10.20 ConnectionStateEnum

The ConnectionStateEnum provides information about the current state of the Connection, as determined by the ConnectionManager. See 10.19 for a description of the ConnectionState. The ConnectionStateEnum values are formally defined in Table 166.

ConnectionNotEstablished can result from any of the following:

ConnectionManager has not yet established the Connection;

ConnectionManager has successfully removed the Connection;

ConnectionManager detected that one or both ConnectionEndpoints have been removed (e.g., due to ConnectionEndpoint auto-cleanup or AutomationComponent power-cycle).

ConnectionStateEnum combines the Status of all ConnectionEndpoints participating in a Connection (see 10.20).

For Connection types bidirectional, unidirectional and unidirectional with heartbeat, the value is calculated according to Figure 58.

For Connection types autonomous publisher and autonomous subscriber, the value is calculated according to Figure 59.

The ConnectionStateEnum representation in the AddressSpace is formally defined in Table 167.
