A concrete class inherits all the properties and methods of the abstract class that it extends Because a concrete class is subclassed from another class, it s also, perhaps not surprisingly, called a subclass Concrete classes are different from abstract classes in two important ways: Specific methods and properties: Their methods and properties are specific That means that if you have an enemy object class, it might contain a method called targetPlayer That s a method that only enemy objects would find useful However, the enemy object class will also be able to access any of the general properties, like color, that it shares with other classes that extended the same abstract class that it has Instantiated: Concrete classes are instantiated That means that you actually make objects from them using the new operator. zxing barcode reader java download BarCode Reader Free Java App - Download for free on PHONEKY

So, you can do this: var concreteObject:ConcreteClass = new ConcreteClass(); But you should never do this: var abstractClass:AbstractClass = new AbstractClass(); Again, abstract classes should never be instantiated They should be written for the sole purpose of being extended by other classes They re puppet masters, never seen on the stage, but quietly pulling the strings in the dark behind the curtains You can think of an abstract class as a concrete class s parent The kids go out to play, and the parent class keeps a dutiful eye on them from the kitchen window To avoid confusion with AS30 s use of the keyword parent for display objects, abstract classes are referred to as a superclass AS30 has a keyword called super, which lets you access the abstract class from the concrete class, and you ll see how this is used in the examples ahead. java barcode reader api open source Welcome to Barcode4J

This is partially because of the increasingly constrained project schedules, but also because of the growing complexity of application development. This problem is compounded by the myriad ways in which development teams have historically gone about creating access schemes. The Security Application Block was created to simplify and standardize the way that applications authorize users and cache security information within an application. It also allows developers to extend the application block to handle more complicated authorization schemes. This chapter describes the makeup of the Security Application Block, how to use it in an application, and how to create custom authorization and security cache providers. (this.postURL) from the form.action value. Next, the root form XML element is created and assigned to the name of the form. Then the individual HTML form elements are added to the state by iterating the collection form.elements. All HTML form elements are added to the XML data structure so long as the elements are not of type submit or reset. In the saveForm method implementation, only text box elements can be persisted. Normally, though, all HTML form elements could be persisted, but for this explanation the implementation was kept simple. Calling the method saveState, which is implemented as follows, starts the saving of the state: saveState : function() { var buffer = "<" + this.constStateTag + ">"; buffer += "<" + this.constHtmlPageStateTag + ">\n"; buffer += this.onSaveState() buffer += "</" + this.constHtmlPageStateTag + ">\n"; buffer += "</" + this.constStateTag + ">"; var request = new Asynchronous(); var thisReference = this; var oldPath = location.pathname; request.openCallback = function( xmlhttp) { if( location.hash.length == 0) { xmlhttp.setRequestHeader( thisReference.constPageStateHeader, "none"); } else { xmlhttp.setRequestHeader( thisReference.constPageStateHeader, location.hash.slice(1)); } Actually, I should qualify this example slightly It s acceptable, and often preferable, to type the concrete class as the abstract class, like this: var concreteObject:AbstractClass = new ConcreteClass(); concreteObject has an AbstractClass type, but it s still being instantiated as a ConcreteClass Why would you want to do this Because it allows you keep your code really general It means that if you have another class that also extends the abstract class, you can instantiate it like this: var anotherClass:AbstractClass = new AnotherClass(); Because both classes are typed as the AbstractClass, you can use either of them in a method that accepts AbstractClass objects in its parameters public function someMethod(gameObject:AbstractClass):void {. java code 39 barcode ZXing – opensource .google.com
