public interface Partible<T>

This interface handles the parallel execution of an array of T thorough Parallelizer class. Each execution of a Partible consists in three methods:

1. beforeRun(): is executed once before the execution of all the indices
2. run(T object): is executed once per each object in the array of objects passed as parameter in the exec method of the Parallelizer class. These executions are performed in a parallel way
3. afterRun(): is executed once after the execution of all the indices

Method Summary

Modifier and Type	Method and Description
void	afterRun() Is executed once after execute the method exec.
void	beforeRun() Is executed once before execute the method 'exec'.
void	run(T object) Is executed once for each object in the array of objects passed as parameter in the exec method of the Parallelizer class.

Method Detail

beforeRun

void beforeRun()

Is executed once before execute the method 'exec'. It can be used to initialize resources.

run

void run(T object)

Is executed once for each object in the array of objects passed as parameter in the exec method of the Parallelizer class. These executions are performed in a parallel way. Race conditions must be handle by the developer. This method is no thread safe.

Parameters:

object - Index of the test element.

afterRun

void afterRun()

Is executed once after execute the method exec. It can be used to close resources.
