From 66469e04fe35e5ceb3723cb563379a03e4883101 Mon Sep 17 00:00:00 2001 From: Reinier Zwitserloot Date: Tue, 6 Feb 2018 22:12:42 +0100 Subject: [var] various upgrades to var: * var is promoted to the main package. * It is no longer an opt-in thing. * bug: var (unlike val) is allowed in old-style for loops, but if you multi-init: for (var i = 0, j="Foo";;), you now get an error that you can't do that. * tests both for the multi-for situation and the new main package variant. --- src/core/lombok/var.java | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100644 src/core/lombok/var.java (limited to 'src/core/lombok/var.java') diff --git a/src/core/lombok/var.java b/src/core/lombok/var.java new file mode 100644 index 00000000..63a70213 --- /dev/null +++ b/src/core/lombok/var.java @@ -0,0 +1,35 @@ +/* + * Copyright (C) 2010-2018 The Project Lombok Authors. + * + * Permission is hereby granted, free of charge, to any person obtaining a copy + * of this software and associated documentation files (the "Software"), to deal + * in the Software without restriction, including without limitation the rights + * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell + * copies of the Software, and to permit persons to whom the Software is + * furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in + * all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
