Class SunLimitedUnsafeReflectionProvider

java.lang.Object

com.thoughtworks.xstream.converters.reflection.PureJavaReflectionProvider

com.thoughtworks.xstream.converters.reflection.SunLimitedUnsafeReflectionProvider

All Implemented Interfaces:

ReflectionProvider

Direct Known Subclasses:

SunUnsafeReflectionProvider

public class SunLimitedUnsafeReflectionProvider
extends PureJavaReflectionProvider

Instantiates a new object bypassing the constructor using undocumented internal JDK features.

The code in the constructor will never be executed and parameters do not have to be known. This is the same method used by the internals of standard Java serialization, but relies on internal code (sun.misc.Unsafe) that may not be present on all JVMs.

The implementation will use standard Java functionality to write any fields. This requires Java 5 as minimum runtime and is used as fallback on platforms that do not provide the complete implementation level for the internals (like Dalvik).

Since:

1.4.7
