Method Detail

values

public static Severity[] 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 (Severity c : Severity.values())
    System.out.println(c);

Returns:

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

valueOf

public static Severity 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

fromNumericalCode

public static Severity fromNumericalCode(int numericalCode)
                                  throws IllegalArgumentException

Parameters:

numericalCode - Syslog severity numerical code

Returns:

Syslog severity, not null

Throws:

IllegalArgumentException - the given numericalCode is not a valid Syslog severity numerical code

fromLabel

public static Severity fromLabel(String label)
                          throws IllegalArgumentException

Parameters:

label - Syslog severity textual code. null or empty returns null

Returns:

Syslog severity, null if given value is null

Throws:

IllegalArgumentException - the given value is not a valid Syslog severity textual code

numericalCode

public int numericalCode()

Syslog severity numerical code

label

public String label()

Syslog severity textual code. Not null.

comparator

public static Comparator<Severity> comparator()

Compare on numericalCode()
