public class FilterWheelPosition
extends AbstractValue
implements DriverDepending

Records the position of a Positioning driver, which is useful if this driver is a filter wheel. This parameter is driver depending and keeps a reference to Positioning, if this driver has the correct name in KEY_FILTERWHEEL. Setting the value is not allowed, on get, the filter wheel position is returned as an Integer.

Constructor Detail

FilterWheelPosition

public FilterWheelPosition(Map<String,String> prop)

Constructs a new filter wheel parameter, defaulting its name and the name of the Positioning driver.

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.

Overrides:

rescanned in class AbstractParameter

registerDriver

public boolean registerDriver(Driver fw)

Registers the driver. If it is Positioning and its name equals KEY_FILTERWHEEL, we keep a reference to it.

Specified by:

registerDriver in interface DriverDepending

Returns:

True if registering at the driver was successful.

getValue

public Number getValue()

Tries to get the position of the filterwheel as an integer.

Specified by:

getValue in interface Value

setValue

public Number setValue(Number to)

Not allowed

Specified by:

setValue in interface Value
