org.apache.felix.scr.impl.helper.MethodResult
The MethodResult conveys the return value of one of the activate, modify, and deactivate methods.
Note that the method returning null or being defined as void is not the same thing. If the method returns null an instance of this class is returned whose {@link #getResult()} method returns null. If the method isdefined as void the special instance {@link #VOID} is returned.
