Class DynamicJAXBContext

java.lang.Object
javax.xml.bind.JAXBContext
org.eclipse.persistence.jaxb.JAXBContext
org.eclipse.persistence.jaxb.dynamic.DynamicJAXBContext

public class DynamicJAXBContext

extends JAXBContext

A specialized JAXBContext for marshalling and unmarshalling DynamicEntities.

DynamicJAXBContext also provides methods to:

• get the DynamicType associated with a given Java name
• get the DynamicType associated with a given XML name
• create a new DynamicEntity given the Java name of its DynamicType
• create a new DynamicEntity given the XML name of its DynamicType

New instances of DynamicJAXBContext must be created with DynamicJAXBContextFactory.

Since:

EclipseLink 2.1

Method Detail

getDynamicClassLoader

public DynamicClassLoader getDynamicClassLoader()

getDynamicType

public DynamicType getDynamicType(java.lang.String javaName)

Obtain a reference to the DynamicType object for a given Java name. If one has not been generated, this method will return null.

Parameters:

javaName - A Java class name, used to look up its DynamicType.

Returns:

The DynamicType for this Java class name.

newDynamicEntity

public DynamicEntity newDynamicEntity(java.lang.String javaName)
                               throws java.lang.IllegalArgumentException

Create a new instance of DynamicEntity for a given Java name. If a DynamicType for this Java class name has not been generated, this method will return null.

Parameters:

javaName - The Java class name to create a new DynamicEntity for.

Returns:

A new DynamicEntity for this Java class name.

Throws:

java.lang.IllegalArgumentException

newDynamicEntity

public DynamicEntity newDynamicEntity(DynamicType dynamicType)

Create a new instance of DynamicEntity for a given DynamicType.

Parameters:

dynamicType - The DynamicType to create a new DynamicEntity for.

Returns:

A new DynamicEntity for this DynamicType.

getEnumConstant

public java.lang.Object getEnumConstant(java.lang.String enumName,
                                        java.lang.String constantName)
                                 throws java.lang.ClassNotFoundException,
                                        javax.xml.bind.JAXBException

Returns the constant named constantName from the enum class specified by enumName.

Parameters:

enumName - Java class name of an enum.

constantName - Name of the constant to get from the specified enum.

Returns:

An Object, the constant from the specified enum.

Throws:

java.lang.ClassNotFoundException

javax.xml.bind.JAXBException

initializeFromSessionsXML

void initializeFromSessionsXML(java.lang.String sessionNames,
                               java.lang.ClassLoader classLoader)

initializeFromMetadata

void initializeFromMetadata(Metadata metadata,
                            java.lang.ClassLoader classLoader,
                            java.util.Map<java.lang.String,?> properties)
                      throws javax.xml.bind.JAXBException

Throws:

javax.xml.bind.JAXBException

refreshMetadata

public void refreshMetadata()
                     throws javax.xml.bind.JAXBException

Description copied from class: JAXBContext

ADVANCED:

Refresh the underlying metadata based on the inputs that were used to create the JAXBContext. This is particularly useful when using the virtual property mappings. The refreshMetadata call could be made in the following way:

org.eclipse.persistence.jaxb.JAXBHelper.getJAXBContext(aJAXBContext).refreshMetadata();

Note:

• As instances of Binder maintain a cache, calling refreshMetadata will not affect instances of Binder. To get the new metadata you must create a new instance of Binder after the refresh metadata call has been made.

Overrides:

refreshMetadata in class JAXBContext

Throws:

javax.xml.bind.JAXBException
