Interface ThrowingConsumer<T extends @Nullable Object>

Type Parameters:
T - the type of argument consumed
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface @API(status=STABLE, since="5.0") public interface ThrowingConsumer<T extends @Nullable Object>
ThrowingConsumer is a functional interface that can be used to implement any generic block of code that consumes an argument and potentially throws a Throwable.

The ThrowingConsumer interface is similar to Consumer, except that a ThrowingConsumer can throw any kind of exception, including checked exceptions.

Rationale for throwing Throwable instead of Exception

Although Java applications typically throw exceptions that are instances of Exception, RuntimeException, Error, or AssertionError (in testing scenarios), there may be use cases where a ThrowingConsumer needs to explicitly throw a Throwable. In order to support such specialized use cases, accept(T) is declared to throw Throwable.
