Method Detail

store

public void store(String pageName,
                  String idPath,
                  String propertyName,
                  Object newValue)

Description copied from interface: PropertyPersistenceStrategy

Stores the new value.

Specified by:

store in interface PropertyPersistenceStrategy

Parameters:

pageName - the name of the page containing the property

idPath - the path to the component with the property (may be null)

propertyName - the name of the property to be persisted

newValue - the new value (which may be null)

getStoredChanges

public Collection getStoredChanges(String pageName)

Description copied from interface: PropertyPersistenceStrategy

Returns a collection of PropertyChanges. These represent prior changes previously stored. The order is not significant. Must not return null. Does not have to reflect changes made during the current request (this method is typically invoked as part of rolling back a page to a prior state, before any further changes are possible).

Specified by:

getStoredChanges in interface PropertyPersistenceStrategy

discardStoredChanges

public void discardStoredChanges(String pageName)

Description copied from interface: PropertyPersistenceStrategy

Invoked to discard any stored changes for the specified page.

Specified by:

discardStoredChanges in interface PropertyPersistenceStrategy

addParametersForPersistentProperties

public void addParametersForPersistentProperties(ServiceEncoding encoding,
                                                 boolean post)

Does nothing; session persistence does not make use of query parameters.

Specified by:

addParametersForPersistentProperties in interface PropertyPersistenceStrategy

Parameters:

encoding - Service encoding, which indentifies the URL and the query parameters from which the ILink will be created.

post - if true, then the link will be used for a post (not a get, i.e., for a HTML form); this may affect what information is encoded into the link
