Java - Class type from inside static initialization block
- by DutrowLLC
Is it possible to get the class type from inside the static initialization block?
This is a simplified version of what I currently have::
class Person extends SuperClass {
String firstName;
static{
// This function is on the "SuperClass":
// I'd for this function to be able to get "Person.class" without me
// having to explicitly type it in but "this.class" does not work in
// a static context.
doSomeReflectionStuff(Person.class); // IN "SuperClass"
}
}
This is closer to what I am doing, which is to initialize a data structure that holds information about the object and its annotations, etc... Perhaps I am using the wrong pattern?
public abstract SuperClass{
static void doSomeReflectionStuff( Class<?> classType, List<FieldData> fieldDataList ){
Field[] fields = classType.getDeclaredFields();
for( Field field : fields ){
// Initialize fieldDataList
}
}
}
public abstract class Person {
@SomeAnnotation
String firstName;
// Holds information on each of the fields, I used a Map<String, FieldData>
// in my actual implementation to map strings to the field information, but that
// seemed a little wordy for this example
static List<FieldData> fieldDataList = new List<FieldData>();
static{
// Again, it seems dangerous to have to type in the "Person.class"
// (or Address.class, PhoneNumber.class, etc...) every time.
// Ideally, I'd liken to eliminate all this code from the Sub class
// since now I have to copy and paste it into each Sub class.
doSomeReflectionStuff(Person.class, fieldDataList);
}
}
