Enum Constant Detail

REGISTERED

public static final ActivityState.State REGISTERED

The activity is registered for execution but the corresponding component is not initialised yet.

INITIALISING

public static final ActivityState.State INITIALISING

The component for the activity is currently initialising.

RUNNING

public static final ActivityState.State RUNNING

The component for the activity is currently executing.

TERMINATING

public static final ActivityState.State TERMINATING

The component for the activity has finished executing and is currently terminating.

TERMINATED

public static final ActivityState.State TERMINATED

The component for the activity has finished executing and has terminated. This is only relevant in case the component has just terminated or some information need to be kept in the runtime manager, for instance a URL for notifying the resume of the activity.

TERMINATED_PENDING

public static final ActivityState.State TERMINATED_PENDING

The component for the activity has finished executing and has terminated but activity termination could not be signalled to the execution manager. The termination signal is pending. This is only relevant in case of a persisting activity termination.

Method Detail

values

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

Returns:

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

valueOf

public static ActivityState.State valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null
