Hi JB,
yes but until i created one there is nothing to iterate/find.
However, i think did not explain my problem very well so i try to explain what
i want to do.
Maybe i took the wrong approach to solve my problem. So lets consider the
following classes:
@Component(
service = MyInterface.class,
configurationPid = "my.factory.prefix.A"
configurationPolicy=ConfigurationPolicy.REQUIRE,
property = {
"prop1=A",
"prop2=foo"})
public class MyComponentA implements MyInterface {
@Modified
public void modified(ComponentContext componentContext){
//change something in this component
}
public void dostuff(){}
}
@Component(
service = MyInterface.class,
configurationPid = "my.factory.prefix.B"
configurationPolicy=ConfigurationPolicy.REQUIRE,
property = {
"prop1=B",
"prop2=bar"})
public class MyComponentB implements MyInterface {
@Modified
public void modified(ComponentContext componentContext){
//change something in this component
}
public void dostuff(){}
}
public class MyFancyManager implements MyFancyInterface {
public List<String> listAvailableComponentFactories(){
// how do i "iterate" over all factories without that i
// have already created one? I don't know which
// factories are present in advance or bundles
// dynamically add new components factories
}
public void changeConfig(String filter, Map<String, String> config){
//
configManager.listConfig(filter).stream().filter().any().update(config)
}
public void createSomething(String type, Map<String, String> config){
Configuration cfg =
configurationAdmin.createFactoryConfiguration("my.factory.prefix."+type, null);
Hashtable<String, Object> prop = new Hashtable<>();
prop.put("prop3", "foobar");
cfg.update(testProp);
}
}
And now i like to create some services from type A, some from type B and then i
like to change configurations of existing services.
best regards,
Matthias

Hi Mathias,
The factoryPid doesn't change: it's com.foo.bar.
The configurationPid is based on the factory PID: com.foo.bar.xxxx (in
config:list).
So you can find "your" configurations based on your factoryPid. You can
list all configuration for a given factoryPid:
config:list "(factoryPid=com.foo.bar)"

JB
