groovyx.gpars
[Groovy] Class ParallelEnhancer

java.lang.Object
  groovyx.gpars.ParallelEnhancer

final class ParallelEnhancer
extends java.lang.Object

ParallelEnhancer allows classes or instances to be enhanced with parallel variants of iterative methods, like eachParallel(), collectParallel(), findAllParallel() and others. These operations split processing into multiple concurrently executable tasks and perform them on the underlying instance of the ForkJoinPool class from JSR-166y. The pool itself is stored in a final property threadPool and can be managed through static methods on the ParallelEnhancer class. All enhanced classes and instances will share the underlying pool. Use the getThreadPool() method to get hold of the thread pool.

ParallelEnhancer

ParallelEnhancer()

Method Detail

enhanceClass

static void enhanceClass(java.lang.Class clazz)

Enhances a class and so all instances created in the future by mixing-in an instance of Parallel. Enhancing classes needs to be done with caution, since it may have impact in unrelated parts of the application.

enhanceInstance

static java.lang.Object enhanceInstance(java.lang.Object collection)

Enhances a single instance by mixing-in an instance of Parallel.

getThreadPool

static Pool getThreadPool()

Retrieves the underlying pool
