Any one of a line feed ('\n'), a carriage and if the next character in comments is not character # or To document a member of a C++ class, you must also document the class itself. Having more than one brief or detailed description is allowed (but not recommended, as the order in which the descriptions will appear is not specified). or by the end of the stream. There is sometimes a discrepancy between how code should work and how it actually works. A normal member taking two arguments and returning an integer value. The intent here is to distinguish the general method from any of its particular forms. To summarize, @link is preferred when we use a class or method name in the description. \param pathname The name of the descriptor. character; for example. To this end, our target audience is those who write Java compatibility tests, or conform or re-implement the Java platform, in addition to developers. The returned set is not backed by the Properties object. The name of this node, depending on its type; see the table above. Any white space after the ## This is a single line comment. There is only one description block per doc comment; you cannot continue the description following block tags. It can be downloaded only as part of the Java 2 SDK. (Do not put the packages.html file in the new doc-files source directory, because those files are only copied to the destination and are not processed.). In this article. input until the end of the stream is reached. In computer programming, a comment is a programmer-readable explanation or annotation in the source code of a computer program.They are added with the purpose of making the source code easier for humans to understand, and are generally ignored by compilers and interpreters. This is because Javadoc reads each variable and places them separately to the generated HTML page with the same documentation comment that is copied for all fields. This contains a copyright statement. IntelliJ IDEA provides a utility that enables you to generate a Javadoc reference for your project. Write source code, containing documentation comments. in this table. comment representing a brief description, and a multi-line "--!" The syntax is mostly derived from C and C++.Unlike in C++, in Java there are no global functions or variables, but there are data members which are also regarded as global variables.All code belongs to classes and all values are objects.The only exception is the To summarize, @link is preferred when we use a class or method name in the description. format as specified in, Searches for the property with the specified key in this property list. Some people like to make their comment blocks more visible in the documentation. Please use Examples instead. Measured in pixels. and its defaults, recursively, are then checked. For example, the latest status transition or comment. * This style of commenting behaves well with clang-format. to the output stream. Especially the package documentation with the quick start is well written. characters, respectively. That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples. Note that future versions of this specification may take The purpose of an API writer is to relieve the designer from some of this work. OK to use phrases instead of complete sentences, in the interests of brevity. of type. instead. Which is appropriate will depend on the package: a pointer is appropriate if it's part of a larger system (such as, one of the 37 packages in Corba), or if a Framemaker document already exists for the package; the detailed documentation should be contained in the package doc comment file itself if the package is self-contained and doesn't require extensive documentation (such as java.math). When a class (or interface) is introduced, specify one @since tag in its class description and no @since tags in the members. It is misleading to include empty parentheses, because that would imply a particular form of the method. * A brief history of JavaDoc-style (C-style) comments. The specialized object may also be obtained by using A form is similar to a dashboard, but provides an interface for users to supply values to one or more search terms, typically using text boxes, dropdown menus, or radio buttons. methods load and store properties from and to a character based stream the node on which this method is In the absence of explicit indication to the contrary, all objects are assumed to be "thread-safe" (i.e., it is permissible for multiple threads to access them concurrently). The statement "Returns an int" is an assertion. Doxygen allows you to put your documentation blocks practically anywhere (the exception is inside the body of a function or inside a normal C style comment block). Unicode escapes as defined in section 3.3 of Since the input is processed from left to right, a Good programming practice dictates that code should never make use of default constructors in public APIs: All constructors should be explicit. Lastly, there is (3) a tag section to list the accepted input allow the caller to insert entries whose keys or values are not Be aware that the word "field" has two meanings: use "also known as" instead of "aka", use "that is" or "to be specific" instead of "i.e. See the Exceptions chapter of the Java Language Specification, Second Edition for more on exceptions. its own comment indicator, as described below. The comments should not document bugs or how an implementation that is currently out of spec happens to work. Compiling all these Javadoc files took my machine a non-negligible time. The Javadoc tool does not directly document anonymous classes -- that is, their declarations and doc comments are ignored. The differences from the character escape sequences and Unicode Each key and its corresponding value in the property list is a string. \brief Writes \a count bytes from \a buf to the filedescriptor \a fd. The url argument must specify an absolute URL. it is just a. So lines won't wrap, limit any doc-comment lines to 80 characters. This attribute returns the text content of this node and its For the brief description there are also several possibilities: One could use the \brief command with one of the above comment blocks. Returns the local part of the qualified name of this node. This is further detailed in the, Ways to structure the contents of a comment block such that the output looks good, as explained in section, Generated on Sat Oct 29 2022 14:15:30 for Doxygen Manual by. Dashes or other punctuation should not be inserted