public class WriteTagCheck
extends AbstractCheck

Requires user defined Javadoc tag to be present in Javadoc comment with defined format. To define the format for a tag, set property tagFormat to a regular expression. Property tagSeverity is used for severity of events when the tag exists. No violation reported in case there is no javadoc.

• Property tag - Specify the name of tag. Type is java.lang.String. Default value is null.
• Property tagFormat - Specify the regexp to match tag content. Type is java.util.regex.Pattern. Default value is null.
• Property tagSeverity - Specify the severity level when tag is found and printed. Type is com.puppycrawl.tools.checkstyle.api.SeverityLevel. Default value is info.
• Property tokens - tokens to check Type is java.lang.String[]. Validation type is tokenSet. Default value is: INTERFACE_DEF, CLASS_DEF, ENUM_DEF, ANNOTATION_DEF, RECORD_DEF.
