Class ParallelEnhancer

java.lang.Object
  gpars.ParallelEnhancer

class ParallelEnhancer

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.
