brooklyn.event.adapter
[Groovy] Class SensorRegistry

java.lang.Object
  brooklyn.event.adapter.SensorRegistry

@Deprecated
@SuppressWarnings("deprecation")
class SensorRegistry

This class manages the periodic polling of a set of sensors, to update the attribute values of a particular Entity. When a "sensor adapter" is registered, it is immediately activated which will cause it to begin polling. When the registry is closed (e.g. on entity-stop), all registered sensor-adapters will automatically be de-activated. It is strongly recommended to not modify a sensor-adapter while concurrently registering it (e.g. adding additional sensors to it in a separate thread).

deprecated:
since 0.5; see brooklyn.event.feed.*

Property Summary
boolean activated

EntityLocal entity

static Logger log

java.util.Map properties

@deprecated in 0.4. use new SensorAdapter model.
 
Constructor Summary
SensorRegistry(EntityLocal entity, java.util.Map properties = [:])

 
Method Summary
void activateAdapters()

@deprecated activated automatically, as soon as constructed.
void addActivationLifecycleListeners(java.lang.Runnable onUp, java.lang.Runnable onDown)

TODO If called in separate thread concurrently with activateAdapters or deactivateAdapters/close, then listener could be called twice.

void addSensor(AttributeSensor sensor, ValueProvider provider)

@deprecated in 0.4. use new SensorAdapter model.
void addSensor(AttributeSensor sensor, ValueProvider provider, long period)

@deprecated in 0.4. use new SensorAdapter model.
void close()

void deactivateAdapters()

java.util.concurrent.ScheduledExecutorService getExec()

java.lang.Object register(java.lang.Object adapter)

records an adapter that has been created for use with this registry; implementations may return a compatible adapter if one is already registered
void removeSensor(AttributeSensor sensor)

@deprecated in 0.4. use new SensorAdapter model.

deprecated:
activated automatically, as soon as constructed.

addActivationLifecycleListeners

void addActivationLifecycleListeners(java.lang.Runnable onUp, java.lang.Runnable onDown)
TODO If called in separate thread concurrently with activateAdapters or deactivateAdapters/close, then listener could be called twice. Recommend not adding activation listeners like that!

deprecated:
in 0.4. use new SensorAdapter model.

addSensor

@Deprecated
void addSensor(AttributeSensor sensor, ValueProvider provider, long period)
deprecated:

close

void close()

deactivateAdapters

void deactivateAdapters()

getExec

java.util.concurrent.ScheduledExecutorService getExec()

register

java.lang.Object register(java.lang.Object adapter)
records an adapter that has been created for use with this registry; implementations may return a compatible adapter if one is already registered

removeSensor

@Deprecated
void removeSensor(AttributeSensor sensor)
deprecated:
in 0.4. use new SensorAdapter model.
