Java.xml.bind.JAXBElement.getValue() Method
Description
The Java.xml.bind.JAXBElement.getValue() method returns the content model and attribute values for the element.
Declaration
Following is the declaration for java.xml.bind.JAXBElement.getValue() method:
public T getValue()
Parameters
NA
Return Value
Returns the content model and attribute values for the element.
Exception
NA
Example
The following example shows the usage of java.xml.bind.JAXBElement.getValue() method. To proceed, consider the following Student class which will be used to have objects for marshalling and unmarshalling purposes −
package com.tutorialspoint; import javax.xml.bind.annotation.XmlAttribute; import javax.xml.bind.annotation.XmlElement; import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement public class Student{ String name; int age; int id; public String getName(){ return name; } @XmlElement public void setName(String name){ this.name = name; } public int getAge(){ return age; } @XmlElement public void setAge(int age){ this.age = age; } public int getId(){ return id; } @XmlAttribute public void setId(int id){ this.id = id; } public String toString(){ StringBuilder stringBuilder = new StringBuilder(); stringBuilder.append("Student ["); stringBuilder.append("ID = "); stringBuilder.append(id); stringBuilder.append(", Name = "); stringBuilder.append(name); stringBuilder.append(", Age = "); stringBuilder.append(age); stringBuilder.append("]"); return stringBuilder.toString(); } }
Now let us create main class which will show the usage of java.xml.bind.JAXBElement.getValue() method. Here we will create a JAXBElement of a Student object and then get the class of Student. This example get the content model as the Student object and prints the result.
package com.tutorialspoint; import javax.xml.bind.JAXBElement; import javax.xml.namespace.QName; public class JAXBElementDemo { public static void main(String[] args) { //Create a student object Student student = new Student(); //fill details of the student student.setName("Robert"); student.setId(1); student.setAge(12); //create JAXBElement of type Student //Pass it the student object JAXBElement<Student> jaxbElement = new JAXBElement( new QName(Student.class.getSimpleName()), Student.class, student); //get the content values as Student object Student retrivedStudent = jaxbElement.getValue(); //print the value System.out.println( retrivedStudent.toString()); } }
Let us compile and run the above program, this will produce the following result −
Student [ID = 1, Name = Robert, Age = 12]
