Method Detail

execute

public void execute(@NonNull
                    java.lang.Runnable command)

Execute given command on the UI thread as soon as possible.

If the current thread is already the UI one, then the given command is executed directly. Else, it is posted on UI thread for later execution.

Specified by:

execute in interface java.util.concurrent.Executor

Parameters:

command - to execute.

executeAsync

public void executeAsync(@NonNull
                         java.lang.Runnable command)

Execute the given command asynchronously on the UI thread.

In all cases, even if the current thread is the UI one, the given command is posted for later execution.

This may be useful in case of not controlled command to safely execute under locking conditions. For instance:

   private Lock _lock = new NonReentrantLock();

   public void foo() {
     _lock.lock();
     new RunOnUiThreadExecutor().executeAsync(this::bar);
     _lock.unlock();
   }

   public void bar() {
     _lock.lock();
     // ... do stuff
     _lock.unlock();
   }
 

Parameters:

command - to execute.
