Xstream Annotations


Bellow is my POJO public class AlarmFile { @XStreamAlias("id") @XStreamAsAttribute() private String fileName; @XStreamAlias("text") @XStreamAsAttribute() private String fileId; private String userdata; @XStreamAlias("name") private String name; and i am getting the following This code is available on our GitHub repository as well. The resulting XML is now what we have expected: 15 If you let XStream process the annotations of a type, it will also process all annotations of the related NOW! Class aliasing The first thing we shall change is how XStream refers to the com.thoughtworks.xstream.Blog class. his comment is here

Regards, Jigar Naik Omar Al Kababji Ranch Hand Posts: 357 posted 7 years ago Hi again nothing is impossible, you should use a Converter llike this code: public class UserDataConverter Tell your friends! XStream has to know the alias to turn it into the proper type, but it can find the annotation for the alias only if it has processed the type in advance. While XStream synchronizes the configuration modification, it cannot guard concurrent reads and you may run under certain circumstances into concurrency problems.

I added @XStreamAsAttribute to add xmlns as an attribute .

That's right; but now suppose the book gets translated and we'd like to add an extra attribute to the XML: Robert C.

Xstream Alias Example

If you are looking for basics of java XStream please refer to our earlier tutorial - Java Xstream. However when I tried to adapt the code to support a similar scenario I bumped into a few unexpected problems even though the documentation of this project XStream is actually pretty Xstream Annotations Tell your friends! Xstream Converter Attributes cannot be written for types that are handled by Converter implementations, we have to use a SingleValueConverter and implement our own converter for the Author: class AuthorConverter implements SingleValueConverter {

What is the standard dimension of a picture to be viewed on a wide screen? Leading and trailing whitespaces are normally removed as well as sequential ones! Let's annotate both our type and field and run the tutorial method again: @XStreamAlias("message") class RendezvousMessage { @XStreamAlias("type") private int messageType; public RendezvousMessage(int messageType) { this.messageType = messageType; } } In In order to do this, we shall tell XStream to alias the writer field of the Blog class as an "author" attribute: xstream.useAttributeFor(Blog.class, "writer"); xstream.aliasField("author", Blog.class, "writer"); And now it leaves Xstream Alias Not Working

So the Userdata object ought to contain those data items, no? We desire the same functionality obtained with implicit collections: @XStreamAlias("message") class RendezvousMessage { @XStreamAlias("type") private int messageType; private List content; public RendezvousMessage(int messageType, String ... content) { this.messageType = messageType; this.content = Arrays.asList(content); } } Resulting in an XML which ignores the field name (content) of the list: 15 firstPart secondPart weblink Thanks...

In our case we may now drop the 'messageType', since we are only interested at the content.

Others might claim that the configuration should be clearly stated in a Java class and not mixed with your model, its up to you to pick the best approach in your According to the mailing list, the only workaround is to write a custom converter for the entire class. Anyways... Xstream Documentation Let's start with a custom Message class: package com.thoughtworks.xstream; package com.thoughtworks.xstream; public class RendezvousMessage { private int messageType; public RendezvousMessage(int messageType) { this.messageType = messageType; } } Let's code the XStream

The model First things first, the classes which shall represent our xml files are shown next, beginning with a simple Blog: package com.thoughtworks.xstream; public class Blog { private Author writer; private Amazon S3 Bucket - Creation, Lifecycle, Version, Access What is Object Oriented Programming? Let us go back to the first attempt of our tutorial, but this time we alias the package name instead of the individual classes: public static void main(String[] args) { Blog check over here Concurrency XStream is not thread-safe while it is configured, thread-safety is only guaranteed during marshalling and unmarshalling.

Field aliasing Next we will change the name of the writer tag, but this time we have to use a field alias: xstream.aliasField("author", Blog.class, "writer"); The Martin Clean Code The problem lies in the added attribute 'language'. This is easy using the @XStreamOmitField annotation: @XStreamAlias("message") class RendezvousMessage { @XStreamOmitField private int messageType; @XStreamImplicit(itemFieldName="part") private List content; @XStreamConverter(value=BooleanConverter.class, booleans={false}, strings={"yes", "no"}) private boolean important; @XStreamConverter(SingleValueCalendarConverter.class) private Calendar created =

    This example uses the following annotations @XStreamAlias - Used on the type, field or attribute. You want your element to contain that URL as text and to have a "name" attribute. Why do solar planes have many small propellers instead of fewer large ones? Tell your friends!

    The @XStreamConverter can be used to specify a Converter and pass values to its constructor.
