public interface Workflow
extends BusinessSmartComponent

A Business Smart Component (BSC) Workflow provides access to a remote instance of a BSC Workflow Implementation. A workflow defines an abstract interface to an object that implements a set of states and legal transitions between those states. This is a powerful metaphor that represents a variety of decision support structures. An implementation of a Workflow is the StateMachine class in The Theory Center's Axiom package. The Theory Center's SmartGenerator generates a workflow based on that StateMachine, directly from a State Diagram

String[]	getOutgoingTransitions(String state) Deprecated Get all transition names with the start state passed in.
String[]	getStateNames() Deprecated Get all State names in an array of Strings.
String[]	getTransitionNames() Deprecated Get all transition names in an array of Strings.
String	lookAheadTransition(String transition) Deprecated Given the name of the transition, look ahead the transition and return the predicted new state.

Method Detail

doTransition

String doTransition(String transitionName)
                    throws IllegalWorkflowTransitionException

Deprecated

Atempt to execute the specified transition and return the resulting state. If the specified transition is not allowed by the Workflow specification an InvalidWorkflowTransitionException will be thrown.

Parameters

transition - the name of the transition to be performed

Returns

new state.

Throws

IllegalWorkflowTransitionException - if the transition is invalid

getContext

WorkflowContext getContext()

Deprecated

This method returns a Workflow context that can be used to later restore a Workflow. WorkflowContext is serializable and thus the WorkflowContext is the mechanism by which a Workflow is persisted. This method should be used only by the classes that implement the Workflow interface.

Returns

WorkflowContext

getCurrentStateName

String getCurrentStateName()

Deprecated

Get the name of the current state

Returns

current state name

getInitialStateName

String getInitialStateName()

Deprecated

Get the name of the initial state

Returns

initial state name

getStateNames

String[] getStateNames()

Deprecated

Get all State names in an array of Strings.

Returns

String[] an array of Strings

getTransitionNames

String[] getTransitionNames()

Deprecated

Get all transition names in an array of Strings.

Returns

String[] an array of Strings

getOutgoingTransitions

String[] getOutgoingTransitions(String state)
                                throws IllegalWorkflowTransitionException

Deprecated

Get all transition names with the start state passed in.

Returns

String[] an array of Strings

Throws

IllegalWorkflowTransitionException

lookAheadTransition

String lookAheadTransition(String transition)
                           throws IllegalWorkflowTransitionException

Deprecated

Given the name of the transition, look ahead the transition and return the predicted new state. If transition is invalid for the current state of the state machine, throw IllegalWorkflowTransitionException.

Parameters

transition - the name of the transition to be performed

Returns

predicted new state.

Throws

IllegalWorkflowTransitionException - if the transition is invalid

reset

void reset()

Deprecated

Reset the current workflow state to the initial state

setContext

void setContext(WorkflowContext workflowContext)

Deprecated

Set the new context for the underlying workflow engine. This method should be used only by the classes that implement the Workflow interface.

Parameters

WorkflowContext - the new context for the underlying workflow engine.
