Field Detail

MSG_JAVADOC_MISSED_HTML_CLOSE
public static final String MSG_JAVADOC_MISSED_HTML_CLOSE
Message key of error message. Missed close HTML tag breaks structure of parse tree, so parser stops parsing and generates such error message. This case is special because parser prints error like"no viable alternative at input 'b \n *\n'"
and it is not clear that error is about missed close HTML tag.- See Also:
- Constant Field Values
-
MSG_JAVADOC_WRONG_SINGLETON_TAG
public static final String MSG_JAVADOC_WRONG_SINGLETON_TAG
Message key of error message.- See Also:
- Constant Field Values
-
MSG_JAVADOC_PARSE_RULE_ERROR
public static final String MSG_JAVADOC_PARSE_RULE_ERROR
Parse error while rule recognition.- See Also:
- Constant Field Values
-
MSG_KEY_PARSE_ERROR
public static final String MSG_KEY_PARSE_ERROR
Error message key for common javadoc errors.- See Also:
- Constant Field Values
-
MSG_KEY_UNRECOGNIZED_ANTLR_ERROR
public static final String MSG_KEY_UNRECOGNIZED_ANTLR_ERROR
Unrecognized error from antlr parser.- See Also:

Method Detail
-
getDefaultJavadocTokens
public abstract int[] getDefaultJavadocTokens()
Returns the default javadoc token types a check is interested in.- Returns:
- the default javadoc token types
- See Also:
JavadocTokenTypes
-
visitJavadocToken
public abstract void visitJavadocToken(DetailNode ast)
Called to process a Javadoc token.- Parameters:
ast

JavadocTokenTypes
-
getRequiredJavadocTokens
public int[] getRequiredJavadocTokens()
The javadoc tokens that this check must be registered for.- Returns:
- the javadoc token set this must be registered for.
- See Also:
JavadocTokenTypes
-
setJavadocTokens

Adds a set of tokens the check is interested in.- Parameters:
strRep
- the string representation of the tokens interested in
-
