JiBX: Bindings Tutorial
This version of the schema represents the same XML document structure as the Listing 9 schema but includes separate type definitions matching each Java class. After reading this tutorial and working through the supplied examples, you will be able to use Tutoorial to generate quality XML schema definitions from your own Java data-structure classes.
JiBX performance consistently measures at the top end of the range, surpassing that of other common tools such as JAXB 2. This gives you ways of handling tutoeial cases that are beyond the normal binding flexibility.
Bind XML message to Java objects using JiBX – JiBX Binding Tutorial
The JiBX documentation provides full details on all these customization options, along jubx more examples of schema generation from code.
The flexibility of the Venetian Blind style is probably not important if you just plan to jigx your Java code as the base for any further changes rerunning BindGen each time your code changesbut it can be nice if you intend to use the schema as a basis for further development.
Instead of letting JiBX build jigx marshaller and unmarshaller for a class based on a mapping element in your binding definition, you tell JiBX to use your own supplied class. When a new instance of the class is needed during unmarshalling, Tutorila uses that no-argument constructor to create the instance. These XML customizations include the actual representation as an element or an attribute of values, the order and names of elements and attributes, whether a value is optional or required, and more.
Subprojects Eclipse Plug-in Introduction. To try this out, open a console in the dwcode1 directory of the installed download and type ant compile bindgen. You’ll look into those later in the tutorial.
Jibx: mapping xml to java
Listing 11 gives a couple of examples of using customization elements for individual values, based on the same example jigx you’ve seen in the earlier examples:. You’ll see how to work with these value customization elements in a later example. If you compare Listing 12 with the Listing 10 sample, you’ll see how the representation has been changed by the latest customizations.
This customization uses both item-name and element attributes. The full sample code is in the sample code’s src directory.
Part 2 covers the flip side of starting from XML schema definitions and generating Java code. Im watch them but, my english terrible and its hard to me read so much text. Two main components of Jibx are Binding compiler and Binding runtime.
Fortunately, you don’t need to understand the binding definition in order to work with JiBX using BindGen binding and schema generation, so this tutorial doesn’t cover the details. The downside of this extended control is that marshallers and unmarshallers are considerably more complex to code than serializers and deserializers. They’re also not as well documented as the normal user interface – all you’ll have to work with is this page, the associated example code, and the JavaDocs for the implementation classes in the org.
Listing 2 shows the generated schema output from BindGen as starter.
The principle behind custom marshallers and unmarshallers is simple: IAliasable interface which is only an indicator interface, with no actual methods defined.
You can also control the XML representation of a value using the includes attribute.
You can try this set of customizations by using the Ant custgen2 target ant compile custgen2 bindto run the complete build. In this case, the nested style results in a schema jobx just three global definitions: By default, BindGen treats all primitive values and simple object values classes with direct XML equivalent types, other than String as attributes and treats all complex object values as child elements.
Java names customarily use a “camelcase” style: On the marshalling side, this uses a supplied version string to select the binding: In this tutorial, you’ll see how to apply the first type of generation: You can see the schema documentation in Listing 2 for each field with a Javadoc in Listing 1and for each global type corresponding to a class with a Javadoc.
The Listing 6 customizations demonstrate both these techniques. Each entry element gives the key as an attribute and the tutrial value as the content.
