Interface UIntSupplier

All Superinterfaces:

java.util.function.IntSupplier

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

public interface UIntSupplier
extends java.util.function.IntSupplier

TLDR; IMPLEMENT int $getAsInt() throws Throwable USING A LAMBDA; INVOKE int getAsInt().

A functional interface for handling checked exceptions. See parent type for interface intent.

int getAsInt() invokes int $getAsInt() and throws anything thrown by int $getAsInt().

General example using java.lang.Runnable that reduces 11 lines to a single line. Call someMethodThatThrowsException in throwsNothing:

 public void someMethodThatThrowsException() throws IOException {
   // I/O functionality
 }

 public void throwsNothing(Runnable r) {
   r.run();
 }
 

Before:

 public void yourMethod() throws IOException {
   try {
     throwsNothing(() -> {
       try {
         someMethodThatThrowsException();
       } catch (IOException e) {
         throw new SomeWrapperException(e);
       }
     });
   } catch(SomeWrapperException w) {
     throw (IOException) w.getCause();
   }
 }
 

After:

 public void yourMethod() throws IOException {
   throwsNothing((URunnable) this::someMethodThatThrowsException);
 }
 

Method public static UIntSupplier asUIntSupplier(UIntSupplier t) provides a convenience method for manufacturing types as an alternative to casting.
