From c410b57d55ee10b565356b8595744a804fd2fa2f Mon Sep 17 00:00:00 2001 From: Vlad Ureche Date: Thu, 28 Jun 2012 04:30:30 +0200 Subject: Diagram tweaks #2 - fixed the AnyRef linking (SI-5780) - added tooltips to implicit conversions in diagrams - fixed the intermittent dot error where node images would be left out (dot is not reliable at all -- with all the mechanisms in place to fail gracefully, we still get dot errors crawling their way into diagrams - and that usually means no diagram generated, which is the most appropriate way to fail, I think...) --- test/scaladoc/resources/doc-root/Any.scala | 114 +++++++++++++++++++++ test/scaladoc/resources/doc-root/AnyRef.scala | 131 +++++++++++++++++++++++++ test/scaladoc/resources/doc-root/Nothing.scala | 23 +++++ test/scaladoc/resources/doc-root/Null.scala | 17 ++++ test/scaladoc/run/SI-5780.check | 1 + test/scaladoc/run/SI-5780.scala | 25 +++++ 6 files changed, 311 insertions(+) create mode 100644 test/scaladoc/resources/doc-root/Any.scala create mode 100644 test/scaladoc/resources/doc-root/AnyRef.scala create mode 100644 test/scaladoc/resources/doc-root/Nothing.scala create mode 100644 test/scaladoc/resources/doc-root/Null.scala create mode 100644 test/scaladoc/run/SI-5780.check create mode 100644 test/scaladoc/run/SI-5780.scala (limited to 'test') diff --git a/test/scaladoc/resources/doc-root/Any.scala b/test/scaladoc/resources/doc-root/Any.scala new file mode 100644 index 0000000000..031b7d9d8c --- /dev/null +++ b/test/scaladoc/resources/doc-root/Any.scala @@ -0,0 +1,114 @@ +/* __ *\ +** ________ ___ / / ___ Scala API ** +** / __/ __// _ | / / / _ | (c) 2002-2010, LAMP/EPFL ** +** __\ \/ /__/ __ |/ /__/ __ | http://scala-lang.org/ ** +** /____/\___/_/ |_/____/_/ | | ** +** |/ ** +\* */ + +package scala + +/** Class `Any` is the root of the Scala class hierarchy.
