X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=70e4d98f6325bbd5f01e400d1801f17fc780bee3;p=clang

clang-format: [Java] Fix class declaration line breaks.

Before:
  @SomeAnnotation()
  abstract
      class aaaaaaaaa<a> extends bbbbbbbbbbbb<b> implements cccccccccccc {
  }

After:
  @SomeAnnotation()
  abstract class aaaaaaaaa<a> extends bbbbbbbbbbbb<b>

  }
