Method Detail

apply

R apply(R result,
      T input,
      AtomicBoolean reduced)

Applies the reducing function to the current result and the new input, returning a new result. A reducing function can indicate that no more input should be processed by setting the value of reduced to true. This causes the reduction process to complete, returning the most recent result.

Parameters:

result - The current result value

input - New input to process

reduced - A boolean value which can be set to true to stop the reduction process

Returns:

A new result value
