Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    JAXBContext jc = JAXBContext.newInstance(Foo.class);

    Unmarshaller unmarshaller = jc.createUnmarshaller();
    StringReader xml = new StringReader("<foo><bar>toast</bar></foo>");
    Foo foo = (Foo) unmarshaller.unmarshal(xml);

    System.out.println(foo.isBar());
}

From source file:Main.java
