brooklyn.event.adapter
[Groovy] Class AbstractSensorEvaluationContext

java.lang.Object
  brooklyn.event.adapter.AbstractSensorEvaluationContext

abstract class AbstractSensorEvaluationContext

provides fields and methods that are brought into scope when executing closures submitted by an entity developer for evaluating a sensor; fields can be made explicit, to be shared among multiple sensors; and specific per-sensor evaluation properties can be passed as "extraProperties" which exist only for that evaluation context duration

Field Summary
static java.lang.Object UNSET

may throw exception, or return UNSET to not change
static Logger log

 
Property Summary
java.lang.Exception error

exception returned by call, or null if no error
java.util.Map extraProperties

 
Method Summary
java.lang.Object evaluate(Entity entity, Sensor sensor, groovy.lang.Closure c)

evaluate the closure in the (resolve) context of the implementing class (e.g. a specific HTTP response), so that methods and variables in the class are available to the closure; entity and sensor available for inspection but can be null during testing; default values are specified by the response context; return value is normally adapted by the caller (e.g. the sensor adapter) to suit the sensor; this method (and thus the closure) may return UNSET to indicate the adapter should not update the sensor
java.lang.Object evaluate(java.util.Map properties = [:], groovy.lang.Closure c)

protected java.lang.Object getDefaultValue()

java.lang.Object propertyMissing(java.lang.String name)
