ViewCapDataWindowAccess | Describes that we need random access into a data window by index. |
ViewCapPriorEventAccess | Describes that we need access to prior events (result events published by views), for use by the "prior" expression function. |

ViewEnum | Enum for all build-in views. |
ViewFieldEnum | Enumerates the valid values for each view's public fields. |
Exception Summary | |
---|---|
ViewAttachException | Thrown to indicate a validation error in staggered views. |
