void acceptThrowing(T argument)
             throws Exception

Performs this operation on the given argument.

Throws:

Exception

fallbackTo

default Consumer<T> fallbackTo(Consumer<T> fallback)

Returns a Consumer performing the given operation on the argument if this operation throws an exception.

Throws:

IllegalArgumentException - if fallback is null

Since:

1.0

fallbackTo

default Consumer<T> fallbackTo(Consumer<T> fallback,
                               Consumer<Exception> exceptionConsumer)

Returns a Consumer performing the given operation on the argument if this operation throws an exception.

Throws:

IllegalArgumentException - if fallback is null

Since:

1.0

orThrow

default ThrowingConsumer<T> orThrow(Class<? extends RuntimeException> exceptionClass)

Returns a ThrowingConsumer throwing an exception of the given type if this operation throws an exception. The original exception thrown by this operation is the cause of the thrown exception.

The exception class must have a constructor accepting a single Throwable as an argument.

Throws:

IllegalArgumentException - if exceptionClass is null

Since:

1.0

orThrow

default ThrowingConsumer<T> orThrow(Class<? extends RuntimeException> exceptionClass,
                                    String message)

Returns a ThrowingConsumer throwing an exception of the given type if this operation throws an exception. The original exception thrown by this operation is the cause of the thrown exception.

The exception class must have a constructor accepting String and Throwable as arguments.

Throws:

IllegalArgumentException - if exceptionClass is null

Since:

1.0

orTryWith

default ThrowingConsumer<T> orTryWith(ThrowingConsumer<? super T> other)

Returns a ThrowingConsumer performing the given operation on the argument if this operation throws an exception.

Throws:

IllegalArgumentException - if other is null

Since:

1.0

orTryWith

default ThrowingConsumer<T> orTryWith(ThrowingConsumer<? super T> other,
                                      Consumer<Exception> exceptionConsumer)

Returns a ThrowingConsumer performing the given operation on the argument if this operation throws an exception.
