All Implemented Interfaces:

GreatestCommonDivisor<C>, java.io.Serializable

public class SGCDParallelProxy<C extends GcdRingElem<C>>
extends GreatestCommonDivisorAbstract<C>

Solvable greatest common divisor parallel proxy. Executes methods from two implementations in parallel and returns the result from the fastest run. Uses timeout on invokeAny() and return fake common divisor 1 in case of timeout.
