Field Details

SMALL_IMAGE

public static int SMALL_IMAGE

If an image has fewer pixels than this it will not run a concurrent algorithm. The overhead makes it slower.

USE_CONCURRENT

public static boolean USE_CONCURRENT

f set to true it will use a concurrent algorithm

Constructor Details

BoofConcurrency

public BoofConcurrency()

Method Details

setMaxThreads

public static void setMaxThreads(int maxThreads)

Sets the maximum number of threads available in the thread pool and adjusts USE_CONCURRENT. If the number of threads is less than 2 then USE_CONCURRENT will be set to false and the single thread version of code will be called. Otherwise USE_CONCURRENT will be true and the max threads in the pool set to the specified number.

Parameters:

maxThreads - Maximum number of threads. &le 1 means it will not be threaded.

isUseConcurrent

public static boolean isUseConcurrent()

getEffectiveActiveThreads

public static int getEffectiveActiveThreads()

Either returns the number of threads in the thread pool or one if threading is disabled
