public class JavadocTagContinuationIndentationCheck extends AbstractJavadocCheck
Checks the indentation of the continuation lines in block tags. That is whether the continued description of at clauses should be indented or not. If the text is not properly indented it throws a violation. A continuation line is when the description starts/spans past the line with the tag. Default indentation required is at least 4, but this can be changed with the help of properties below.
  • Notes: This check does not validate the indentation of lines inside pre tags.
Since:
6.0
