Interface AzAttributeResolver

public interface AzAttributeResolver

AzAttributeResolver provides runtime resolution of attributes.

This is used to obtain attribute values which are not available in the corresponding AzAttributes collection. Implementations may obtain the attribute values from arbitrary sources, including calculation or from remote servers. Since an AzAttributeResolver may be called frequently during time- sensitive operations, caching and other performance-enhancing techniques should be used by the implementation.
