TypedMappers

A TypedMapper is a helpful, extrememly lightweight type-safe wrapper class around a NetQuarry Mapper object.

You typically use a TypedMapper as a helper class in an extension. You can create a TypedMapper and attach it to the sender (IMapper) of the event or you can use the TypedMapper derivative to create a new mapper – either for the purpose of creating a new row or reading/updating an existing one. Connecting a TypedMapper via one of the constructors or TypedMapper.Attach is very inexpensive and generally a safer way to work with a mapper.

Picklists

We”ve spent a bunch of time solving the problem of vocabulary lists for a database application. A vocabulary list is one of those tables that have a key (typically an integer or a GUID) and some text. The “key” (primary key in DBMS-speak) is referenced by a column in a more important table. Most of the time, the end-user selects this key by choosing an item via a drop down list box that has some human readable text and the application stores the item’s “key” into the database. We call the object that solves this problem a Picklist.
