Interface IEntityClass

public interface IEntityClass

Entities within an entity class are grouped into Device objects based on the IEntityClass, and the key fields specified by the entity class. A set of entities are considered to be the same device if and only if they belong to the same entity class and they match on all key fields for that entity class. A field is effectively wildcarded by not including it in the list of key fields returned by IEntityClassifierService and/or IEntityClass. Note that if you're not using static objects, you'll need to override Object.equals(Object) and Object.hashCode().
