Class SimpleXmlWrappers

java.lang.Object
  org.carrot2.util.simplexml.SimpleXmlWrappers

public class SimpleXmlWrappers
extends Object

Enables SimpleXML-based serialization of collections of arbitrary types, also those contained in libraries. Depending on the actual type, 3 wrapping scenarios are possible:

• Primitive types. Primitive types, and also Class, String and Enum, are handled directly by SimpleXmlWrapperValue, no extra code is required for serialization / deserialization.
• SimpleXML-annotated types. Types annotated with SimpleXML's Root annotation will not be wrapped and serialized / deserialized directly by SimpleXML
• Other types. For any other types, a ISimpleXmlWrapper implementation must be registered using the addWrapper(Class, Class) method.

Method Detail

addWrapper

public static <T> void addWrapper(Class<T> wrappedClass,
                                  Class<? extends ISimpleXmlWrapper<? super T>> wrapperClass)

Registers a new ISimpleXmlWrapper. If a wrapper for the provide wrappedClass already exists, it will be replaced with the new value. The wrapper mapping added using this method will be strict, it will apply only to objects of wrappedClass, but not its subclasses.

Parameters:

wrappedClass - type to be wrapped

wrapperClass - class name of the ISimpleXmlWrapper implementation to wrap wrappedClass

See Also:

addWrapper(Class, Class, boolean)

addWrapper

public static <T> void addWrapper(Class<T> wrappedClass,
                                  Class<? extends ISimpleXmlWrapper<? super T>> wrapperClass,
                                  boolean strict)

Registers a new ISimpleXmlWrapper. If a wrapper for the provide wrappedClass already exists, it will be replaced with the new value.

Parameters:

wrappedClass - type to be wrapped

wrapperClass - class name of the ISimpleXmlWrapper implementation to wrap wrappedClass

strict - if true, the mapping will apply only to objects of wrappedClass, but not to its subclasses. If false, if no exact mapping is found for wrappedClass, the first available superclass mapping will be sought.
