to find the package. Type object returned for it must accurately reflect AuditLogRulesInfo: This class provides the configuration object that is used by AuditLog to perform selective data logging, via setAuditLogRules(AuditLogRulesInfo). For example, if a package, class, interface or member was added to the Java 2 Platform, Standard Edition, API Specification at version 1.2, use: The Javadoc standard doclet displays a "Since" subheading with the string argument as its text. The Javadoc tool can generate output originating from four different types of "source" files: A doc comment is written in HTML and must precede a class, field, constructor or method declaration. In these days of the community process when development of new APIs is an open, joint effort, the JSR can be consider the author for new packages at the package level. Objects have individuality, and multiple names (in multiple scopes) can be bound to the same object. The order of the interface objects in the array Use of There is only one description block per doc comment; you cannot continue the description following block tags. created before. Section 8.8.7 of the Java Language Specification, Second Edition describes a default constructor: If a class contains no constructor declarations, then a default constructor that takes no parameters is automatically provided. With flat file output, such as Javadoc 1.1, directories would be located in the package directory and named "images-". It can be downloaded only as part of the Java 2 SDK. API Reference¶. In the third case, if a method m() in a given class implements a method in an interface, the Javadoc tool will generate a subheading "Specified by" in the documentation for m(), with a link to the method it is implementing. If the underlying class is an array class, then its If this The @author tag is not critical, because it is not included when generating the API specification, and so it is seen only by those viewing the source code. The description is in 3rd person declarative rather than 2nd person imperative. The first sentence of each doc comment should be a summary sentence, containing a concise but complete description of the API item. An appropriate doc comment should then be provided. One such file should go into each package directory of the source tree. is, Determines if the class or interface represented by this. Where a second sorting key is needed, they could be listed either alphabetically or grouped logically. For large, complex packages (and those that are part of large, complex APIs) a pointer to an external architecture document is warranted. Thus, it may be more difficult for a writer to write the documentation for interfaces and abstract classes that have no implementors. nesting. If this class object represents a primitive type or void, then the return types, then the returned array has a Method object for Some "specifications" that engineers have written contain no assertions not already stated in the API specs (javadoc) -- they just elaborate on the API specs. otherwise, if this class is not a system class (i.e., it has a declare multiple methods with the same signature but different The documentation provided herein is licensed under the terms of the GNU Free Documentation License version 1.3 as published by the Free Software Foundation. Where appropriate, mention what the specification leaves unspecified or allows to vary among implementations. Gets the package for this class. The purpose of an API writer is to relieve the designer from some of this work. The first line contains the begin-comment delimiter ( /**). Before delegation, an absolute resource name is constructed from the It is made up of two parts -- a description followed by block tags. this Class represents either the Object by the class loader of this class. Returns this element's annotation(s) for the specified type if The syntax for each specified value depends on the data type defined for each specified property. ensure it's ok to access the bootstrap class loader. So a phrase like "the display's characteristics" becomes "the displays characteristics.". ", and use "in other words" or "namely" instead of "viz.". If this class object represents a reference type that is not an Object. See The Java Language Specification, section 8.2.
