![]() How to get the string name of the argument's type hint? You can only use getClass()->name if that param is strong typed. ![]() You can do that by doing: $params = $methods->getParameters() Return preg_match('/ (+) /', $export, $matches) I wrote my solution it works for all cases: /**įunction getParameterType(ReflectionParameter $parameter) It looks like similar question already added in How to get parameter type in reflected class method (PHP 5.x)? I think the only way is to export and manipulate the result string: $refParam = new ReflectionParameter(array('Foo', 'Bar'), 0) We'll see this in the section "Setting private fields".PHP Reflection - Get Method Parameter Type As String But if you absolutely want to encapsulate your applet, there is a slightly less elegant version of our technique that you can use. ![]() So there isn't much danger that these fields will be misused. Requiring public access to the parameter fields may seem to go against the object-oriented programming principle of encapsulation, but applets are very rarely accessed by anything other than a browser, and they are not often subclassed. Note that it is harmless to have public fields that don't have corresponding HTML settings - our method will simply ignore them. I included this feature in case you have public fields you want to hide from the HTML coder. You usually won't have to use this scheme. If you only want a subset of those fields to be fetched, you have to adopt a field-naming convention where each field to be included must have a name that begins with a prefix of your liking. Our parameter fetching method initializes every public non-final field that has a corresponding PARAM tag in the HTML document. This article describes a method that does all the parameter fetching for you and may save you from having to type getParameter ever again! What the parameter fetching method does You don't want to leave parameterization until the final stages of your development - if you do, you'll have to hardcode values and compile each time you want to test new settings. Having to do this is really annoying because it's very useful to test various settings by updating the parameters directly from the HTML page during the development stage. This means going back to the init() method each time such alterations occur. Param = parent.getParameter("CHECKER_CELL_WIDTH") ĬHECKER_CELL_WIDTH = Float.valueOf(param).floatValue() Įven if you discipline yourself in parameterizing right from the beginning stages of your development, there will always be a number of fields that will either appear, disappear, or simply change type during the course of development. Param = parent.getParameter("BILLBOARD_DELAY") īILLBOARD_DELAY = Integer.parseInt(param) Get delay (in frames) between billboard messages. Most Java programmers know that, ideally, applets should be configurable from their corresponding HTML document - but how many really are? For my own part, when I neglect to define parameters that would allow Web designers to feed my applets with data of their own, it's usually because I just don't feel like writing an endless sequence of lines that look like this: It lets you examine the structure of a class and provides runtime information on fields, methods, access modifiers, and so on. The class reflection mechanism feature is located in the package. It may be quite a while before you ever need to type getParameter again! The article assumes you have a reasonably good knowledge of the class reflection mechanism, although you could probably figure it out by just looking at the code. This method does all the parameter fetching for you. Paramterization means passing parameters via PARAM tags embedded in the HTML file. This article presents an elegant method for applet parameterization. ![]() This usually involves writing repetitive lines of code in the applet's init() method that will fetch fields from strings returned by the getParameter() method. Developers who have written applets of at least moderate size know that making them configurable from HTML documents can be a tedious chore.
