Method Detail

values

public static Statistic[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Statistic c : Statistic.values())
    System.out.println(c);

Returns:

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

valueOf

public static Statistic valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name

NullPointerException - if the argument is null

getSymbol

public String getSymbol()

fromSymbol

public static Statistic fromSymbol(String symbol)

Get a statistic from a symbol.

Parameters:

symbol - statistic to look up

Returns:

the value or null.

getDescription

public String getDescription()

toString

public String toString()

The string value is simply the symbol. This makes this operation very low cost.

Overrides:

toString in class Enum<Statistic>

Returns:

the symbol of this statistic.
