Interface UObjDoubleConsumer<T>

All Superinterfaces:

java.util.function.ObjDoubleConsumer<T>

Functional Interface:

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

@FunctionalInterface
 @Generated(value="uk.kludje.annotation.processor.UncheckedFunctionalInterfaceProcessor")
public interface UObjDoubleConsumer<T>
extends java.util.function.ObjDoubleConsumer<T>

TLDR; IMPLEMENT void $accept(T arg0, double arg1) throws Throwable USING A LAMBDA; INVOKE void accept(T arg0, double arg1).

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

void accept(T arg0, double arg1) invokes void $accept(T arg0, double arg1) and throws anything thrown by void $accept(T arg0, double arg1).

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 <T> UObjDoubleConsumer<T> asUObjDoubleConsumer(UObjDoubleConsumer<T> t) provides a convenience method for manufacturing types as an alternative to casting.
