public abstract class Doclet extends Object
start(RootDoc) method, as described in the
 package
 description.  If the doclet takes command line options,
 it must also implement optionLength and
 validOptions.
  A doclet supporting the language features added since 1.1
 (such as generics and annotations) should indicate this
 by implementing languageVersion.  In the absence of
 this the doclet should not invoke any of the Doclet API methods
 added since 1.5, and
 the results of several other methods are modified so as
 to conceal the new constructs (such as type parameters) from
 the doclet.
 
 To start the doclet, pass
 -doclet followed by the fully-qualified
 name of the starting class on the javadoc tool command line.
| Constructor and Description | 
|---|
| Doclet() | 
| Modifier and Type | Method and Description | 
|---|---|
| static LanguageVersion | languageVersion()Return the version of the Java Programming Language supported
 by this doclet. | 
| static int | optionLength(String option)Check for doclet-added options. | 
| static boolean | start(RootDoc root)Generate documentation here. | 
| static boolean | validOptions(String[][] options,
            DocErrorReporter reporter)Check that options have the correct arguments. | 
public static boolean start(RootDoc root)
public static int optionLength(String option)
This method is required if the doclet contains any options. If this method is missing, Javadoc will print an invalid flag error for every option.
public static boolean validOptions(String[][] options, DocErrorReporter reporter)
This method is not required, but is recommended, as every option will be considered valid if this method is not present. It will default gracefully (to true) if absent.
Printing option related error messages (using the provided DocErrorReporter) is the responsibility of this method.
public static LanguageVersion languageVersion()
This method is required by any doclet supporting a language version newer than 1.1.
