public final class DomeMaster
extends ShelterMaster
implements DomeControlling, Reloadable

The master program running at the environment control. It comprises dome control and a weather station. The environment master is not directly controling the weather station or the dome but merely acts as a high-level control device and speaks to the waether station via the WeatherSurveying interface and to the roof via the DomeOperating interface. Since version 1.1 also the command handling abilities (RmiCommandListener, RmiAcknowledgeCaster and RmiDoneCaster) are embedded within the environment master rather than within the roof receiver. To allow remote control of the environment this class supports building control via the BuildingControlling interface. This interface allows the remote registering and deregistering of command casters and can thus be used to change the roof mode between automatic, when the command caster is the SCS, and manual, when the registered command caster is a launch box.

The principal idea is that the roof may only have a single driver object registered to itself, while the weather station can get an entire list of driveres, all registered sequentially by calls to the weather station's WeatherSurveying.registerSensorDriver(io.Driver) method. For implementations where the weather station and the roof control uses the same hardware for reading sensors and operating relays, a common driver can be used if the #KEY_COMMONDRIVER is present. In this case, this single driver is constructed and initialized once and then registered at both, the roof operator and the weather surveyer. If this key is not set, the ShelterMaster.KEY_WEATHERDRIVER and the #KEY_ROOFDRIVER are used to specify two different drivers for the roof operator (single driver only) and the weather surveyer (can be a list of drivers), respectively.
If the host is booted and the environment master is started for the first time, the GenericMaster.KEY_AUTOMATIC key determines whether automatic roof control is immediately enabled: If this property is true the environment master tries to register at the #KEY_ENVIRONMENTCASTER as a command listener immediately after startup, otherwise no command caster is registered at. If the environment master starts up in manual mode the #KEY_STARTUPROOF is read and the actual position of the roof is compared to the desired position. Possible values of #KEY_STARTUPROOF are: close to close the roof if found open at boot, open to open the roof if found close, indifferent if the roof should be left in whatever state encountered. See also #ROOF_OPEN, #ROOF_CLOSE, and #ROOF_INDIFFERENT.
If the weather station is hosted on the same machine as the roof control it may be advisable to directly link bad-weather events to a close-roof command, in case of lost connection to the SCS. If this behaviour is desired, the ShelterMaster.KEY_DIRECTCLOSE key should point to true. For direct opening, the ShelterMaster.KEY_DIRECTOPEN may be used. Note that direct linking is only enabled in automatic mode.
Note that the ReceiverTorso.KEY_BIND-key only determines if the environment master should nail its building control ability to the rmi-registry. The binding of the weather station and of the roof receiver is determined within their own property files.
