Method Detail

setWorkflowManagerAndNodeID

public void setWorkflowManagerAndNodeID(WorkflowManager wfm,
                                        NodeID id)

Description copied from interface: InteractiveView

Set access to workflowmanager and node so the view can trigger re-execution. Note part of the constructor, so derived classes don't have access to this information.

Specified by:

setWorkflowManagerAndNodeID in interface InteractiveView<T extends NodeModel & WizardNode<REP,VAL>,REP extends WebViewContent,VAL extends WebViewContent>

Parameters:

wfm - the parent WorkflowManager

id - of the node

canReExecute

public boolean canReExecute()

Specified by:

canReExecute in interface InteractiveView<T extends NodeModel & WizardNode<REP,VAL>,REP extends WebViewContent,VAL extends WebViewContent>

Returns:

true if node can be re-executed.

triggerReExecution

public void triggerReExecution(VAL value,
                               boolean useAsNewDefault,
                               ReexecutionCallback callback)

Description copied from interface: InteractiveView

Re-Execute underlying node. Also trigger:
- reset of node and successors (ask user first!)
- configure node and successors
- execute node but not successors (can be canceled by user of fail during execution!)

Specified by:

triggerReExecution in interface InteractiveView<T extends NodeModel & WizardNode<REP,VAL>,REP extends WebViewContent,VAL extends WebViewContent>

callback - Callback for confirm messages and progress information.

Since:

2.10

getViewSource

protected File getViewSource()

Returns:

The current html file object.

callCloseView

protected void callCloseView()

Called from AbstractNodeView.closeView() to close the view and release all allocated resources. The view will not be opened again.

Specified by:

callCloseView in class AbstractNodeView<T extends NodeModel & WizardNode<REP,VAL>>

getViewCreator

protected WizardViewCreator<REP,VAL> getViewCreator()

Returns:

The node views creator instance.

closeView

protected abstract void closeView()

Called on view close.

getAllWizardNodeViews

public static List<AbstractWizardNodeView.WizardNodeViewExtension> getAllWizardNodeViews()

Queries extension point for additional AbstractWizardNodeView implementations.

Returns:

A list with all registered view implementations.
