/**
*
* Annotate a JavaBean multi-valued property to support mixed content.
*
*
* The usage is subject to the following constraints:
*
* - can be used with @XmlElementRef, @XmlElementRefs or @XmlAnyElement
*
*
* The following can be inserted into @XmlMixed annotated multi-valued property
*
* - XML text information items are added as values of java.lang.String.
* - Children element information items are added as instances of
* {@link JAXBElement} or instances with a class that is annotated with
* @XmlRootElement.
* - Unknown content that is not be bound to a JAXB mapped class is inserted
* as {@link Element}. (Assumes property annotated with @XmlAnyElement)
*
*
* Below is an example of binding and creation of mixed content.
*
* <!-- schema fragment having mixed content -->
* <xs:complexType name="letterBody" mixed="true">
* <xs:sequence>
* <xs:element name="name" type="xs:string"/>
* <xs:element name="quantity" type="xs:positiveInteger"/>
* <xs:element name="productName" type="xs:string"/>
* <!-- etc. -->
* </xs:sequence>
* </xs:complexType>
* <xs:element name="letterBody" type="letterBody"/>
*
* // Schema-derived Java code:
* // (Only annotations relevant to mixed content are shown below,
* // others are ommitted.)
* import java.math.BigInteger;
* public class ObjectFactory {
* // element instance factories
* JAXBElement<LetterBody> createLetterBody(LetterBody value);
* JAXBElement<String> createLetterBodyName(String value);
* JAXBElement<BigInteger> createLetterBodyQuantity(BigInteger value);
* JAXBElement<String> createLetterBodyProductName(String value);
* // type instance factory
* LetterBody createLetterBody();
* }
*
*
* public class LetterBody {
* // Mixed content can contain instances of Element classes
* // Name, Quantity and ProductName. Text data is represented as
* // java.util.String for text.
* @XmlMixed
* @XmlElementRefs({
* @XmlElementRef(name="productName", type=JAXBElement.class),
* @XmlElementRef(name="quantity", type=JAXBElement.class),
* @XmlElementRef(name="name", type=JAXBElement.class)})
* List getContent(){...}
* }
*
* The following is an XML instance document with mixed content
*
* <letterBody>
* Dear Mr.<name>Robert Smith</name>
* Your order of <quantity>1</quantity> <productName>Baby
* Monitor</productName> shipped from our warehouse. ....
* </letterBody>
*
* that can be constructed using following JAXB API calls.
*
* LetterBody lb = ObjectFactory.createLetterBody();
* JAXBElement<LetterBody> lbe = ObjectFactory.createLetterBody(lb);
* List gcl = lb.getContent(); //add mixed content to general content property.
* gcl.add("Dear Mr."); // add text information item as a String.
*
* // add child element information item
* gcl.add(ObjectFactory.createLetterBodyName("Robert Smith"));
* gcl.add("Your order of "); // add text information item as a String
*
* // add children element information items
* gcl.add(ObjectFactory.
* createLetterBodyQuantity(new BigInteger("1")));
* gcl.add(ObjectFactory.createLetterBodyProductName("Baby Monitor"));
* gcl.add("shipped from our warehouse"); // add text information item
*
*
* See "Package Specification" in javax.xml.bind.package javadoc for
* additional common information.
