        AttributeDef

Known Subclasses:

is the base class for all attribute definitions.

See above.

The data attribute names have all an underscore added to avoid name clashes -- structures should have about the same attributes and may want to have managed attributes called name or description.

When constructing AttributeDefs, you should only use keyword arguments, except for name (the first argument).

Note that an AttributeDef might be embedded by many instances. So, you must *never* store any instance data in an AttributeDef (unless it's really a singleton, of course).

Instance Methods

__init__(self, name, default=None, description='Undocumented', copyable=False, aliases=None, callbacks=None, before=None)
x.__init__(...) initializes x; see help(type(x)) for signature source code

doCallbacks(self, instance, value)
should be called after feedObject has done its work.

source code

feed(self, ctx, instance, value)

source code

feedObject(self, instance, value)

source code

getCopy(self, instance, newParent, ctx)

source code

iterParentMethods(self)
returns an iterator over (name, method) pairs that should be inserted in the parent class.
