retrieve properties type

[abichet]

i add on a document this type :

<type name="custom:advancedFile">
   <title>Advanced File</title>
   <parent>cm:content</parent>
        <properties>
      <property name="custom:client">
         <type>d:text</type>
      </property>
      <property name="custom:techno">
         <type>d:text</type>
      </property>
      <property name="custom:typeProjet">
         <type>d:text</type>
      </property>
   </properties>
</type>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

in edit document mode i set this properties to value.

this code in java bean

Map<QName, Serializable> properties = this.nodeService.getProperties(createdNode);
‍‍

retrieve all properties of the data.

but i want to retrieve only the properties defined in the type  custom:advancedFile

what can i do ?
