ClientPersistentFieldStorage,PersistentFieldStrategy
@Scope("perthread") public class ClientPersistentFieldStorageImpl extends java.lang.Object implements ClientPersistentFieldStorage

Description copied from interface:ClientPersistentFieldStorageUpdates a link, adding a query parameter to it (if necessary) to store- Specified by:

public java.util.Collection<PersistentFieldChange> gatherFieldChanges(java.lang.String pageName)
Description copied from interface:PersistentFieldStrategyFinds all persistent changes previously stored for the named page (for the current active session or client).- Specified by:

-
discardChanges
public void discardChanges(java.lang.String pageName)
Description copied from interface:PersistentFieldStrategyDiscards any saved changes for the name page. There is no expectation that data already gathered from the strategy and presumably dumped into component instance fields will be affected, but future field access (within this request or a later one) will show no data for the indicated page.- Specified by:
discardChangesin interfacePersistentFieldStrategy- Parameters:
pageName- logical name of page whose field persistent data should be discarded
-
postChange
public void postChange(java.lang.String pageName, java.lang.String componentId, java.lang.String fieldName, java.lang.Object newValue)
Description copied from interface:PersistentFieldStrategyPosts a change of a persistent property.- Specified by:
postChangein interfacePersistentFieldStrategy- Parameters:
pageName- the name of the page containing the componentcomponentId- the nested id path of the component (or null for the page's root component)fieldName- the name of the field whose persistent value has changednewValue- the new value for the field, possibly null
