                                            MixinAttribute

An attribute defining a mixin.

This currently is only offered on tables, though in principle we could have it anywhere now, but we'd want some compatibility checking then.

This is never copyable since this would meaning playing the same stuff into an object twice.

This means trouble for magic scripts (in particular processLate); e.g., if you copy a table mixing in products, the data element for that table will not receive the product table. Goes to show the whole product mess is ugly and needs a good idea.

Instance Methods

__init__(self, **kwargs)
x.__init__(...) initializes x; see help(type(x)) for signature

source code

feed(self, ctx, instance, mixinRef, fillers={})
feeds the immediate elements and schedules the rest of actions to be taken in time. source code

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