setParallelism

public static void setParallelism(int nThreads)

Set the requested level of parallelism. Note that for interactive use this is usually set through the user interface and shouldn't be modified elsewhere to maintain consistency.

Parameters:

nThreads -

getParallelism

public static int getParallelism()

Get the requested level of parallelism. Other classes that make use of thread pools can use this to help balance multithreading with memory use. The default value is ForkJoinPool.getCommonPoolParallelism().

Returns:
