Hi All,

How can i convert string to thing name or thing template name to access entity services within eclipse?

How can i define a thing template name as like Base Types? 

Thanks.

Hi @Sathishkumar_C,

In general, entity names are just a String from a back-end perspective. To reach Thing and its characteristics, you can do the following:

String entityName = "MyThing";

// there are various ...Utilities classes that will help to find a proper entity
Thing myThing = ThingUtilities.findThing(entityName);

// OOTB service
ThingProperty myProperty = myThing.getProperty("MyProperty");
 
// custom service
ValueCollection inputParams = new ValueCollection();
inputParams.SetStringValue("InputParam1", "In");
inputParams.SetNumberValue("InputParam2", 5);
InfoTable output = myThing.processServiceRequest("CustomService", inputParams);

Hope that it answers your question. If yes, please mark my answer as a correct one for other for the reference.

BR,

Jakub.

Thanks for your reply.

I want to return "GetImplementingThingWithData" for a particular thing template. How can i achieve this.?

Hi,

I posted above a general rule, so you can apply it to any use case.

Answering directly, you can do the following (please keep in mind, that I implemented this code on Extension SDK 8.0.0, on other SDK version it can be slightly different):

ThingTemplate genericTemplate = (ThingTemplate) EntityUtilities.findEntity(entityName, ThingworxRelationshipTypes.ThingTemplate);
InfoTable implementingThings = genericTemplate.GetImplementingThings();
		
implementingThings.getRows().stream().forEach(row -> {
	Thing t = ThingUtilities.findThing(row.getStringValue("name"));
	_logger.warn("Thing based on GenericThing: " + t.getName());
});

Please also be aware, that the above code is just a snippet, example.

If you consider my answer correct, please mark it as such, so other can refer.

BR,

Jakub.
