# GetSharedValueIndicesBySourceIndex(int)

> 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)
