SharePoint SPClaimProvider details/usage

Question

I have to implement my own SPClaimProvider for PeoplePicker. There are some methods to override. Problem: I can't figure out some methods/parameters usage. All of these methods are claims specific.

Examples:

• method FillClaimValueTypes. What is claim value type? What doest it mean?
• method FillSearch, parameters hierarchyNodeID, searchTree - what this all is about? How can I use this?

Got ideas?

Answer 1

Have you had a chance to check out these articles? How to create a claims provider Claims Walkthrough: Writing Claims Providers for SharePoint 2010

for FillClaimValueTypes - just a list that must match order of FillClaimTypes as well. This is what your provider adds in terms of claims. The type is a namespace, ie. such as http://mystuff/claims/myspecialclaim - it's a distinguishing identifier.
