public abstract class AbstractMultiItemAction<D extends info.magnolia.ui.api.action.ActionDefinition>
extends info.magnolia.ui.api.action.AbstractAction<D>

Abstract multi-item Action that defines the default behavior.

Constructor Summary

protected	AbstractMultiItemAction(D definition, info.magnolia.ui.vaadin.integration.jcr.JcrItemAdapter item, info.magnolia.ui.api.context.UiContext uiContext)
protected	AbstractMultiItemAction(D definition, List<info.magnolia.ui.vaadin.integration.jcr.JcrItemAdapter> items, info.magnolia.ui.api.context.UiContext uiContext)

Method Summary

void	execute()
protected abstract void	executeOnItem(info.magnolia.ui.vaadin.integration.jcr.JcrItemAdapter item) Executes the action on ONE item.
protected info.magnolia.ui.vaadin.integration.jcr.JcrItemAdapter	getCurrentItem() Returns the item that is currently being processed - i.e.
protected String	getErrorNotification()
protected Map<info.magnolia.ui.vaadin.integration.jcr.JcrItemAdapter,Exception>	getFailedItems()
protected abstract String	getFailureMessage() Returns the message to display, if the execution fails on at least ONE item.
protected Comparator<info.magnolia.ui.vaadin.integration.jcr.JcrItemAdapter>	getItemComparator() Create a Comparator used to sort JcrItemAdapter.
protected List<info.magnolia.ui.vaadin.integration.jcr.JcrItemAdapter>	getItems()
protected List<info.magnolia.ui.vaadin.integration.jcr.JcrItemAdapter>	getSortedItems(Comparator<info.magnolia.ui.vaadin.integration.jcr.JcrItemAdapter> comparator)
protected abstract String	getSuccessMessage() Returns the message to display, if the execution succeeds on ALL items.
protected info.magnolia.ui.api.context.UiContext	getUiContext()
protected void	setCurrentItem(info.magnolia.ui.vaadin.integration.jcr.JcrItemAdapter item) This method should be used only in tests (when the test does not call the execute() method but e.g. only the AbstractCommandAction.onPreExecute() so the current item hasn't been set.

Executes the action on ONE item.

Throws:

Exception

getSuccessMessage

protected abstract String getSuccessMessage()

Returns the message to display, if the execution succeeds on ALL items. May return null, if the implementing action handles the user notification on its own.

getFailureMessage

protected abstract String getFailureMessage()

Returns the message to display, if the execution fails on at least ONE item. May return null, if the implementing action handles the user notification on its own.

public void execute()
             throws info.magnolia.ui.api.action.ActionExecutionException
