[cfe-dev] clang-format Java 8 lambda operator

Sun Nov 8 03:06:27 PST 2015

No, there is no option to control this. However, you can add braces around
the lambda body which will help in this case and reduce indentation even
further:

  entries.forEach(entry -> {
    assertTrue(String.format("Host set includes '%s'", entry.getName()),
        hostNames.contains(entry.getName()));
  });
