Method Details

exec

public boolean exec()

Specified by:

exec in class ForkJoinTask<Void>

run

public void run()

Specified by:

run in interface Runnable

getRawResult

public Void getRawResult()

This method cannot be ignored due to being final, so a hostile user supplied Executor could forcibly complete the task and halt future executions. There are easier ways to intentionally harm a system, so this is assumed to not happen in practice.

Specified by:

getRawResult in class ForkJoinTask<Void>

setRawResult

public void setRawResult(Void v)

Specified by:

setRawResult in class ForkJoinTask<Void>

complete

public void complete(Void value)

Overrides:

complete in class ForkJoinTask<Void>

completeExceptionally

public void completeExceptionally(Throwable ex)

Overrides:

completeExceptionally in class ForkJoinTask<Void>

cancel

public boolean cancel(boolean mayInterruptIfRunning)

Specified by:

cancel in interface Future<Void>

Overrides:

cancel in class ForkJoinTask<Void>
