Python syntax, such as a Javabean. Or maybe. there is a handy piece of Jython code that would be useful within. Java logic. Whatever the case may be, there are several. In this section, well cover some of the older. Jython within Java, and then go into the. In the end, you. should have a good understanding for how to use a module, script. Jython within your Java application. You will also have an overall understanding for the way that Jython. Object FactoriesPerhaps the most widely used technique used today for incorporating. Jython code within Java applications is the object factory design. This idea basically enables seamless integration between. Java and Jython via the use of object factories. There are. different implementations of the logic, but all of them do have the. Implementations of the object factory paradigm allow one to include. Compiling and executing java programs.

NEW BOOKS FROM OLD Electrifying Classics. Books have changed. Not the words but how books are shared. This simple reading program is going to help you make the most. Jython modules within Java applications without the use of an extra. Moreover, this technique allows for a clean. Jython and Java code through usage of Java. In this section, I will explain the main concept of the. I will show you various. Lets take a look at an overview of the entire procedure from a. Say that youd like to use one of your existing Jython. Java application. Begin by. coding a Java interface that contains definitions for those methods. Java. application. Next, you would modify the Jython module to implement. Java interface. After this, code a Java factory. Py. Object into a Java object. Lastly, take the newly created Java. It may sound like a lot of steps in. I think youll agree that it is. Over the next few sections, I will take you through different. The first example is a simple and. Jython object and. In the second example, well take a look at a very. Jython objects. Each of these methodologies has its own benefit and you can use the. One to One Jython Object FactoriesWe will first discuss the notion of creating a separate object. Jython object we wish to use. This one to one. In order. Jython module using this technique, you must either. Java code. Lets take. Java. application that uses a Jython class representing a building. Listing 1. 0 3. Creating a One To One Object Factory. Building. py A python module that implements a Java interface to create a building objectfromorg. Building. Typeclass. BuildingBuilding. Type definitself,name,address,id self. Building. Nameself returnself. Building. Addressself returnself. Bulding. Idself returnself. We begin with a Jython module named Building. Now, we must first ensure that there are. It is usually a safe bet to place this file at. You can see that our. Building. py object is a simple container for holding building. We must explicitly implement a Java interface within. Jython class. This will allow the Python. Interpreter to coerce. Our second piece of code is the Java interface. Building. py. As you can see from the code. Jython types are going to be coerced into Java types. Java types. Lets take a look at the Java interface next. Building. Type. java Java interface for a building object. Building. Type. String get. Building. Name. public String get. Building. Address. String get. Building. Id. Looking through the definitions contained within the Java. If we. wanted to change the python code a bit and add some code to one of. Java interface. The. Java. This. factory has the job of coercing the python module into a Java. Building. Factory. Object Factory that is used to coerce python module into a. Building. Type. import org. Py. Object. import org. Py. String. import org. Python. Interpreter. Building. Factory. Py. Object building. Class. Create a new Python. Interpreter object, then use it to. In this case, we want to. Once the module is imported than we obtain a reference to. Java variable. public Building. Factory. Python. Interpreter interpreter new Python. Interpreter. interpreter. Building import Building. Class interpreter. Building. The create method is responsible for performing the actual. Java bytecode. public Building. Type create String name, String location, String id. Py. Object building. Object building. Class. Py. Stringname. new Py. Stringlocation. Py. Stringid. return Building. Typebuilding. Object. Building. Type. class. The third piece of code in the example above plays a most important. Jython. code into a resulting Java class. In the constructor, a new. Python. Interpreter is created. We then utilize the. Jython object and store it. Py. Object. Next, there is a static method named create. Jython object into Java. It does so by performing a. Py. Object wrapper itself, and as you can see. The. parameters must also be wrapped by Py. Objects. The coercion takes. Py. Object. wrapper. In order to make object implement our Java interface, we. Employee. Type. class to the. Main. javapackage org. Building. Factory. Building. Type. public class Main. Building. Type building.

Factory. printfactory. BUILDING A, 1. WEST MAIN, 1. BUILDING B, 1. WEST MAIN, 2. BUILDING C, 1. WEST MAIN, 3. The last bit of provided code, Main. You can see that the factory takes care of all the. Main. java is quite small. Simply call the factory. Py. Object and coerce it into Java. This procedure for using the object factory design has the benefit. Jython object from within. Java code. In other words, creating a separate factory for each. Jython object allows for the use of passing arguments into the. Jython object. Since the factory is being. Jython object, we can code the. Py. Object with specific arguments that will be. Jython object. Not. Java developer will know exactly what the new. The procedures performed in this. Jython community. In the next section, well take a look at the. Jython object. Summary of One to One Object FactoryThe key to this design pattern is the creation of a factory method. Python. Interpreter in order to load the desired Jython. Once the factory has loaded the module via. Python. Interpreter, it creates a Py. Object instance of the module. Lastly, the factory coerces the Py. Object into Java code using the. Py. Object tojava method. Overall, the idea is not very difficult to implement and relatively. However, the different implementations come into. Jython module and. Java interface. It is important to note that the. Jython object and. Java. All work that is performed against the. Java object is coded against a corresponding Java. This is a great design because it allows us to change. Jython code implementation if we wish without altering the. The Java code can be. Jython code at will without. Making Use of a Loosely Coupled Object FactoryThe object factory design does not have to be implemented using a. It. is possible to design the factory in such a way that it is generic. Jython object. This technique allows. Singleton. factory that can be used for all Jython objects. It also allows for. For instance. Ive created a project named Ply. Jy. http kenai. Jython. Java application in order to. Jython objects from Java without worrying about the factory. You can go to Kenai and download it now to begin learning about. How To Make Fake Id Templates.
