public class ConfigurableDouble

extends Configurable

ConfigurableDouble extends the Configurable class to contain a double variable, and provides new methods for the world to interface with that variable. It overrides the set(String) methods and the toString() methods of Configurable. ConfigurableDouble is also set up to be an observable. Source code is available.

ConfigurableDouble(double)

This constructor allows a ConfigurableDouble to be constructed which exists outside the Configurable heirarchy and does not use its configurable functionality.

ConfigurableDouble(double, String, String)

This constructor allows a ConfigurableDouble to be constructed outside of the tree structure, but with short and long names.

ConfigurableDouble(ConfigurableCollection, String, String, int, double)

This constructor is used to create a full-fledged ConfigurableDouble with all of the functionality of a Configurable.

ConfigurableDouble(ConfigurableCollection, String, String, int, String)

This constructor is used to create a full-fledged ConfigurableDouble with all of the functionality of a Configurable.

doubleValue()

The doubleValue() method of ConfigurableDouble returns the value of the ConfigurableDouble as a double.

set(String)

The set(String) method of ConfigurableDouble takes a string as its argument, (e.g.

set(double)

We often will want to set the value of our ConfigurableDouble using a double, rather than a string, so we provide a set(double) method.

toString()

The toString() method of ConfigurableDouble returns a string representing the value of the ConfigurableDouble.

  public ConfigurableDouble(double value)

This constructor allows a ConfigurableDouble to be constructed which exists outside the Configurable heirarchy and does not use its configurable functionality.

Parameters:

value - The initial value of the ConfigurableDouble

  public ConfigurableDouble(double value,
                            String shortName,
                            String longName)

This constructor allows a ConfigurableDouble to be constructed outside of the tree structure, but with short and long names.

Parameters:

value - The initial value of the ConfigurableDouble

shortName - The short name of the ConfigurableDouble

longName - The long name of the ConfigurableDouble

  public ConfigurableDouble(ConfigurableCollection parent,
                            String shortName,
                            String longName,
                            int att,
                            double defaultVal)

This constructor is used to create a full-fledged ConfigurableDouble with all of the functionality of a Configurable. It takes a double default value, rather than a String.

Parameters:

parent - A reference to the parent ConfigurableCollection

shortName - The short name of the ConfigurableDouble

longName - The long name of the ConfigurableDouble

att - The attributes of the ConfigurableDouble

defaultVal - The default value of the ConfigurableDouble

  public ConfigurableDouble(ConfigurableCollection parent,
                            String shortName,
                            String longName,
                            int att,
                            String defaultVal)

This constructor is used to create a full-fledged ConfigurableDouble with all of the functionality of a Configurable. It takes a String to set the default value.

Parameters:

parent - A reference to the parent ConfigurableCollection

shortName - The short name of the ConfigurableDouble

longName - The long name of the ConfigurableDouble

att - The attributes of the ConfigurableDouble

defaultVal - The default value of the ConfigurableDouble

  public boolean set(String value)

The set(String) method of ConfigurableDouble takes a string as its argument, (e.g. "0.5 E 15") and uses it to set the value of the ConfigurableDouble. Observers will be notified of the change.

Parameters:

value - The value to set the ConfigurableDouble to.

Returns:

true is returned if the set is successful, false if unsuccessful.

Overrides:

set in class Configurable

  public void set(double value)

We often will want to set the value of our ConfigurableDouble using a double, rather than a string, so we provide a set(double) method. Observers are notified of the change in value.

Parameters:

value - The value to set the ConfigurableDouble to

  public String toString()

The toString() method of ConfigurableDouble returns a string representing the value of the ConfigurableDouble.

Returns:

A string containing the vlaue of the ConfigurableDouble

Overrides:

toString in class Configurable

  public double doubleValue()

The doubleValue() method of ConfigurableDouble returns the value of the ConfigurableDouble as a double.

Returns:

A double containing the value of the ConfigurableDouble.
