Interface ThrowingConsumer<T>
-
- 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>
ThrowingConsumer
is a functional interface that can be used to implement any generic block of code that consumes an argument and potentially throws aThrowable
.The
ThrowingConsumer
interface is similar toConsumer
, except that aThrowingConsumer
can throw any kind of exception, including checked exceptions.Rationale for throwing
Throwable
instead ofException
Although Java applications typically throw exceptions that are instances of
Exception
,RuntimeException
,Error
, orAssertionError
(in testing scenarios), there may be use cases where aThrowingConsumer
needs to explicitly throw aThrowable
. In order to support such specialized use cases,accept(T)
is declared to throwThrowable
.
