Method Details

values

public static Signal[] values()

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

Returns:

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

valueOf

public static Signal 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

getNumeric

public int getNumeric()

Returns:

The signal's numeric value

get

public static Signal get(String name)

Retrieves a signal value given its name

Parameters:

name - The signal's name (case insensitive) - ignored if null/empty

Returns:

The matching Signal or null if no match found

get

public static Signal get(int num)

Retrieves a signal value given its numeric value

Parameters:

num - The signal's numeric value

Returns:

The matching Signal or null if no match found
