Class AnnotationAndReflectionHelper

  • public class AnnotationAndReflectionHelper
extends Object
    User: Stephan Bösebeck Date: 07.03.13 Time: 11:10

    This class will encapsulate all calls to the reflection API. Specially getting all the annotations from entities is done here. For performance increase (and because the structure of the code usually does not change during runtime) those results are being cached.

    this class is ThreadSafe!
