Method Detail

merge

R merge(List<R> results)

Invoked to perform a merge of results. Implementations should not make any assumptions about the order of the results (specifically, the order of the results will not necessarily be the same as partition ids). This also may be invoked multiple times to allow hierarchical merging.

Parameters:

results - the results

Returns:

the merged results.
