Method Detail

values

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

Returns:

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

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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

find

public static final Position find(java.lang.String positionInfo)

Find the Position enum value used in the given positioning string.

Parameters:

positionInfo - the positioning string (can be null, which would result in null)

Returns:

the Position which is mentioned in the positioning string, or null if none can be found
