[Groovy] Class FunctionSensorAdapter

java.lang.Object
  brooklyn.event.adapter.AbstractSensorAdapter
      brooklyn.event.adapter.FunctionSensorAdapter

@Deprecated
class FunctionSensorAdapter
extends AbstractSensorAdapter

Entry point for wiring up arbitrary functions to be used as the source for sensors.

Example usage:

 def fnSensorAdaptor = sensorRegistry.register(new FunctionSensorAdapter(&myFunction));
   fnSensorAdaptor.poll(MY_BROOKLYN_RAW_DATA_ATTRIBUTE)
   fnSensorAdaptor.then({ MyStruct.parse(it) ).with {
       then({ it.field1 }).poll(MY_BROOKLYN_ATTRIBUTE_1)
       then({ it.field2 }).poll(MY_BROOKLYN_ATTRIBUTE_2)
   }
   //or, field1 access can also be written:
   fnSensorAdaptor.poll(MY_BROOKLYN_ATTRIBUTE_1, { MyStruct.parse(it).field1 } )
 }
