Method Details

parseJavadocComment

public JavadocDetailNodeParser.ParseStatus parseJavadocComment(DetailAST javadocCommentAst)

Parses the given Javadoc comment AST into a JavadocDetailNodeParser.ParseStatus object.

This method extracts the raw Javadoc comment text from the supplied DetailAST, creates a new lexer and parser for the Javadoc grammar, and attempts to parse it into an AST of DetailNodes. The parser uses PredictionMode.SLL for faster performance and stops parsing on the first error encountered by using CheckstyleParserErrorStrategy.

Parameters:

javadocCommentAst - the DetailAST node representing the Javadoc comment in the source file

Returns:

a JavadocDetailNodeParser.ParseStatus containing the root of the parsed Javadoc tree (if successful), the first non-tight HTML tag (if any), and the error message (if parsing failed)
