Package com.tangosol.util.stream

Interface RemoteCollector<T,A,R>

Type Parameters:

T - the type of input elements to the reduction operation

A - the mutable accumulation type of the reduction operation (often hidden as an implementation detail)

R - the result type of the reduction operation

All Superinterfaces:
