# GetSharedValueIndexCountBySourceIndex(int)

> 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).
