public class GenericStoreUtils
extends Object

This is where static generic methods for stores like searches live. These are horribly inefficient but sometimes there is no other way. The intent is that if you need to use these, they are centralized to prevent boiler plating.

Method Detail

search

public static <V extends Identifiable> List<V> search(Store<V> store,
                                                      String key,
                                                      String condition,
                                                      boolean isRegEx,
                                                      List<String> attr)

search

public static <V extends Identifiable> List<V> search(Store<V> store,
                                                      String key,
                                                      String condition,
                                                      boolean isRegEx,
                                                      List<String> attr,
                                                      String dateField,
                                                      Date before,
                                                      Date after)

getMostRecent

public static <V extends Identifiable> List<V> getMostRecent(Store<V> store,
                                                             int n,
                                                             List<String> attributes)

toXML

public static XMLMap toXML(Store store,
                           Identifiable identifiable)

Convert an identifiable object to an XMLMap. This is useful for serializing objects in the store, backing them up, etc.

Parameters:

store -

identifiable -

Returns:

fromXML

public static Identifiable fromXML(Store store,
                                   XMLMap map)

This will convert a map into an object. You must issue a save separately or if you prefer, fromXMLAndSave(Store, XMLMap).

Parameters:

store -

map -

Returns:

fromXMLAndSave

public static void fromXMLAndSave(Store store,
                                  XMLMap map)

update

public static <V extends Identifiable> void update(Store<V> store,
                                                   List<Identifier> ids,
                                                   Map<String,Object> values)

Generic implementation of Store.update(List, Map) and will loop through the elements doing the update one at a time. If the store has the capability at all for batch processing, implement it. This is for things like MemoryStores and FileStores that have no such ability. Note that part of the contract is that the element must exist and an exception is thrown of there is no such element.

Parameters:

store -

ids -

values -

search

public static <V extends Identifiable> List<V> search(Store<V> store,
                                                      String key,
                                                      boolean isNull)
