Detailed Description

This class assigns and gets the ProductResolverIndex associated with a type, module label, instance, and process. The ProductResolverIndex is used to tell the Principal where to store a ProductResolver and how to find it quickly.

One can also look up the same ProductResolverIndex's using the type or base type of an element in a container in the product (if the product is a container). In this case the KindOfType argument to the Principal::getByLabel function is ELEMENT_TYPE, whereas normally it is PRODUCT_TYPE.

There are also special ProductResolverIndex's generated where the process name is empty. These indexes refer to a special ProductResolvers that search for a matching product from the most recent process that has a matching type, label and instance. There is ProductResolverIndex generated for each type/label/instance combination which has at least one entry in the tables in this class. Both PRODUCT_TYPEs and ELEMENT_TYPEs get these special ProductResolvers.

The ProductResolverIndex for a particular product will not change during a process after the ProductRegistry has been frozen. Nor will any of the other member data of this class. Multiple threads can access it concurrently without problems. The ProductResolverIndexes can be safely cached in InputTags and possibly other places, because they never change within a process. The ProductResolverIndex for a particular product is not intended to be persistent and will be different in different processes.

The ProductResolverIndex is used to order the placement of the ProductResolvers in the Principal that are either present in the input or produced in the current process. Be aware that there are other ProductResolvers for products that come after ProductResolvers placed by this class. For example, the placement of dropped products is not handled by this class, instead by the ProductRegistry. The reason for this distinction is that those other ProductResolvers can change and be added as a process runs. The content of this class never changes after the ProductRegistry is frozen.
