We don't have the ability to retrieve a subset of properties at the moment.

However, you can get individual properties with:

Serializable prop = this.nodeService(nodeRef, QName.createQName("your-uri", "prop-name");‍

Alternatively you could use the data dictionary to get the properties of the type and retrieve them using the node service (useful if you don't know what the properties may be).

Hope that helps.

thanks
i have a other question
i look the classe QName.In this classe there is a function called toPrefixString() .
im my code i retrieve a property in a QName but this function toPrefixString() retrieve only the name but not the prefix .
i dont understand why.
i would like to use this function to do the difference between all the properties and only the custom type property but it don't work.

so when i declare my properties type i add an other prefix in the name:

<type name="custom:advancedFolder">
         <title>Advanced Folder</title>
         <parent>cm:folder</parent>
         <properties>
            <property name="custom:customClient">
               <type>d:text</type>
            </property>
            <property name="custom:customTechno">
               <type>d:text</type>
            </property>
            <property name="custom:customTypeProjet">
               <type>d:text</type>
            </property>
         </properties>
      </type>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

and to do the diffference in the code

if(qname.getLocalName().indexOf("custom") == 0)‍

but it's not very lovely
:wink:

Hi,

toPrefixString() should give you back the short form of your URI plus the local name i.e. "custom:client" this is as opposed to the full form using the URL such as "http://your.custom.uri:client".

getLocalName() returns the part after the : so you should get back "client".

If the toPrefixString() method is not returning the first part it may be because you don't have a namespace prefix resolver. Try using the following:

toPrefixString(NamespacePrefixResolver prefixResolver)‍

You can pass in an instance of the namespace service as the prefix resolver.

oki it work
i add:

 FacesContext context = FacesContext.getCurrentInstance();
NamespaceService nameSpace = Repository.getServiceRegistry(context).getNamespaceService();
if(qname.toPrefixString(nameSpace).indexOf("custom:") == 0){}

thanks

You can try this…

TypeDefinition typeDef = dictionaryService.getType(typeQName);
Map<QName, PropertyDef> propertyDefs = typeDef.getProperties();‍‍
