Hello,
for authoring template code like:
## You can modify this page to customize the presentation of your object.
## At first you should keep the default presentation and just save the
document.
#set($class = $doc.getObject('Book store.AuthorClass').xWikiClass)
#foreach($prop in $class.properties)
; $prop.prettyName
: $doc.display($prop.getName())
: $prop.getName()
#end
is used by default. I need to modify this to extract some of the
properties of the object and set it to the Xwiki context to be passed
into another scripts, but besides #foreach I'm not able to extract
individual properties from the properties collection by any possible
way. Some of things I tried was (in my case I'm interested in "name"
property)
$class.properties.name
$class.properties["name"]
#set ($props = $class.properties)
$props
$props.name
$props.get("name")
$class.properties.getName()
($($class.properties).getName())
Keep in mind that there are real Java objects behind these variables,
and you can check the Javadoc (and even the source code) of those objects.
Printing $class.class reveals that you're dealing with an object of type
com.xpn.xwiki.api.Class, and checking the API at
http://platform.xwiki.org/xwiki/bin/view/DevGuide/API shows that the
method you're looking for is:
$class.get("name")
And it's a feature of Velocity to automatically try to use a "get"
method when a more specific method is not found, you can even do:
$class.name
Looking at what $class.properties returns, you can see that it's an
array of properties as in Element[], so you can't retrieve properties by
name from there.
but so far w/o any success. On the other hand the code
like:
#foreach($prop in $class.properties)
#if ($prop.getName() == "name")
I FOUND THE NAME PROP!
#end
#end
is working well, but is not that elegant as if properties would allow
kind of map usage...
Any help on this is highly appreciated.
