sedb.gcev - Package: sedb

Identifier of current event

Syntax

evid = gcev

Description

evid = gcev returns the identifier of the event associated with the current operation. If the current operation does not change the event calendar, evid is an empty string. A change to the event calendar can be the scheduling, execution, or cancelation of an event.

Examples

View the event associated with the current operation:

Begin a debugger session for a particular model. At the MATLAB command prompt, enter:
```
sedebug('sedemo_async_stateflow_ent')
```

Proceed in the simulation. At the sedebug>> prompt, enter:

tbreak 1
cont

The output ends with the current operation, which is the execution of the event with identifier ev6:

%==============================================================================%
Executing ServiceCompletion Event (ev6)               Time = 1.000000000000000
: Entity = en2                                        Priority = 500
: Block  = Asynchronous Execution/Single Server

View information about the event associated with the current operation:

evid = gcev
evdetails = evinfo(evid)

The output shows the same identifier, ev6, in the workspace variable, evid, and the ID field of the structure, evdetails:

evid =

ev6


evdetails = 

           ID: 'ev6'
    EventType: 'ServiceCompletion'
    EventTime: 1
     Priority: '500'
       Entity: 'en2'
        Block: 'sedemo_async_stateflow_ent/Asynchronous Execution/Single Server'

Proceed further in the simulation:

step

The output is:

    %..........................................................................%
    Scheduling EntityRequest Event (ev7)
    : EventTime = 1.000000000000000 (Now)
    : Priority  = SYS2
    : Block     = Asynchronous Execution/Single Server

View information about the event associated with the current operation. This event is the entity request event the simulation is scheduling, not the service completion event whose execution causes the scheduling of the entity request event.
```
evid_next = gcev
evdetails_next = evinfo(evid_next)
```
The output refers to the event identifier, ev7:
```
evid_next =

ev7


evdetails_next = 

           ID: 'ev7'
    EventType: 'EntityRequest'
    EventTime: 1
     Priority: 'SYS2'
       Entity: ''
        Block: 'sedemo_async_stateflow_ent/Asynchronous Execution/Single Server'
```
End the debugger session. At the sedebug>> prompt, enter:
```
sedb.quit
```
