groovy and grails

Because it is always so close to the bottom of the hardware that the excitement that began in the 96 is fading away. Programming in life is either a compilation or a C + + or Delphi. Ruby has been excited for a while now and it's groovy. The latter were always marching on the bones of the pioneers. To admire the martyrs is serious, but there is always laughter in life. Groovy's here. The first step is to get the latest Java Jdk:jdk-6u13-windows-i586

The map parameter is one of the most commonly used parameter types in the code of the Groovy language, and we often write the following code naturally: t.testMap(a:1) t.testMap(a:1,b:1) t.testMap(a:1,b:1,c:1) new Person(name:'Tom',sex:23) These are the uses of the map parameter. And so on, we also often want the list parameter to have the same function, for example, we have the following method with the list object as a parameter: class Testor2 { 　

We know that in addition to using hooks to intercept methods, we can also implement methods in various ways. For example, we can implement the method directly in the class, we can add the method through the Expandometaclass during the runtime, and we can add the method to an object separately by Expandometaclass during the run time. All of these ways of directly adding methods, if there is a hook, are to be intercepted by hooks. So, we can say that the system is a priority call hook. and the c

As we all know, in the groovy language, we can use the mop attribute to add properties or methods to the runtime. This addition includes two levels of additions: The first is to add a property or method to a class. That is, if we add a property or method to a class during the runtime, then all the objects instantiated by that class will have this property or method added later. Second, the second is to add a property or method to an object. That is

The interface type described here, in both the Java language and the groovy language, is of course both the base class type and the interface. The term "Dynamic of an interface type" refers to the dynamic addition of a method to a base class or interface during the runtime so that the base class and its subclasses, interface implementations, can access these methods. This feature has always been a feature of interest to me. Because we use a variety o

We talked about mop, that is, "Meta Object Protocol", is the class or object elements, such as names, methods, attributes, and so on, in the run-time of real-time changes, such as the modification method name, attribute name, dynamic increase methods, attributes and so on a class of programming collectively. For example, we have talked about the "InvokeMethod" and "methodmissing" two methods, can be used to enable us to dynamically in the runtime to add methods to a class, it is noteworthy that

Last night to help the old colleague solved a soapui code problem, a long time useless soapui, a lot of things are forgotten, today first summarize the groovy read propertiesFirst spit trough under soapui of Apidocs, I can hardly see what things, official website tips have so little use, but for a long time did not update, a lot of things can not find. And it's almost impossible to debug groovy code in SOAP

List:The list in groovy is similar to an array of Java, such as:def numbers = [1, 2, 3, 4]The groovy list uses the index operator [] to represent the element value, [] is the overload of the GetAt method of the list class, the usage and the character index get a substring similar, and the list can be 、-、 assignment, Mapping (MAP):Mapping is an unordered collection of key-value pairs that you are familiar wi

Document directory 1. Download rovi_base package into your catkin workspace (here is ros_ws) Posted @ from [FreedomShe] I 've been playing the WowWee Rovio car for a while. I sorted out the code I wrote earlier. In ROS Groovy, I encapsulated the CGI interface of WowWee Rovio, the main encapsulation is the control interface (three full wheels, camera) and image interface (in order to save traffic, the video stream is not used to obtain the image,

There is nothing to say. You can understand it at a glance. Bitwise operations From groovy 1.0 Beta 10, groovy supports bitwise operations: (supported from grovvy1.0beta10) _Meaning_ Bitwise left shift operator > Bitwise right shift operator >>> Bitwise unsigned right shift operator | Bi

As a jvm-based language, groovy is increasing in popularity. This article demonstrates how the Groovy.lang.Script class, inherited by GdK, supports custom expression parsing in a Java class.Input:Represents a map structure for a row of data. In practical applications, the most common scenario in which this structure is generated may be access to the database through JDBC, a result set of rows obtained by invoking the WebService service, and so on.Targ

resources is a tricky issue. We need to define choreography, handle errors, and keep trying, and the system must be able to perform well under pressure. As an integrated framework, Mule provides everything we need. Consider an example of a business system that deals with new orders in a format that requires the following: Create a new order by sending an XML entity to the service. Look for the newly created order resource and extract the confirmation from it. Send a confirmation message to

A resilient and dynamic development environment is being given unprecedented attention, and even the scripting language shows this feature, which is exactly what we need, that is, we always need to build an application that is maintainable and that meets our needs. If we want to get involved in scripting language, we should consider a new scripting API provided by Java SE 6: A language-independent framework that allows developers to use scripting languages in Java code. With this new set of APIs

In recent years, AOP (aspect-oriented programming) has been widely used, we apply it to such as print log, permission control and so on. When it comes to AOP, we typically use tools such as spring AOP, and so on. Of course, tools are commonly used to implement system-level AOP, which is typically implemented with the help of configuration documents. When we need to implement a smaller range of AOP, such as AOP for certain methods of a finite number of classes, we generally do not want to use t

1. Program Entry You can write statements directly.You can also add a main method to the first class of the current groovy source file. See below: Class student{ static void Main (args) { print "HI" } } 2. Sample Code System.out.print () print ' hi\n '; for (int i=0;i * But,if the class implements comparable interface, ' = = ' in groovy was same as ' compareTo () ' in Java * /print (stud ENT1==STU

determines whether the property of the field is Boolean and, if so, calls the Isxxxx () method, otherwise the Getxxxx () method is invoked. At the time of the call, the name of the field first gets the corresponding "is" or "get" method name, and then the methods object is obtained, and finally the Invoke method of the object is invoked to get the return value. The whole process is quite tedious. But in the groovy language, we set or get property

The observer model is one of the more commonly used patterns and the basis for other common patterns, such as the MVC pattern, which is a model based on observer mode. In the Java language, the implementation of observer mode is very simple, that is, let the observer inherit the observable class, and let the observer implement the Observer interface. These basics are used in my words--"mantis, Siskin--from an idiom to the Observer model," which is no longer described here. If we have used obse

In the groovy language, there are three ways to analyze methods and properties during the runtime, respectively: First, inherit from the Java language reflection mode. Second, use the "Respondsto" and "Hasproperty" methods. Third, use the "Hasmetamethod" and "Hasmetaproperty" methods. All of the above three methods can be in the runtime to analyze whether a method or attribute exists, I believe we see here, we must think that there is no differenc