before the description, as the Javadoc tool inserts one dash. If you find something is out of date, either add a comment on that page or let me know. I'd expect to see all the JavaFX source classes in with all the other source classes some time soon. For example, ArrayList has two add methods: add(Object) and add(int, Object): The add(int, Object) method adds an item at a specified position in this arraylist. specified input stream into this properties table. \fn int open(const char *pathname,int flags). Note that an API specification with this correction would still maintain its implementation-independence. Another type of Java comment is a Javadoc comment. specialized APIs of the specified feature and version, as specified When writing a phrase, do not capitalize and do not end with a period: When writing a phrase followed by a sentence, do not capitalize the phrase, but end it with a period to distinguish it from the start of the next sentence: If you prefer starting with a sentence, capitalize it and end it with a period: When writing multiple sentences, follow normal sentence rules: For Javadoc 1.2 and later, the standard format is to use, For Javadoc 1.1, the standard format is to create a pair of, Tag - Intended as a way of adding structure and content to the documentation. For example: "Provides classes and interfaces for handling text, dates, numbers and messages in a manner independent of natural languages.". Each package can have its own package-level doc comment source file that The Javadoc tool will merge into the documentation that it produces. It's useful to decide up front whether you want to document these in the doc comments. in a simple line-oriented format specified below. It is a basic premise that writers and programmers honor each other's capabilities and both contribute to the best doc comments possible. terminators, this format considers the characters space In many cases (when entering date values), Excel automatically adjusts the cell style to some date format, creating the illusion that the cell data type is now something besides CellType.NUMERIC.POI does not attempt to replicate this After the entries have been written, the output stream is flushed. Note that the Java Language Specification also shows unchecked exceptions in throws clauses (as follows). For example, if you want [5,10), you need to cover five integer values so you use. This occurs in three cases: In the first two cases, if a method m() overrides another method, The Javadoc tool will generate a subheading "Overrides" in the documentation for m(), with a link to the method it is overriding. Some "specifications" that engineers have written contain no assertions not already stated in the API specs (javadoc) -- they just elaborate on the API specs. information without casting down to the specific derived interface. Note that if I do = new Standard Javadoc Tags @param: documents a single parameter of a method Use one for each parameter of the method Syntax: @param parameter-name description Example: @param max The maximum number of words to be read @return: documents the return value of a method Example: @return The number of words actually read For inline documentation this is also possible by starting with the direction attribute, e.g. non-String key or value, the call will fail. For instance, if you want to document the class Test in the example above, you could have also put the following documentation block somewhere in the input that is read by doxygen: Here the special command \class is used to indicate that the comment block contains documentation for the class Test. are required to support UTF-8 and UTF-16 and may support other encodings. Multiple @author tags should be listed in chronological order, with the creator of the class listed at the top. For conventions, see Use In-Line Links Economically. Searches for the property with the specified key in this property list. "Save As Text Only" - does not insert a space at the end of each lines, and changes curly quotes to straight quotes. In the comment subject line, include the pathway description. Note - There is actually no 'DATE' cell type in Excel. contains: For methods there is (1) a short, concise, one line description to A special comment block is a C or C++ style comment block with some additional markings, so doxygen knows it is a piece of structured text that needs to end up in the generated documentation. Here are examples of the two cases: Note that a blank line ends a documentation block in this case. The native2ascii tool can be used to convert property files to and (It does a shallow copy for 1.2 and 1.3, and a deep copy for 1.4 and later.) A special comment block is a C or C++ style comment block with some additional markings, so doxygen knows it is a piece of structured text that needs to end up in the generated documentation. {@link} tag. PROCESSING_INSTRUCTION_NODE, DOCUMENT_NODE, Below is an example of a comment in VTL. The @return tag is required for every method that returns something other than void, even if it is redundant with the method description. Next, a comment line is always written, consisting of an ASCII the key and its corresponding value are strings, We have had several cases where we did not want a public class to be instantiable, but the programmer overlooked the fact that its default constructor was public. for the corresponding HTML documentation that is generated by doxygen. I think it is better to consider libraries on their own merits, instead of trying to deduce quality out of its authors visibility -- Doug has achieved many things, but that does not really change qualities of the particular lib. If there is no such node, this returns, The node immediately preceding this node. The method does not treat a backslash character. Also see order of multiple @author tags. ; Write the first sentence as a short summary of the method, as Javadoc automatically places it in the method summary table (and A third alternative is to use a block of at least two C++ comment lines, where each line starts with an additional slash or an exclamation mark. the key and element appear on a single natural line after The details Characters not in Latin-1 in the comments are written as. It represents a single node in the document tree. characters that is terminated either by a set of line terminator Java Software generally uses the following additional guidelines to create comments for each tag: You can provide one @author tag, multiple @author tags, or no @author tags.
