  public static final boolean isActualClass(Class<?> type)
- isEnum
  
  public static boolean isEnum(Class<?> c)
  
  Utility method fixing the WRONGLY implemented Class.isEnum().
  Their description is weird ("if this class was declared as an enum in the source code") and the implemented behavior is dangerous and useless to identify all classes of instances that are enums.
  For enum anonymous inner class instances (writing { ... } behind an enum constant), Class.isEnum() returns false on the generated type. That is a bug since the type is still an enum, a sub class of Enum. So the correct way of testing a class for being an enum is using java.lang.Enum.class.isAssignableFrom(...). This method does that.
  
  Parameters:
  
  c - the Class to be tested.
  
  Returns:
  
  whether the passed Class is a sub class of Enum, i.e. an enum.

  public static <T> Class<T> validateIsEnum(Class<T> type)
- iterateDeclaredFieldsUpwards
  
  public static final <L extends Consumer<Field>> L iterateDeclaredFieldsUpwards(Class<?> startingClass, L logic)
  
  Alias for iterateDeclaredFieldsUpwards(startingClass, Object.class, logic).
  
  Type Parameters:
  
  L - The logic's contextual type.
  
  Parameters:
  
  startingClass - the class whose fields shall be iterated.
  
  logic - the Consumer to be executed on each field.
  
  Returns:
  
  the passed logic.
- iterateDeclaredFieldsUpwards
  
  public static final <L extends Consumer<Field>> L iterateDeclaredFieldsUpwards(Class<?> startingClass, Class<?> boundingClass, L logic)
  
  Iterates over every declared field of all classes upwards starting at startingClass until class boundingClass is reached and executes the passed Consumer on it.
  The declared fields of each class are iterated in reverse order (from index Class.getDeclaredFields().length - 1 to index 0 ).
  This method is useful to maintain the natural declaration order of the fields, iterating from the last declared field of the lowest class (the passed class itself) to the first declared field of the highest class declaring a field.
  
  Type Parameters:
  
  L - The logic's contextual type.
  
  Parameters:
  
  startingClass - the class whose fields shall be iterated.
  
  boundingClass - the class in the hierarchy at which to stop iterating, exclusive bound.
  
  logic - the Consumer to be executed on each field.
  
  Returns:
  
  the passed logic.

  Throws:
  
  IllegalAccessRuntimeException
- resolveType
  
  public static final Class<?> resolveType(String typeName, ClassLoader classLoader) throws LinkageError, ExceptionInInitializerError, ClassNotFoundException
  
  Resolves the passed type name to a runtime type (instance of type Class). In contrary to JDK's type resolving mechanisms, this method resolves primitive type names, as well.
  Note on naming:
  1.) Looking up a runtime type instance for a type name string is best described as "resolving" the type.
  2.) The things that are resolved are TYPES (classes, interfaces, arrays and in later Java versions enums and annotations), not just classes. That the java inventors seemingly didn't understand their own type system and just called everything "Class" on the API-level,* even interfaces, is just an error that should be repeated as less as possible.
  
  Parameters:
  
  typeName - the type name to be resolved, primitive name or full qualified type name.
  
  classLoader - class loader from which the class must be loaded
  
  Returns:
  
  the resolved type instance (of type Class)
  
  Throws:
  
  LinkageError - see Class.forName(String)
  
  ExceptionInInitializerError - see Class.forName(String)
  
  ClassNotFoundException - see Class.forName(String)
- resolveTypeForName
  
  public static final Class<?> resolveTypeForName(String typeName) throws LinkageError, ExceptionInInitializerError, ClassNotFoundException
  
  Uses Class.forName(String) which uses the calling class's ClassLoader.
  
  Parameters:
  
  typeName - the type name to be resolved, primitive name or full qualified type name.
  
  Returns:
  
  the resolved type instance (of type Class)
  
  Throws:
  
  LinkageError - see Class.forName(String)
  
  ExceptionInInitializerError - see Class.forName(String)
  
  ClassNotFoundException - see Class.forName(String)
- tryResolveType
  
  public static final Class<?> tryResolveType(String typeName, ClassLoader classLoader)
  
  Calls resolveType(String, ClassLoader), but suppresses any ClassNotFoundException and returns null instead. This is useful if the passed class name is only potentially resolvable at runtime and is still valid if not. Example: resolving a old type dictionary as far as possible and marking the not resolvable types as unresolvable.
  
  Parameters:
  
  typeName - the type name to be resolved, primitive name or full qualified type name.
  
  classLoader - class loader from which the class must be loaded
  
  Returns:
  
  the Class instance representing the passed class name or null if unresolevable.
- iterativeResolveType
  
  public static final Class<?> iterativeResolveType(ClassLoader classLoader, String... typeNames) throws ClassNotFoundException
  
  Alias for tryIterativeResolveType(ClassLoader, String...) with the following difference:
  If none of the passed typeNames can be resolved, a ClassNotFoundException listing all passed typeNames is thrown.
  
  Parameters:
  
  classLoader - class loader from which the class must be loaded
  
  typeNames - the full qualified type names to be attempted to be resolved one by one.
  
  Returns:
  
  the first successfully resolved Class instance.
  
  Throws:
  
  ClassNotFoundException - if none of the passed typeNames could have been resolved.
  
  See Also:
  
  tryIterativeResolveType(ClassLoader, String...)
- tryIterativeResolveType
  
  public static final Class<?> tryIterativeResolveType(ClassLoader classLoader, String... typeNames)
  
  This methods attempts to resolve the passed typeNames to Class instances using resolveType(String, ClassLoader) one by one. The Class instance of the first successful attempt is returned. If none of the passed typeNames can be resolved, null is returned. See iterativeResolveType(ClassLoader, String...) for an exception-throwing version.
  Note:
  While it is generally a bad idea to just use a trial and error approach until something works, a logic like this is required to resolve types whose packages changes accross different versions of a library. If the different full qualified class names are known, they can be used in an iterative attempt to resolve the class, hence avoiding hard dependencies to certain library versions in the using code by moving type names from imports at compile time to dynamic class resolving at runtime.
  However, this approach has its limits, of course. If too much changes (field names, method names, parameters, behavior) the dynamic strategy results in chaos as the compiler gets more and more circumvented and more and more source code is transformed into contextless plain strings.
  Therefore, when in doubt, it is preferable to stick to the general notion of this method being a "bad idea" and finding a more reliable solution.
  
  Parameters:
  
  classLoader - class loader from which the class must be loaded
  
  typeNames - the full qualified type names to be attempted to be resolved one by one.
  
  Returns:
  
  the first successfully resolved Class instance or null
