execute the content after the ending mark on the JSP page. 4. execution sequence of simpletag interface methods (1) When the Web Container starts to execute tags, the following method is called to complete tag initialization: The Web Container calls the setjspcontext method of the tag processor object to pass the pagecontext object representing the JSP page to the tag processor object. The Web Container calls the setparent method of the tag processor object and passes the parent Tag Processor o

That is, the same JSP page

is generally inherited when used.The Out object is obtained within the Dotag through Getjspcontext (). Getout ().If the tag body is obtained by getjspbody, the returned object is a jspfragment, and the call Jspfragment.invoke (writer) method writes the contents to the corresponding output, and writes to the page when writer is null.At this time the TLD file to make the relevant changes, bodycontent into tagdependentIf you have more than one label body, you need to use the Jsp:attribute label.Th

program.A.tag.skip_body: Say ... The content between is ignored;B.tag.eval_body_include: Indicates that the contents between the tags are executed normally.3, Doendtag: But the JSP container encounters the end flag of the custom label, it calls the Doendtag () method. The Doendtag () method also returns an integer value used to determine the program's subsequent process.A.tag.skip_page: To stop the execution of the Web page immediately, the non-proce

Recently I made a small function. I made a tree structure using dtree. js and made it using custom labels. I also refer to the online example. The specific implementation is as follows: Treeutil. Java (tree structure directory data processing class) Package Cl. mytree; Create a tree_info table in the database. The fields are node_id integer, parent_id integer, node_name varchar (20), URL varchar (50), and

//TODO: identify what will be done in the future;//FIXME: Identify the content to be corrected or perfected later.???: The place of doubt!!!: Places to be aware ofThe above four hints Xcode has been supported.Add a custom identity and display it in warning at compile time;Target-->build Phases-->editor-->add Run Script build phasesPaste the following code into the shell boxKeywords= "todo:|fixme:|???: |!!!: | XXX: "Find "${srcroot}" \ (-name "*.h"-or-

The personal understanding of the label is that the PHP string is pieced together through Eval () to return the data. The process should be like this, add the definition label to Extending a custom label in thinkphpThe following is an example of output breadcrumbs:Refer to the official built-in label class notation. Build your tag class anywhere, I'm here to put the file name under the Home\mytag folder: class name +class.phpHere take Crumb.class.php

MyEclipse default label todo,xxx,fixme and use of custom labelsSome of the special annotation techniques in MyEclipse include:1. //TODO -Indicates a backlog that has not been completed.2. //XXX --Indicates that the annotated code has realized the function, but the implementation of the scheme is debatable, hoping to improve in the future.3. //Fixme --Indicates that the commented code needs to be corrected.4.
