How to use

doThrowUnchecked

method

in

uk.org.lidalia.lang.Exceptions

/**
 * Because this method throws an unchecked exception, when it is called in a method with a return type the compiler
 * does not know the method is exiting, requiring a further line to return null or throw an unchecked exception
 * directly. This generified method allows this to be avoided by tricking the compiler by adding a return statement
 * as so:
 * <pre>
 *     String someMethod() {
 *         try {
 *             somethingThatThrowsException();
 *         } catch (Exception e) {
 *             return throwUnchecked(e, null); // does not actually return, throws the exception
 *         }
 *     }
 * </pre>
 * @param toThrow The throwable that will be thrown, unwrapped and unchecked; must not be null
 * @param returnType trick to persuade the compiler that a method returns appropriately - always pass null here
 * @return Never returns, always throws the passed in exception
 * @throws NullPointerException if toThrow is null
