Method Detail

runInBackground

public static Stoppable runInBackground(java.lang.Runnable runnable,
                                        @Nullable
                                        java.lang.String threadName)

Execute the given runnable in a background thread

Returns:

The beckground runnable can be interrupted through this object

runInBackground

public static <EX extends java.lang.Exception> Stoppable runInBackground(RunnableWhichThrows<EX> runnable,
                                                                         @Nullable

runInForeground

public static <EX extends java.lang.Exception> void runInForeground(RunnableWhichThrows<EX> runnable)
                            throws EX extends java.lang.Exception

Executes the given runnable.

Throws:

EX extends java.lang.Exception

parallel

public static <EX extends java.lang.Exception> void parallel(RunnableWhichThrows<EX> runnable1,
                                                             RunnableWhichThrows<EX> runnable2,
                                                             Stoppable stoppable)
                     throws EX extends java.lang.Exception

Executes the two runnables in parallel before it returns.

Throws:

EX extends java.lang.Exception

parallel

public static <EX extends java.lang.Exception> void parallel(java.lang.Iterable<? extends RunnableWhichThrows<EX>> runnables)
                     throws EX extends java.lang.Exception

Throws:

EX extends java.lang.Exception

parallel

public static <EX extends java.lang.Exception> void parallel(java.lang.Iterable<? extends RunnableWhichThrows<EX>> runnables,
                                                             java.lang.Iterable<Stoppable> stoppables)
                     throws EX extends java.lang.Exception

Throws:

EX extends java.lang.Exception

parallel(Runnable[], Iterable)

parallel

public static void parallel(java.lang.Runnable[] runnables,
                            java.lang.Iterable<Stoppable> stoppables)

Invokes the run method of all runnables in parallel threads (including the current thread). When the first of these invocations returns, then all threads are interrupted (which awakes them from blocking I/O), and also on all stoppables Stoppable.stop() is called. When all the threads have been joined, this method returns.

runInForeground

public static <R extends RunnableWhichThrows<EX>,EX extends java.lang.Exception> void runInForeground(java.lang.Iterable<R> runnables)
                            throws EX extends java.lang.Exception

Runs all but the last of runnables in the background, and the last of runnables in the foreground.

Throws:

EX extends java.lang.Exception
