- Type Parameters:
T
- the type of argument supplied
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
ThrowingSupplier
is a functional interface that can be used to
implement any generic block of code that returns an object and
potentially throws a Throwable
.
The ThrowingSupplier
interface is similar to
Supplier
, except that a ThrowingSupplier
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 ThrowingSupplier
needs to
explicitly throw a Throwable
. In order to support such specialized
use cases, get()
is declared to throw Throwable
.
