public class OneWireSwitch
extends AbstractSwitch
implements DriverDepending, Reloadable

A class providing access to a one-wire switch. This means the following:

• On construct, the name of the switch, the name of the one-wire server and the bit representing the switch are specified.
• On init, the switch binds to the registry, if #KEY_BIND is true.
• The parameter cluster must take care of registering the One-wire driver. For that, the switch implements the DriverDepending interface.
• During registering of the serial server, the switch is brought to a defined state given with the KEY_INITOFF key.

Constructor Detail

OneWireSwitch

public OneWireSwitch(Map prop)

Constructs a new light switch trigger. As a monitor for notification of cache-cahnged events, this trigger registers itself in the init section.
All additional properties have default values.

Method Detail

rescanned

public double rescanned(String key,
                        String old,
                        String newval)

As any parameter depending instance we fail if the parameter we depend on is now a different one.

Specified by:

rescanned in interface Reloadable

Overrides:

rescanned in class SimpleTrigger

init

public void init()

Initializes the one wire switch switch. If the timer class is null, it is defined here.

Specified by:

init in interface Initializable

Overrides:

init in class SimpleTrigger

registerDriver

public boolean registerDriver(Driver rs485)

Registers the driver. First, it is checked for instancy of OneWireDriver. If so, it's name is check to match the KEY_ONEWIRE name. If this, too, is fulfilled, an instance of this server is stored locally to allow sending of commands to the serial server.

Specified by:

registerDriver in interface DriverDepending

Returns:

True if registering at the driver was successful.

on

protected boolean on()

Turns the switch on. First, we read the state of the switch. If it is not on, we switch it to on. Note that this always reads the true state of the switch and does not relie on the internal trigger state as other programs may have manipulated the switch.

Specified by:

on in class AbstractSwitch

Returns:

True if successful.

off

protected boolean off()

Turn the light off. Sends the light-off command to the serial port.

Specified by:

off in class AbstractSwitch

Returns:

True if successful.

readSwitch

public String readSwitch()

Reads the switch.
