Field Detail

KEY_VAL1

public static final String KEY_VAL1

The name of the parameter that gives the value of the first point.

See Also:

Constant Field Values

KEY_VAL2

public static final String KEY_VAL2

The name of the parameter that gives the value of the second point.

See Also:

Constant Field Values

val1

private Value val1

The value of the first point.

val2

private Value val2

The value of the seconf point.

Constructor Detail

ValueFraction

public ValueFraction(Map<String,String> prop)

Constructs a new distance parameter. The default name is not specific. None of the two points assumes any default val;ue.

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

registerParameter

public void registerParameter(Parameter what)

Registers the parameters giving the ra, dec of two points. No checks for types are made, only the parameter name counts.

Specified by:

registerParameter in interface ParameterDepending

getValue

public Number getValue()

Returns the addition of the both values.

Specified by:

getValue in interface Value

setValue

public Number setValue(Number val)
                throws UnsupportedOperationException

Sets the sum. This is a read-only variable, therefore this method throws an UnsupportedOperationException.

Specified by:

setValue in interface Value

Throws:

UnsupportedOperationException
