Class JavadocParagraphCheck

  • All Implemented Interfaces:
    Configurable, Contextualizable
    public class JavadocParagraphCheck
extends AbstractJavadocCheck

    Checks the Javadoc paragraph.

    Checks that:

    • There is one blank line between each of two paragraphs.
    • Each paragraph but the first has <p> immediately before the first word, with no space after.
    • Property violateExecutionOnNonTightHtml - Control when to print violations if the Javadoc being examined by this check violates the tight html rules defined at Tight-HTML Rules. Type is boolean. Default value is false.
    • Property allowNewlineParagraph - Control whether the <p> tag should be placed immediately before the first word. Type is boolean. Default value is true.

    To configure the default check: 

     <module name="JavadocParagraph"/>

    By default, the check will report a violation if there is a new line or whitespace after the <p> tag: 

     /**
  * No tag (ok).
  *
  * <p>Tag immediately before the text (ok).
  * <p>No blank line before the tag (violation).
  *
  * <p>
  * New line after tag (violation).
  *
  * <p> Whitespace after tag (violation).
  *
  */
 public class TestClass {
 }

    To allow newlines and spaces immediately after the <p> tag: 

     <module name="JavadocParagraph">
   <property name="allowNewlineParagraph" value="false"/>
 </module>

    In case of allowNewlineParagraph set to false the following example will not have any violations: 

     /**
  * No tag (ok).
  *
  * <p>Tag immediately before the text (ok).
  * <p>No blank line before the tag (violation).
  *
  * <p>
  * New line after tag (ok).
  *
  * <p> Whitespace after tag (ok).
  *
