Flow security model enter rule

enter {sid : <Sid>, state : <State>}

It switches the finite-state machine associated with the resource that has the security ID sid to the specified state.

It returns the "allowed" result if the finite-state machine was switched to the specified state.

It returns the "denied" result in the following cases:

The transition to the specified state from the current state is not permitted by the configuration of the finite-state machine.
The resource with the security ID sid is not associated with a finite-state machine of the Flow security model object being used.
Security ID sid is out of the permissible range.

Example:

/* Any client in the solution will be allowed to query

* a server of the Server class if the finite-state machine

* associated with this server will be switched

to the "started" state when initiating the query. Otherwise

* any client in the solution will be denied to query

* a server of the Server class. */

request dst=Server {

service_flow.enter {sid : dst_sid, state : "started"}
