reduce

public java.lang.Long reduce(java.lang.Long first,
                             java.lang.Long second)

Description copied from interface: Reduction

Specifies a reduction as defined by 2 elements into 1. The reduction must obey the following 2 constraints:

• Associative: the order of evaluating the reduction makes no difference, and
• Commutative: the order of the thread-local values makes no difference.

Specified by:

reduce in interface Reduction<java.lang.Long>

Parameters:

first - The first element in the reduction.

second - The second element in the reduction.

Returns:

The result of reducing first with second.
