Factory that creates new JAXBContext instances. JAXBContextFactory can be located using ServiceLoader.load(Class<Object>)

Since:9, JAXB 2.3
/** * <p>Factory that creates new <code>JAXBContext</code> instances. * * JAXBContextFactory can be located using {@link java.util.ServiceLoader#load(Class)} * * @since 9, JAXB 2.3 */
public interface JAXBContextFactory {

Create a new instance of a JAXBContext class.

For semantics see JAXBContext.newInstance(Class<?>[], Map<String,?>)

Params:
  • classesToBeBound – List of java classes to be recognized by the new JAXBContext. Classes in classesToBeBound that are in named modules must be in a package that is open to at least the jakarta.xml.bind module. Can be empty, in which case a JAXBContext that only knows about spec-defined classes will be returned.
  • properties – provider-specific properties. Can be null, which means the same thing as passing in an empty map.
Throws:
  • JAXBException – if an error was encountered while creating the JAXBContext, such as (but not limited to):
    1. No Jakarta XML Binding implementation was discovered
    2. Classes use Jakarta XML Binding annotations incorrectly
    3. Classes have colliding annotations (i.e., two classes with the same type name)
    4. The Jakarta XML Binding implementation was unable to locate provider-specific out-of-band information (such as additional files generated at the development time.)
    5. classesToBeBound are not open to jakarta.xml.bind module
  • IllegalArgumentException – if the parameter contains null (i.e., newInstance(null,someMap);)
Returns: A new instance of a JAXBContext.

Create a new instance of a JAXBContext class.

For semantics see JAXBContext.newInstance(String, ClassLoader, Map<String,?>)

The interpretation of properties is up to implementations. Implementations must throw JAXBException if it finds properties that it doesn't understand.

Params:
  • contextPath – List of java package names that contain schema derived classes. Classes in classesToBeBound that are in named modules must be in a package that is open to at least the jakarta.xml.bind module.
  • classLoader – This class loader will be used to locate the implementation classes.
  • properties – provider-specific properties. Can be null, which means the same thing as passing in an empty map.
Throws:
  • JAXBException – if an error was encountered while creating the JAXBContext such as
    1. failure to locate either ObjectFactory.class or jaxb.index in the packages
    2. an ambiguity among global elements contained in the contextPath
    3. failure to locate a value for the context factory provider property
    4. mixing schema derived packages from different providers on the same contextPath
    5. packages are not open to jakarta.xml.bind module
Returns:a new instance of a JAXBContext
