XStream – Overview XStream is a simple Java-based library to serialize Java objects to XML and vice versa. Features Easy to use − XStream API provides a high-level facade to simplify common use cases. No need to create mapping − XStream API provides default mapping for most of the objects to be serialized. Performance − …
XStream supports JSON by initializing XStream object with an appropriate driver. XStream currently supports JettisonMappedXmlDriver and JsonHierarchicalStreamDriver. Let us now test the code with json handling in XStream. Create a java class file named XStreamTester in C:\>XStream_WORKSPACE\com\tutorialspoint\xstream. File: XStreamTester.java package com.tutorialspoint.xstream; import java.io.Writer; import com.thoughtworks.xstream.XStream; import com.thoughtworks.xstream.annotations.XStreamAlias; import com.thoughtworks.xstream.io.HierarchicalStreamWriter; import com.thoughtworks.xstream.io.json.JsonHierarchicalStreamDriver; import com.thoughtworks.xstream.io.json.JsonWriter; public class …
XStream provides alternative implementations of java.io.ObjectInputStream and java.io.ObjectOutputStream so that streams of objects can be serialized or deserialized from XML. This is particularly useful when large sets of objects are to be processed, keeping one object in memory at a time. Syntax: createObjectOutputStream() ObjectOutputStream objectOutputStream = xstream.createObjectOutputStream( new FileOutputStream(“test.txt”)); Syntax: createObjectInputStream() ObjectInputStream objectInputStream = xstream.createObjectInputStream( …
XStream converters are the key components of the XStream library, which are responsible to convert an object to XML and vice versa. XStream provides numerous converters for common types such as primitives, String, File, Collections, arrays, and Dates. Using Converter Let us use a SingleValueConvertor whose purpose is to convert an object into a single …
XStream supports annotations similarly like automatic configuration instead of coding. In the previous chapter, we’ve seen the following configurations in code. xstream.alias(“student”, Student.class); xstream.alias(“note”, Note.class); xstream.useAttributeFor(Student.class, “studentName”); xstream.aliasField(“name”, Student.class, “studentName”); xstream.addImplicitCollection(Student.class, “notes”); The following code snippet illustrates the use of annotations to do the same work in a much easier way. @XStreamAlias(“student”) //define class level …
Aliasing is a technique to customize the generated XML or to use a particular formatted XML using XStream. Let’s suppose the following XML format is to be used to serialize/de-serialize the Student object. <student name = “Suresh”> <note> <title>first</title> <description>My first assignment.</description> </note> <note> <title>second</title> <description>My second assignment.</description> </note> </student> Based on the above XML …
Before going into the details of the XStream library, let us see an application in action. In this example, we’ve created Student and Address classes. We will create a student object and then serialize it to an XML String. Then de-serialize the same XML string to obtain the student object back. Create a java class …
In this chapter, we will discuss on the different aspects of setting up a congenial environment for Java. Local Environment Setup If you want to set up your environment for Java programming language, then this section explains how to download and set up Java on your machine. Please follow the steps given below to set …
