Enum Constant Detail

STATE_UNAFFECTED

public static final StateImpact STATE_UNAFFECTED

The application state is safe and not affected by the rollback. This can be guaranteed only if no rolled-back events have been passed to the event applier yet.

STATE_CORRUPTION_POSSIBLE

public static final StateImpact STATE_CORRUPTION_POSSIBLE

The application state is possibly corrupted since some of the events rolled back have already been passed to the event applier. The application state is safe only if either

• all events passed to the event applier did not modify application state, or
• undo events were routed prior to the rollback to revert the application state to the original values

Method Detail

values

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

Returns:

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

valueOf

public static StateImpact 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
