AW: [udig-devel] objectProperty

[Ingmar Eveslage]

Hello Dirk, hello Jesse,

thanks. This works. realy a bit confusing, but it worked.

Can you explain me, what the target class is? or exactly which objects  
gets evaluated against the property class?

i tried, java.lang.Object and net.refractions.udig.project.ILayer. The  
second i copied from the udig project. it works realy good, but who  
managed the objects which are put in the

public boolean isTrue(ILayer object, String value)

function?

  <object
             targetClass="java.lang.Object">
          <property
                 
class="de.hub.sam.es.managementclient.tool.StationProperty"
                id="isStationProperty">
          </property>
       </object>
       <object
             targetClass="net.refractions.udig.project.ILayer">
          <property
                 
class="de.hub.sam.es.managementclient.tool.LayerFeatureTypeProperty"
                id="LayerFeatureTypeProperty">
          </property>
       </object>

thanks for explaining.
