de.team33.patterns.exceptional.dione.Converter

public final class Converter
extends Object

A tool class that can convert certain functional constructs defined in this module (e.g. XFunction) to more common ones (e.g. Function) that, when executed, will wrap any occurring checked exception in a specific unchecked exception. Any unchecked exception that may occur will remain unaffected.

Use using(Function) to get an instance.

Method Summary

Modifier and Type	Method	Description
final <T, U> BiConsumer<T,U>	biConsumer(XBiConsumer<? super T,? super U,?> xBiConsumer)	Converts an XBiConsumer that may throw a checked exception to a BiConsumer that, when executed, wraps any occurring checked exception as a specific unchecked exception.
final <T, U, R> BiFunction<T,U,R>	biFunction(XBiFunction<? super T,? super U,? extends R,?> xBiFunction)	Converts an XBiFunction that may throw a checked exception to a BiFunction that, when executed, wraps any occurring checked exception as a specific unchecked exception.
final <T, U> BiPredicate<T,U>	biPredicate(XBiPredicate<? super T,? super U,?> xBiPredicate)	Converts an XBiPredicate that may throw a checked exception to a BiPredicate that, when executed, wraps any occurring checked exception as a specific unchecked exception.
final <T> Consumer<T>	consumer(XConsumer<? super T,?> xConsumer)	Converts an XConsumer that may throw a checked exception to a Consumer that, when executed, wraps any occurring checked exception as a specific unchecked exception.
final <T, R> Function<T,R>	function(XFunction<? super T,? extends R,?> xFunction)	Converts an XFunction that may throw a checked exception to a Function that, when executed, wraps any occurring checked exception as a specific unchecked exception.
final <R> R	get(XSupplier<R,?> xSupplier)	Returns the result of a given XSupplier and wraps any checked exception that may occur as a specific unchecked exception.
final <T> Predicate<T>	predicate(XPredicate<? super T,?> xPredicate)	Converts an XPredicate that may throw a checked exception to a Predicate that, when executed, wraps any occurring checked exception as a specific unchecked exception.
final void	run(XRunnable<?> xRunnable)	Runs a given XRunnable that wraps a checked exception that may occur as a specific unchecked exception.
final Runnable	runnable(XRunnable<?> xRunnable)	Converts an XRunnable that may throw a checked exception to a Runnable that, when executed, wraps any occurring checked exception as a specific unchecked exception.
final <R> Supplier<R>	supplier(XSupplier<? extends R,?> xSupplier)	Converts an XSupplier that may throw a checked exception to a Supplier that, when executed, wraps any occurring checked exception as a specific unchecked exception.
static Converter	using(Function<? super Throwable,? extends RuntimeException> wrapping)	Returns a new instance using a given wrapping method.
