Xstream Ignore Unknown Elements


This is no longer true at deserialization time. Nevertheless you have to understand the implications, therefore some words of warning: Chicken-and-egg problem An XStream instance caches all class types processed for annotations. XStream treats now all annotations the same and therefore it no longer auto-detects any annotation by default. thanks darniz Trumbo, Derek wrote Jörg, Thank you very much for investigating my problem in-depth. his comment is here

But, like it or not, sometimes we have no choice, mostly because specification from client says something like “use configuration written in XML file” or something similar. Other parsers support entities, but they might have been turned off to avoid XXE vulnerability. Specialized Converters Not all converters that are part of the XStream package are automatically registered. This support by default will be dropped with the next major version of XStream.

Xstream Ignore Unknown Elements

The stream based model implies, that the caller consumes the individual tokens from the XML parser on demand, while in an event-based model the parser controls the application flow on its content) { this.messageType = messageType; this.content = Arrays.asList(content); } } Resulting in a cleaner XML: 15 firstPart secondPart The implicit annotation can also be used for arrays and maps. WebShere 8 can no longer use XStream 1.4.x? The XML Pull Parser API defines an own mechanism to load the factory for the available XPP implementation.

Therefore Oracle strongly discourages the usage of serializable lambda expressions in the JDK documentation. How secure is iterative password enhancement? since updateDate is not mentioned as a member variable in my class. Xstream Implicit Collection However it may have side effect on implicit collections - therefore it might not be the proper solution for you." This is what I found:     private static XStream xStream

Can I use XStream in an Android application? If we have list of elements that are // not wrapped in a element representing a list (like we have in our XML:

Why does XStream 1.2 no longer read XML generated with XStream 1.1.x? Xstream Alias Not Working Note, that you cannot use your own objects, you have to use what is generated. Let's start with a custom Message class: package com.thoughtworks.xstream; package com.thoughtworks.xstream; public class RendezvousMessage { private int messageType; public RendezvousMessage(int messageType) { this.messageType = messageType; } } Let's code the XStream XStream is a generalizing library, it inspects and handles your types on the fly.


Yes. However, @XStreamAlias is the only annotation that may fail in this case. Xstream Ignore Unknown Elements Starting with XStream 1.3.1 CGLIB support is no longer automatically installed because of possible classloader problems and side-effects, because of incompatible ASM versions. Xstream Converter The attribute field defines the name of the tag used for data contained inside this collection: @XStreamAlias("message") class RendezvousMessage { @XStreamAlias("type") private int messageType; @XStreamImplicit(itemFieldName="part") private List content; public RendezvousMessage(int messageType,

Android basically supports the enhanced mode as well as the Google ApplicationEngine, but the latter's security model limits the types that can be handled. JDomDrivernoDriver turns off DOCTYPE processing to suppress handling of external entities with SAX reader in use. Starting with XStream 1.3.1 you can redefine those attributes to allow the names to be used for your own ones. Anyway, thanks to Chris for simplifying our lives This entry was posted in Java and tagged java, swing, xstream by Rafael Steil. Xstream Annotations

Let's annotate both our type and field and run the tutorial method again: @XStreamAlias("message") class RendezvousMessage { @XStreamAlias("type") private int messageType; public RendezvousMessage(int messageType) { this.messageType = messageType; } } In XomDriveryesXOM uses an internal list to test for available SAX parsers on the classpath and will explicitly enable external entities, even if the SAXBuilder instance is provided manually. However, this is only half the truth. http://trisystech.net/not-working/xstream-annotations.html For real XPath support you will have to implement your own MarshallingStrategy.

Is this the right way to go about doing so? Xstream Namespace There is even a term “XML hell” describing situation when programmer has to deal with many XML configuration files that are hard to comprehend. I checked with version 1.4.3.

Are we in a low CO2 period, compared to the last 590 million years?

You may also use the overloaded version of this method taking an array of types. This is a big issue since any extra element in the xml response will blow off your code. If you create such driver instances on your own, it is your task to setup the XML parser instance on your own.

content) { this.messageType = messageType; this.important = important; this.content = Arrays.asList(content); } } Resulting in the following xml: 15 firstPart secondPart false America/Sao_Paulo Now we face XStream has to know the alias to turn it into the proper type, but it can find the annotation for the alias only if it has processed the type in advance. However, do not use the reflection converter for these types! check over here Which JVMs allow XStream to operate in enhanced mode?

Therefore XStream cannot track the original type of the collection. XStream is for *Java to XML and back* in first place. But exactly in this case the developer knows very well the elements to ignore and that's where he can use the omitField method. > Or would this violate too many of The only issue i have is that if the xml response by a third party by chance have an element in our case like which we were not aware of xstream

How does XStream compare to JAXB (Java API for XML Binding)? But what about classes and situations that aren’t covered by existing converters? What does the letter 'u' mean in /dev/urandom? A little bit of history about my code My xml looks like Car post 12/23/2009 all other fields.

If a new field is added to the class, deserializing an old version will leave the field uninitialized. forumItem.setPostedDate( SearchDataUtils.convertStringToDate(post.getPostedDate(),"yyyy-MM-dd hh:mm:ss")); forumItem.setUpdateDate( Always use proper tools like a profiler to verify where your hotspots are and whether your optimization was really successful or not. If you want to keep these characters you will have to encode them with entities.

XStream's XppDriver never used this lookup mechanism automatically before version 1.4, now it will. By default XStream is written for persistence i.e. Posted by Tomasz Dziurko Apr 22nd, 2013 How-to, Java « Jasmine tests reporter in TeamCity with Scala and SBT Easy Html/Javascript JSON escaping in Scalatra » Comments Please enable JavaScript to thanks darniz Trumbo, Derek wrote: > > Jörg, > > Thank you very much for investigating my problem in-depth.  I appreciate > you taking the time to

XStream architecture is based on IO Readers and Writers, while the XML declaration is the responsibility of XML parsers. In consequence it is possible to adjust the processed XML manually to inject arbitrary objects into the deserialized object graph.
