Class DoubleParameter

java.lang.Object

jcgp.backend.parameters.Parameter<java.lang.Number>

jcgp.backend.parameters.DoubleParameter

Direct Known Subclasses:

DoubleMonitor

public class DoubleParameter
extends Parameter<java.lang.Number>

Parameter subclass for the double type. Most of the functionality is already implemented in Parameter, leaving only construction and type definition to the subclasses.

This class contains three constructors, two of which are public. One assumes the parameter is not critical and only takes a name and initial value, while the other allows the critical flag to be set as well. The third constructor is protected and allows the monitor flag to be set as well, allowing subclasses of this class to be used as monitors. See DoubleMonitor for an example of this usage.

The validate method is overridden here and left blank since not all parameters actually require validation, but where validation is required this method can be anonymously overridden on an instance-to-instance basis.

Method Detail

get

public java.lang.Double get()

Overrides:

get in class Parameter<java.lang.Number>

Returns:

the parameter's current value.

validate

public void validate(java.lang.Number newValue)

Description copied from class: Parameter

This is a callback method which gets called whenever changes to parameters (not only its own instance) are made. This method is intended to set the status field according to the new value, so that the user can be informed if any parameters are currently set to invalid values.

Specified by:

validate in class Parameter<java.lang.Number>

Parameters:

newValue - the new value.
