Enum Constant	Description
end	Final state of the workflow.
manual	State that requires manual action.
normal	State that can be normally executed.
start	Initial states of the workflow.
wait	State for waiting something outside this instance to happen, including (but not limited to) child workflow instances to go to end state.

Method Summary

Modifier and Type	Method	Description
WorkflowInstance.WorkflowInstanceStatus	getStatus(org.joda.time.DateTime nextActivation)	Returns the status for this type.
boolean	isFinal()	Returns true is the state of this type is a final state, e.g.

Enum Constant Details

start

public static final WorkflowStateType start

Initial states of the workflow.

manual

public static final WorkflowStateType manual

State that requires manual action. Workflow execution is stopped.

normal

public static final WorkflowStateType normal

State that can be normally executed.

wait

public static final WorkflowStateType wait

State for waiting something outside this instance to happen, including (but not limited to) child workflow instances to go to end state. When a child workflow finishes and parent is in wait state, parent is automatically woken up.

end

public static final WorkflowStateType end

Final state of the workflow. Workflow execution is stopped.

Method Details

values

public static WorkflowStateType[] values()

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

Returns:

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

valueOf

public static WorkflowStateType valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null

isFinal

public boolean isFinal()

Returns true is the state of this type is a final state, e.g. a state after which the workflow processing is stopped. The workflow state can be moved to another state only by manual action.

Returns:

True for states of type manual and end, false for states of type start and normal.

getStatus

public WorkflowInstance.WorkflowInstanceStatus getStatus(org.joda.time.DateTime nextActivation)

Returns the status for this type. This is used when a workflow instance state is updated, the new status of the instance will be determined based on the new state type and next activation time.

Parameters:

nextActivation - The next activation for the instance.

Returns:

The status resolved for this state type and nextActivation.
