Thank you Andreas. It is named "StoryContext" and is used for compile-time
properties and runtime properties..
It has a storage for properties and supports to bundle these properties
into predefined Java business objects. I am not sure if I will use that
bundle solution or just plain keys with prefixes and their values.
The simple solution which acts like a re-settable property registry would
then look something like the code below. I think I would like to use that
for runtime properties. Handling compile-time properties could be solved
maybe with Apache Commons Configuration or something like that.
import java.util.HashMap;
import java.util.Map;
/**
* Manages properties which can be set and get at runtime. </br>
* Internally ThreadLocal is used so that each Thread has its own instance.
*/
public class DynamicProperties {
private static final class ContextLocal extends
ThreadLocal<DynamicProperties> {
@Override
protected DynamicProperties initialValue() {
return new DynamicProperties();
}
}
private static final ThreadLocal<DynamicProperties> context = new
ContextLocal();
private Map<String, String> properties = new HashMap<String, String>();
public static DynamicProperties instance() {
return context.get();
}
private DynamicProperties self() {
return instance();
}
public void reset() {
context.set(new DynamicProperties());
}
public void put(String key, String value) {
self().properties.put(key, value);
}
public String get(String key) {
return self().properties.get(key);
}
}
