Description

The IShields interface provides members that are used for refining Directions, by allow the specification of Shield information, such as the type and number of a highway.  Unlike the network source level directions information, such as IStreetNameFields , only one set of Shields information can be specified for a network dataset.  Shield information is not required for Directions generation.

If shield data exists for a network source, it can be in one of two forms:

• All shield information is stored within a single field, with values such as T-C HWY 1 or US HWY 10
• The Type and Number are stored in separate fields
