Method Details

values

public static FundamentalDiagram.Quantity[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static FundamentalDiagram.Quantity valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

label

public abstract String label()

Returns an axis label of the quantity.

Returns:

String; axis label of the quantity

format

public abstract String format(double value)

Formats a value for status display.

Parameters:

value - double; value

Returns:

String; formatted string including quantity

getValue

public abstract double getValue(FundamentalDiagram.FdSource src,
 int series,
 int item)

Get scaled value in presentation unit.

Parameters:

src - FdSource; the data source

series - int; series number

item - int; item number in series

Returns:

double; scaled value in presentation unit

computeOther

public abstract double computeOther(FundamentalDiagram.Quantity pairing,
 double thisValue,
 double pairedValue)

Compute the value of the 3rd quantity.

Parameters:

pairing - Quantity; quantity on other axis

thisValue - double; value of this quantity

pairedValue - double; value of the paired quantity on the other axis

Returns:

double; value of the 3rd quantity
