-------------------------------------

             Summary: TargetFilter adds 
                 Key: FELIX-5844
                 URL: https://issues.apache.org/jira/browse/FELIX-5844
             Project: Felix
          Issue Type: Bug
          Components: Declarative Services (SCR)
    Affects Versions: scr-2.1.0
            Reporter: Stefan Bischof


I tryed to get all Services only by filtering the componentpropertys with the 
@Reference Annotation using the target

But DependencyManager.setTargetFilter(String target, int minimumCardinality) 
add a additional classfilter using the interface

 

Or is there any other way to get all Services by using the @Referenc annotation?

MyClass.java
{code:java}
public static final String resourceFilter = "(&(objectClass=null)(" + 
JaxrsWhiteboardConstants.JAX_RS_RESOURCE
 + "=true))";
 @Reference(cardinality = ReferenceCardinality.MULTIPLE, policy = 
ReferencePolicy.DYNAMIC, target = resourceFilter)
public void addResource(Object resource) {
 System.out.println("Add R " + resource);
 }
{code}
 

bundle.jar/OSGI-INF/org.bipolis.MyClass.xml
{code:java}
<?xml version="1.0" encoding="UTF-8"?>
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.3.0"; 
name="org.bipolis.MyClass" immediate="true" activate="activate">
 <implementation class="org.bipolis.MyClass"/>
 <reference name="Resource" cardinality="0..n" policy="dynamic" 
interface="java.lang.Object" 
target="(&amp;(objectClass=null)(osgi.jaxrs.resource=true))" bind="addResource" 
unbind="removeResource"/>
</scr:component> {code}
 

DependencyManager.setTargetFilter -
{code:java}
line 2095:
 final StringBuilder classFilterSB = new StringBuilder();
 classFilterSB.append(OBJECTCLASS_CLAUSE);
 classFilterSB.append(m_dependencyMetadata.getInterface());
 classFilterSB.append(')');
 final String classFilterString = classFilterSB.toString();
 
line 2126: 
 initialReferenceFilterSB.append(classFilterString);
{code}

ServiceRegistry.getServiceReferences(String, SimpleFilter) line: 254 

uses correctly the empty classname;
{code:java}
className :null 

filter SimpleFilter 
:(&(objectClass=java.lang.Object)(&(objectClass=null)(osgi.jaxrs.resource=true))){code}
