[xwiki-devs] Is it possible to make a Comparator that compares XWiki objects by its properties?
I want to make such a Comparator so that I can sort objects retrieved by $xwiki.getObjects("Class") If I had the Comparator, I'd be able to pass it to a collection sort method and sort objects. I'm planning to make that Comparator in a groovy snippet. I may be able to make a Component for that even. Is it possible? If it was possible, would you give me some hints?
Ouch, there is a typo. $xwiki -> $doc #set($services=$xwiki.getDocument("Private.Snowberry Network Services").getObjects("Private.NetworkServices")) #foreach($prop in $services[0].getProperties()) $services[0].getProperty($prop.getName()).getName() = $services[0].getProperty($prop.getName()).getProperty().getClassType() #end The velocity snippet above produced an output. port = com.xpn.xwiki.objects.LongProperty protocol = com.xpn.xwiki.objects.StringListProperty application = com.xpn.xwiki.objects.StringProperty description = com.xpn.xwiki.objects.StringProperty service = com.xpn.xwiki.objects.StringProperty firewalled = com.xpn.xwiki.objects.IntegerProperty It appears that objects returned from $doc.getObjects("Class") have properties that belong to com.xpn.xwiki.objects package.

I guess I will have to implement a Comparator that compares each of the following properties in the com.xpn.xwiki.objects package. BaseStringProperty DateProperty DoubleProperty FloatProperty IntegerProperty LongProperty NumberProperty Am I doing it right? or is it a bad idea to make separate comparison codes for each of those properties?

I tried $sorttool, and it didn't work on XWiki objects. On http://velocity.apache.org/tools/devel/javadoc/org/apache/velocity/tools/gen..., I saw "The sort method takes two parameters a collection and a property name or an array of property names. The property names and corresponding methods must conform to java bean standards since commons-beanutils is used to extract the property values." XWiki Objects don't support java bean standards. I guess they could be extracted by $obj.getProperty("prop").getProperty().getValue() The problem now is to figure out the right sort algorithms for sorting based on multiple properties.

OK, $obj.getProperty("prop").getValue() gets the desired values. $sorttool.sort conforms only to java bean standards. I'll implement something like $sorttool.*sort<http://velocity.apache.org/tools/releases/1.4/javadoc/org/apache/velocity/to..., java.util.List)>*(java.util.Collection collection, java.util.List properties) that conforms to XWiki Object standards.

Hi, I`ve recently published a snippet [1] that provides a macro for sorting lists of XWiki objects in velocity. As for platform, we should probably either include such a macro in macros.vm, or extend SortTool and expose a method for handling XWiki objects.

I read the code, but it doesn't sort by multiple properties. I'm writing components that help sort by properties. On Fri, Nov 16, 2012 at 11:04 PM, Eduard Moraru <enygma2002@gmail.com>wrote:
