Interface WorkflowAgent.WorkflowProcessContext

All Superinterfaces:

BaseContext, SpecialistsBroker

Enclosing interface:

WorkflowAgent

public static interface WorkflowAgent.WorkflowProcessContext
extends BaseContext

Context representing a manual activity in the corresponding workflow process. Provides means to process the next workflow step.

The possible outgoing transitions of this activity targeting the next state are provided via getTransitions(). The user of this context has to decide which transition should be processed by calling doTransition(Transition). All data modifying methods like getFormData(), getTransitionParameters() must be called before calling doTransition(Transition) which completes the activity.

Attention:
Some methods will throw an UnsupportedOperationException if after doTransition(Transition) has been called or the activity has been processed automatically. In both cases isActivityProcessed() returns true.
The internal workflow implementation waits until doTransition(Transition) or gotoErrorState(String, Throwable) has been called. This can cause a timeout if the answer last too long.

5.0.207

Method Detail

isActivityProcessed

boolean isActivityProcessed()

Indicates whether the activity this context belongs to has been processed yet or not. After calling doTransition(Transition) this method will deliver true. If this context is provided after an activity with a script which has been processed automatically, this method will always deliver true.

Since:

5.0.207

doTransition(Transition)

getElement

@Nullable
IDProvider getElement()

Returns the element this workflow process is related to or null if this is a workflow without context.

Since:

doTransition

void doTransition(@Nullable
                Transition transition)

Process the next transition (one of getTransitions() and completes this workflow process activity. Use null to cancel the current activity process. This method can only be called once.

Throws:

UnsupportedOperationException - if this context is provided after an automatic activity or the activity has already been processed

Since:

5.0.207

getTransitions()

getTransitions

List<Transition> getTransitions()

Return the next possible transitions of the activity this context belongs to.

See Also:

doTransition(Transition)

getTransitionParameters

TransitionParameters getTransitionParameters()

Delivers the transition parameters object to be filled before calling doTransition(de.espirit.firstspirit.workflow.model.Transition). Calling doTransition(Transition) will set the transition in this parameters.

Throws:

UnsupportedOperationException - if this context is provided after an automatic activity or the activity has already been processed

Since:

getFormData

FormData getFormData()

Returns the custom form data object

Throws:

UnsupportedOperationException - if this context is provided after an automatic activity or the activity has already been processed

Since:

5.0.207

showActionDialog

@Nullable
Transition showActionDialog()

Shows an action gui dialog and returns the transition selected by the user. All input the user made will be persisted in the belonging transition parameters.

Throws:

UnsupportedOperationException - if this context is provided in headless mode or after an automatic activity or this process has already been processed (doTransition(Transition), gotoErrorState(String, Throwable) already called)

Since:

5.0.207

gotoErrorState

void gotoErrorState(@Nullable
                  String comment,
                  @Nullable
                  Throwable throwable)
                    throws IllegalStateException

Switch this task to the error state if it is defined.

Throws:

IllegalStateException - if the belonging workflow model has no error state

Since:

5.0.207

getErrorInfo

TaskErrorInfo getErrorInfo()

Returns the error info which has been set in gotoErrorState(String, Throwable), or null if not in error state.

Since:

getTask

Task getTask()

Returns the task this workflow process belongs to.
