Constant Field Values

KEY_FLAVOR

public static final String KEY_FLAVOR

The name of the Shutter method to invoke.

See Also:

Constant Field Values

DEFNAME

public static final String DEFNAME

The default name.

See Also:

Constant Field Values

DEFSHUTTER

private static final String DEFSHUTTER

We link to the default shutter name.

See Also:

Constant Field Values

DEFFLAVOR

private static final String DEFFLAVOR

We link to the total shutter open time.

See Also:

Constant Field Values

shutter

private Shutter shutter

The reference to the Shutter driver.

timing

private Method timing

The method to invoke for retrieving the time.

Constructor Detail

ShutterTimes

public ShutterTimes(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 driver we depend on is now a different one. If only the method has changed, we try to get it from the driver.

Specified by:

rescanned in interface Reloadable

Overrides:

rescanned in class AbstractParameter

selectMethod

private boolean selectMethod()

We try to select the method stated by its name as the method to get the shutter time. If we already have a shutter driver assigned, we use this object to derive its class from, otherwise the shutter inter face is scanned. Only on reload, we might already have a shutter driver object.

probeMethod

private static Method probeMethod(String flavor,
                                  Class shutit)

Scan for the method with the given name in the stated class. The method must be callable with no arguments.

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

getFormatted

public String getFormatted()

Formatted return is in sec.

Specified by:

getFormatted in interface Parameter

Overrides:

getFormatted in class AbstractParameter
