Class SimpleWorkflowService<T extends StateAware>

java.lang.Object

org.egov.infra.workflow.service.SimpleWorkflowService<T>

All Implemented Interfaces:

WorkflowService<T>

public class SimpleWorkflowService<T extends StateAware>
extends Object
implements WorkflowService<T>

This is a generic bean so do not use this to do transition of your own StateAware objects
For your own StateAware object transition declare a separate bean definition like

 
       <bean id="myStateAwareWorkflowService" parent="workflowService">
               <constructor-arg index="0" ref="myStateAwarePersistenceService"/>
       </bean>

Method Detail

transition

public T transition(WorkflowAction workflowAction,
                    T stateAware,
                    String comments)

Description copied from interface: WorkflowService

Moves the stateAware from the current state to the next state. The actual logic of moving the stateAware depends on the state of the stateAware, and the Action

Specified by:

transition in interface WorkflowService<T extends StateAware>

Parameters:

workflowAction - the action

stateAware - the state aware stateAware

comments - the comment

Returns:

stateAware after state transition.

transition

public T transition(String actionName,
                    T stateAware,
                    String comment)

Description copied from interface: WorkflowService

Moves the stateAware from the current state to the next state. The actual logic of moving the stateAware depends on the state of the stateAware, the Action and the corresponding business rules encapsulated in a Script. The script name should be '.workflow.'. If this script was not found, the implementation will look for a script named '.workflow'. If this is not found either, then an EgovRuntimeException is thrown with the message key as 'workflow.script.notfound'

Specified by:

transition in interface WorkflowService<T extends StateAware>

Parameters:

actionName - the action name

stateAware - the state aware stateAware

comment - the comment

Returns:

stateAware after state transition.

getValidActions

public List<WorkflowAction> getValidActions(T stateAware)

Description copied from interface: WorkflowService

Returns a set of valid actions that can be executed on the stateAware. The actions are determined using the current state of the stateAware

Specified by:

getValidActions in interface WorkflowService<T extends StateAware>

Parameters:

stateAware - the state aware

Returns:

List of valid Actions

execute

public Object execute(T stateAware)

execute

public Object execute(T stateAware,
                      String comments)

getWfMatrix

public WorkFlowMatrix getWfMatrix(String type,
                                  String department,
                                  BigDecimal amountRule,
                                  String additionalRule,
                                  String currentState,
                                  String pendingActions)

Description copied from interface: WorkflowService

Returns WorkFlowMatrix for following combination of arguments

Specified by:

getWfMatrix in interface WorkflowService<T extends StateAware>

Parameters:

type - the Object type of object

department - Name of the department

amountRule - the amount

additionalRule - the additional rule defined for the objecttype

currentState - the current state of the object

pendingActions - the pendingActions for the objecttype

Returns:

WorkFlowMatrix Object

getWfMatrix

public WorkFlowMatrix getWfMatrix(String type,
                                  String department,
