Class Checked

java.lang.Object

com.github.davidmoten.rx.Checked

public final class Checked
extends Object

Utility functions that are useful for brevity when using checked exceptions in lambdas with RxJava.

Instead of

 OutputStream os =  ...;
 Observable<String> source = ...;
 source.doOnNext(s -> {
         try {
             os.write(s.getBytes());
         } catch (IOException e) {
             throw new RuntimeException(e);
         }
     })
     .subscribe();
 

you can write:

 source.doOnNext(Checked.a1(s -> os.write(s.getBytes()))).subscribe();
