Class PureJavaReflectionProvider

java.lang.Object

com.thoughtworks.xstream.converters.reflection.PureJavaReflectionProvider

All Implemented Interfaces:

ReflectionProvider

Direct Known Subclasses:

SunLimitedUnsafeReflectionProvider

public class PureJavaReflectionProvider
extends Object
implements ReflectionProvider

Pure Java ObjectFactory that instantiates objects using standard Java reflection, however the types of objects that can be constructed are limited.

Can newInstance: classes with public visibility, outer classes, static inner classes, classes with default constructors and any class that implements java.io.Serializable.

Cannot newInstance: classes without public visibility, non-static inner classes, classes without default constructors. Note that any code in the constructor of a class will be executed when the ObjectFactory instantiates the object.
