Interface CheckedConsumer<T>

Type Parameters:
T - the type of the input to the operation
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@NullMarked @FunctionalInterface public interface CheckedConsumer<T>
A functional interface representing an operation that accepts a single input argument, returns no result, and may throw a checked exception. This is a variation of the standard Consumer interface, intended for use in scenarios where the operation may involve checked exceptions.

Used as the release parameter of Resource.of(CheckedSupplier, CheckedConsumer) to define the teardown action for a managed resource.

The rationale for providing checked variants of the standard functional interfaces (and the choice of throws Exception over throws Throwable) is documented in ADR-019 — CheckedFunction, CheckedSupplier, CheckedRunnable, CheckedConsumer as first-class interfaces.
