Fedora Update Notification
2022-02-12 01:14:11.929311

Name : xstream
Product : Fedora 34
Version : 1.4.19
Release : 1.fc34
URL : https://x-stream.github.io
Summary : Java XML serialization library
Description :
XStream is a simple library to serialize objects to XML
and back again. A high level facade is supplied that
simplifies common use cases. Custom objects can be serialized
without need for specifying mappings. Speed and low memory
footprint are a crucial part of the design, making it suitable
for large object graphs or systems with high message throughput.
No information is duplicated that can be obtained via reflection.
This results in XML that is easier to read for humans and more
compact than native Java serialization. XStream serializes internal
fields, including private and final. Supports non-public and inner
classes. Classes are not required to have default constructor.
Duplicate references encountered in the object-model will be
maintained. Supports circular references. By implementing an
interface, XStream can serialize directly to/from any tree
structure (not just XML). Strategies can be registered allowing
customization of how particular types are represented as XML.
When an exception occurs due to malformed XML, detailed diagnostics
are provided to help isolate and fix the problem.
