Constructor Summary

PilarValue(Map<String,String> prop)
Constructs a new pilar value from the properties.

Method Summary

Number	getValue() Gets the pilar response either from the cache or from the underlying telescope and trie to parse it into a Number.
void	init() On init, try to load our parser class.
private boolean	initParserClass() We try to use the parser class for converting string answers from the pilar driver to number instances.
double	rescanned(String key, String old, String newval) If the parser class changed, we try to rebuild it.
Number	setValue(Number to) Setting a number is not allowed.

Field Detail

KEY_VALUECLASS

public static final String KEY_VALUECLASS

The name of number class used to parse the parameter from.

See Also:

Constant Field Values

DEFVALUECLASS

private static final String DEFVALUECLASS

Default value class is Double.

See Also:

Constant Field Values

number

private Class<? extends Number> number

We use this class for parsing strings to numbers.

Constructor Detail

PilarValue

public PilarValue(Map<String,String> prop)

Constructs a new pilar value from the properties.

Method Detail

init

public void init()

On init, try to load our parser class.

Specified by:

init in interface Initializable

Overrides:

init in class AbstractParameter

initParserClass

private boolean initParserClass()

We try to use the parser class for converting string answers from the pilar driver to number instances. Defaults to Double class.

Returns:

True, if the class was found and is usable.

rescanned

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

If the parser class changed, we try to rebuild it.

Specified by:

rescanned in interface Reloadable

Overrides:

rescanned in class PilarParameter

getValue

public Number getValue()

Gets the pilar response either from the cache or from the underlying telescope and trie to parse it into a Number. The number class can be specified in the properties.

Specified by:

getValue in interface Value

setValue

public Number setValue(Number to)

Setting a number is not allowed. This is done only within certain commands of a PilarDriver

Specified by:

setValue in interface Value
