Knut,
here is my �little� HiveMindTestCase (7 files):
playground.IPing.java:
package playground;
public interface IPing {
String ping();
}
playground.IPingHolder.java:
package playground;
import playground.IPing;
public interface IPingHolder {
IPing getPing();
}

public static Class propertyType;
public ObjectProviderMock() {
super();
}
/**
* Interprets the locator as a service id, and passes it to
* [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> Module#getService(String,
Class)}.
*/
public Object provideObject( Module contributingModule, Class propertyType,
String locator, Location location ) {
ObjectProviderMock.propertyType = propertyType;
return new Ping();
}
}
playground.ObjectProviderTest.java:
package playground;
import org.apache.hivemind.Registry;

public class ObjectProviderTest extends HiveMindTestCase {
public void testPingHolderConstructor() throws Exception {
Registry registry = buildFrameworkRegistry( "objectprovidertest.xml" );
IPingHolder service = (IPingHolder) registry.getService(
"playground.PingHolderConstructor", IPingHolder.class );
service.getPing().ping();
assertSame( IPing.class, ObjectProviderMock.propertyType );
}
public void testPingHolderSetter() throws Exception {
Registry registry = buildFrameworkRegistry( "objectprovidertest.xml" );
IPingHolder service = (IPingHolder) registry.getService(
"playground.PingHolderSetter", IPingHolder.class );
service.getPing().ping();
assertSame( IPing.class, ObjectProviderMock.propertyType );
}
}
playground.Ping.java:
package playground;
public class Ping implements IPing {
public Ping() {
super();
}
public String ping() {
return "ping..";
}
}
playground.PingHolder.java:
package playground;
import playground.IPing;
public class PingHolder implements IPingHolder {
private IPing ping;
/**

public PingHolder() {
super();
}
/**

*/
public PingHolder( IPing ping ) {
super();
this.ping = ping;
}
/**

*/
public IPing getPing() {
return ping;
}
/**
* @param ping The ping to set.
*/
public void setPing( IPing ping ) {
this.ping = ping;
}
}

Betreff: Re: ObjectProvider.provideObject(..) question/problem
Stefan,
First of all, sorry about the long delay! I don't think the parameter
value always is Object.class, so this is possibly a bug in HiveMind.
Could you please provide more details about where you see this
behaviour? Maybe even A JUnit test :-)
