Class Resolver

I am can resolve backward named references in a block of code.

Objects created by a block of code that are inserted into a dictionary I store a reference to may later indicate a backreference to one of those objects by creating a 'reference.Reference', specifying the key to be looked up later.

Instantiate me with a lookup table populated with references, then resolve a graph of objects using that table.

Method Summary
	`__init__(self, lookup)` Create a resolver.
	`res(self, obj)` Traverse a single object's graph and resolve it and its subobjects.
	`resdict(self, dict)` Resolve a dictionary; private use
	`resinst(self, inst)` Resolve an instance; private use
	`reslist(self, lst)` Resolve a list; private use
	`resolve(self, reflist)` Resolve a list of references.

Method Details

Create a resolver.

Parameters:: lookup - is an object which responds to the __getitem__ interface and contains all the keys which can be referred to by the References in the 'reflist' argument to my resolve method.
