com.diffplug.common.base.Errors.Rethrowing

All Implemented Interfaces:

Consumer<Throwable>

Enclosing class:

Errors

public static class Errors.Rethrowing
extends Errors

An Errors which is guaranteed to always throw a RuntimeException.

If we want to wrap a method with a return value, it’s pointless to specify a default value because if the wrapped method fails, a RuntimeException is guaranteed to throw.

Method Detail

get

public <T> T get(Throwing.Supplier<T> supplier)

Attempts to call supplier and rethrows any exceptions as unchecked exceptions.

wrap

public <T> Supplier<T> wrap(Throwing.Supplier<T> supplier)

Returns a Supplier which wraps supplier and rethrows any exceptions as unchecked exceptions.

wrap

public <T,R> Function<T,R> wrap(Throwing.Function<T,R> function)

Returns a Function which wraps function and rethrows any exceptions as unchecked exceptions.

If you are getting an error about the method wrap is ambiguous, use wrapFunction(com.diffplug.common.base.Throwing.Function) or {@link #wrapPredicate(com.diffplug.common.base.Throwing.Predicate).

wrap

public <T> Predicate<T> wrap(Throwing.Predicate<T> predicate)

Returns a Predicate which wraps predicate and rethrows any exceptions as unchecked exceptions.

If you are getting an error about the method wrap is ambiguous, use wrapFunction(com.diffplug.common.base.Throwing.Function) or {@link #wrapPredicate(com.diffplug.common.base.Throwing.Predicate).

wrapFunction

public <T,R> Function<T,R> wrapFunction(Throwing.Function<T,R> function)

Returns a Function which wraps function and rethrows any exceptions as unchecked exceptions.

wrapPredicate

public <T> Predicate<T> wrapPredicate(Throwing.Predicate<T> predicate)

Returns a Predicate which wraps predicate and rethrows any exceptions as unchecked exceptions.
