    • getAllDeclaredFields

      public static Set<Field> getAllDeclaredFields(Class<?> _class, String... _fieldsToIgnore)
      Extract all Fields found in the given class recursively. This means, all Fields are retrieved, even fields which only exists in superclasses.

      NOTE: Accessibility of Fields returned in the Set have not been changed (setAccessable(true) is NOT called explicitly)!
      Parameter:
      _class - class to analyze
      _fieldsToIgnore - fields to skip
      Gibt zurück:
      null if _class was null, Set otherwise

    • getAllDeclaredStaticFields

      public static Set<Field> getAllDeclaredStaticFields(Class<?> _class, String... _fieldsToIgnore)
      Extract all Fields which are static and do not match any of the given ignore names.
      Parameter:
      _class - class to analyze
      _fieldsToIgnore - fields to skip
      Gibt zurück:
      null if _class was null, Set otherwise

    • getAllDeclaredNonStaticFields

      public static Set<Field> getAllDeclaredNonStaticFields(Class<?> _class, String... _fieldsToIgnore)
      Extract all Fields which are not static and do not match any of the given ignore names.
      Parameter:
      _class - class to analyze
      _fieldsToIgnore - fields to skip
      Gibt zurück:
      null if _class was null, Set otherwise

      @SafeVarargs public static Set<Field> getAllDeclaredFieldsAnnotatedWithAny(Class<?> _class, Class<? extends Annotation>... _annotations)
      Extract all Fields with any of the given annotations found in the given class recursively. This means, all Fields are retrieved, even fields which only exists in superclasses.

      NOTE: Accessibility of Fields returned in the Set have not been changed (setAccessable(true) is NOT called explicitly)!
      Parameter:
      _class - class to analyze

      Typparameter:
      T - type
      Parameter:
      _clz - class to instantiate
      Gibt zurück:
      new instance or null
