Class Parallel<R>

java.lang.Object

de.team33.testing.async.thebe.Parallel<R>

public final class Parallel<R>
extends Object

A tool/utility used to perform a given operation multiple times in parallel threads, with a fixed number of executing threads. Each thread performs the operation at least once and repeats it until all intended threads have effectively started.

The operation is given unique context information each time it is executed, showing an assignment to the executing thread, the absolute start order, and repetition within the executing thread.

Method Summary
