArray which share the same shared value For example, given source array: [A,A,A,B,B,C,C,A,B] shared values are: [A,B,C] Shared value counts: [4,3,2] (number of occurrences of a shared value) Shared value start offsets (into sorted indices): [0,4,7] Given the index 0 into the shared value array (A), the returned array would contain [0,1,2,7] (indices into the source array which point to the shared value A). |
| GetSharedValueIndicesBySourceIndex(Int32) | Array of indices into shared value indices NativeArray which share the same source value For example, given Source NativeArray: [A,A,A,B,B,C,C,A,B] shared values are: [A,B,C] Shared value indices: [0,0,0,1,1,2,2,0,1] Given the index 2 into the source array (A), the returned array would contain: [0,1,2,7] (indices in SharedValueIndices that have a value of 0, i.e. where A is in the shared values) |
| GetSortedIndices() | Indices into source NativeArray sorted by value |
| Schedule(JobHandle) | Schedule jobs to collect and sort shared values. |
