Class Hierarchy

• __builtin__.object: The most base type
  • harold.prog.namespace.ambiguous_member.AmbiguousMember: An implementation artifact to manage ambiguous members.
    • harold.prog.namespace.ambiguous_member._TransitionnalAmbiguousMember
  • harold.callabletools.CallableWrapper: Base class for wrapping callables.
    • harold.prog.abstract.member.method: An abstract method.
  • types.instancemethod: instancemethod(function, instance, class)
  • __builtin__.property: property(fget=None, fset=None, fdel=None, doc=None) -> property attribute fget is a function to be used for getting an attribute value, and likewise fset is a function for setting, and fdel a function for del'ing, an attribute.

    • harold.prog.abstract.abstractable_class.AbstractableClass: A metaclass with checks about abstract members.
      • harold.prog.HaroldClass: A metaclass providing functionnalities of all harold programming tools.
        • harold.prog.HaroldClassWithAutoProperties: A metaclass providing functionnalities of all harold programming tools, and automatically adding properties when the class has method named according to the following pattern:
    • harold.prog._deftracker.DefinitionsTracker: A class keeping track, in its _definitions attribute, of the superclasses defining each of its inherited methods.
      • harold.prog.interface.interface_class.InterfaceClass: A class with contractual interface.
        • harold.prog.HaroldClass: A metaclass providing functionnalities of all harold programming tools.

  • harold.callabletools._Unbounded
  • harold.prog.namespace._intervals_tree.IntervalsTree:  
• exceptions.Exception: Common base class for all exceptions.
  • harold.prog.abstract.exceptions.AbstractMemberAccessException: Raised whenever an abstract member is accessed.
    • harold.prog.abstract.exceptions.AbstractAttributeException: Raised whenever an abstract attribute is accessed (get or set).
    • harold.prog.abstract.exceptions.AbstractMethodInvocationException: Raised whenever an abstract method is invoked.
  • harold.prog.namespace.exceptions.AmbiguousMemberException: Raised whenever an explicitly ambiguous member is accessed in a context where no namespace has been set for it.
  • harold.prog.namespace.exceptions.ConflictingNamespacesException: Raised by AmbiguousMember whenever a context already having an assigned namespace is assigned another context
  • harold.prog.abstract.exceptions.ImplementationException: Raised whenever an abstract class is assigned an inconsistent default implementation.
  • harold.prog.namespace.exceptions.NoDefinitionInNamespaceException: Raised by AmbiguousMember whenever an assigned namespace does not define this ambiguous member.
  • harold.prog.namespace.exceptions.UnrecognizedContextException: Raised by AmbiguousMember whenever an abject used as a context is not recognize.
  • exceptions.Warning: Base class for warning categories.
    • harold.prog.abstract.exceptions.AbstractClassInstantiationWarning: Issued whenever an abstract class without any default implementation is instantiated.
    • harold.prog.abstract.exceptions.AbstractOverridesConcreteWarning: Issued whenever an abstract member overrides a concrete one, which is usually the consequence of an inappropriate order in the superclasses.
    • harold.prog.namespace.exceptions.AmbiguousClassWarning: Issued whenever a harold.prog.namespace.nsaware_class.NsAwareClass declares ambiguous members implicitely.
    • harold.prog.namespace.exceptions.AmbiguousMemberWarning: Issued whenever an implicitly (i.e.
