Method Detail
-
requestUpdateFromLayout
public void requestUpdateFromLayout()
Request an update on status by sending an Instruction to the Pi.- Specified by:
requestUpdateFromLayout
in interfaceDigitalIO
-
handleGpioPinDigitalStateChangeEvent
public void handleGpioPinDigitalStateChangeEvent(com.pi4j.io.gpio.event.GpioPinDigitalStateChangeEvent event)
- Specified by:
handleGpioPinDigitalStateChangeEvent
in interfacecom.pi4j.io.gpio.event.GpioPinListenerDigital
-
setPullResistance
public void setPullResistance(Sensor.PullResistance r)
Set the pull resistance.In this default implementation, the input value is ignored.
- Specified by:
setPullResistance
in interfaceSensor
- Overrides:
setPullResistance
in classAbstractSensor
- Parameters:
r
- PullResistance value to use.
-
getPullResistance
public Sensor.PullResistance getPullResistance()
Get the pull resistance- Specified by:
getPullResistance
in interfaceSensor
- Overrides:
getPullResistance
in classAbstractSensor
- Returns:
- the currently set PullResistance value. In this default implementation, PullResistance.PULL_OFF is always returned.
-
dispose
public void dispose()
Description copied from class:AbstractNamedBean
Deactivate this object, so that it releases as many resources as possible and no longer effects others.For example, if this object has listeners, after a call to this method it should no longer notify those listeners. Any native or system-wide resources it maintains should be released, including threads, files, etc.
It is an error to invoke any other methods on this object once dispose() has been called. Note, however, that there is no guarantee about behavior in that case.
Afterwards, references to this object may still exist elsewhere, preventing its garbage collection. But it's formally dead, and shouldn't be keeping any other objects alive. Therefore, this method should null out any references to other objects that this NamedBean contained.
