org.apache.brooklyn.core.sensor.function.FunctionSensor<T>

All Implemented Interfaces:

EntityInitializer

public final class FunctionSensor<T>
extends AbstractAddSensorFeed<T>

Configurable EntityInitializer which adds a function sensor feed. This calls the function periodically, to compute the sensor's value.

Method Detail

apply

public void apply(EntityLocal entity)

Description copied from interface: EntityInitializer

Applies initialization logic to a just-built entity. Invoked immediately after the "init" call on the AbstractEntity constructed.

Specified by:

apply in interface EntityInitializer

Overrides:

apply in class AddSensor<T>

Parameters:

entity - guaranteed to be the actual implementation instance, thus guaranteed to be castable to EntityInternal which is often desired, or to the type at hand (it is not even a proxy)
