Method Details

merge2

static <T,
R,
A extends TwoStepMapper.Mergeable<T,
R>>
A merge2(A target,
 A other)

newCollector

static <T,
R,
A extends TwoStepMapper.Mergeable<T,
R>>
Collector<T,A,R> newCollector(Supplier<A> supplier)

Create a new Collector that can be used with Stream.collect(Collector). Just provide a constructor or factory method reference to create instances of a TwoStepMapper.Mergeable implementation.

merge

void merge(R other)

This method can be used to merge the results from multiple instances. The final results from one instance is merged into another.
