Enum Constant Detail

FORWARD

public static final ScanDirection FORWARD

To retrieve possible target activities for forward transitions to continue the process but skip current activity.

BACKWARD

public static final ScanDirection BACKWARD

To retrieve backward transition targets to repeat a previous executed activity.

BOTH

public static final ScanDirection BOTH

To retrieve both transition targets: forward and backward.

Method Detail

values

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

Returns:

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

valueOf

public static ScanDirection 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
