I understand you are trying to serialize a Sadly, Cepheus CEP does not handle nesting of types (it would be nice to be able to just define the For reference, others projects having the same problem with serializing a JTS What is unclear for me, is why you would like to serialize the whole If this is because you simplified the statement to demonstrate the problem compared to the original Geofencing example, maybe a solution in the mean time would be transpose each of the properties from the {

The reason why I am trying to serialize the whole Tracker as "text" (could be even java.util.Map) is because Cepheus is part of a much more complex architecture of an IoT application where I have multiples types of context entities and each one generates Alerts. Then I am working on a integration component that takes each Alert and for example send it to a third party system (could be fire an Email, etc). Since each context entity have a different schema (entity type) I want to define something like an "Envelope" entity type for all the alerts in order to get a common set of attributes, most of them for internal use. That's the reason why I am putting the whole Tracker info into a single attribute in my example. Just to clarify, I am not serializing Tracker as "text", in fact I am using type "java.util.Map". I put it as "text" in the issue just to make it simple. In the meantime I can "flat" the whole context as you suggests at the cost of losing the "common" envelope. Thank you and I hope you can incorporate this issue as a future bug fixes. Best Regards. |
I am experiencing a problem when I define geofencing rules using an attribute of type geo: point in an Event-In and then try to save this attribute together with others within another attribute in the Event-Out.
This is a concrete example of my configuration based on the "Tracker" example of the Cepheus doc. I also simplified the statements and added some extra parameters in configuration. BTW, I am using Docker Containers:
{ "service": "test", "servicePath": "/tracker", "host": "http://172.17.0.1:8080", "reset": true, "statements": [ "INSERT INTO Alert SELECT * FROM Tracker t WHERE NOT polygon({point(0, 0), point(0,50), point(50,50), point(50, 0), point(0, 0)}).contains(t.location)" ], "in": [ { "id": ".*", "type": "Tracker", "isPattern": true, "attributes": [ { "name": "time", "type": "date" }, { "name": "location", "type": "geo:point" } ], "providers": [ { "url": "http://172.17.0.1:1026", "service": "test", "servicePath": "/tracker" } ] } ], "out":[ { "id":"Fence1", "type":"Alert", "attributes":[ { "name":"time", "type":"date" }, { "name":"location", "type":"geo:point" }, { "name":"inside", "type":"boolean" }, { "name":"nested", "type":"text" } ], "brokers": [ { "url": "http://172.17.0.1:1026", "serviceName": "test", "servicePath": "/tracker", "authToken": null } ] } ] }Then this is the Tracker1 context entity that I just created using Orion NGSI v2 API.
{ "id": "Tracker1", "type": "Tracker", "time": { "value": "2015-10-26T22:47:09Z", "type": "date" }, "location": { "value": "45.1234, 1.6543", "type": "geo:point" } }Then if you make an UPDATE context like the following everything works fine and the Alarm is raised.
curl -X POST \ 'http://localhost:1026/v2/entities/Tracker1/attrs?type=Tracker' \ -H 'Content-Type: application/json' \ -H 'Fiware-Service: test' \ -H 'Fiware-ServicePath: /tracker' \ -d '{ "time": { "value": "2015-10-26T22:47:09Z", "type": "date" }, "location": { "value": "60.1234, 1.6543", "type": "geo:point" } }'The problem is what happens if for some reason you want to generate a new attribute, for example an attribute called "nested" and then populate it with the entire Event In context information.
This is my configuration example in order to do so:
{ "service": "test", "servicePath": "/tracker", "host": "http://172.17.0.1:8080", "reset": true, "statements": [ "INSERT INTO Alert SELECT *, t as nested FROM Tracker t WHERE NOT polygon({point(0, 0), point(0,50), point(50,50), point(50, 0), point(0, 0)}).contains(t.location)" ], "in": [ { "id": ".*", "type": "Tracker", "isPattern": true, "attributes": [ { "name": "time", "type": "date" }, { "name": "location", "type": "geo:point" } ], "providers": [ { "url": "http://172.17.0.1:1026", "service": "test", "servicePath": "/tracker" } ] } ], "out":[ { "id":"Fence1", "type":"Alert", "attributes":[ { "name":"time", "type":"date" }, { "name":"location", "type":"geo:point" }, { "name":"inside", "type":"boolean" }, { "name":"nested", "type":"text" } ], "brokers": [ { "url": "http://172.17.0.1:1026", "serviceName": "test", "servicePath": "/tracker", "authToken": null } ] } ] }Cepheus CEP accept the configuration files but when I make an UPDATE context request I get the following error in Cepheus CEP logs:
