DynamoDBStore

public DynamoDBStore()

Method Detail

create

public V create()

Description copied from interface: Store

Create a new object of the given type. This is not in the store until it is registered. Attempts to update the object should throw an exception. Note that this allows for a separation of creation semantics. Some objects require specific initialization before saving

Specified by:

create in interface Store<V extends Identifiable>

Returns:

update

public void update(V value)

Description copied from interface: Store

Update an existing object. An UnregisteredObjectException is thrown if the object has not been saved first.

Specified by:

update in interface Store<V extends Identifiable>

register

public void register(V value)

Description copied from interface: Store

Almost Identical to put(K,V) but since the object should have an identifier, passing along the key is redundant. This persists the object in the store. Note that this returns void since the contract assumes that this is not registered. If the object is registered an exception should be thrown. Generally use save(V).

Specified by:

register in interface Store<V extends Identifiable>

save

public void save(V value)

Description copied from interface: Store

Saves an object. This bridges the gap between SQL stores update and insert commands. Implementations should check if the object already exists in the store and issue an appropriate call.

Specified by:

save in interface Store<V extends Identifiable>

getAll

public List<V> getAll()

Description copied from interface: Store

Method to get every element in the store. This is useful for command line interfaces. Note that this might be very expensive.

Specified by:

getAll in interface Store<V extends Identifiable>

Returns:

getXMLConverter

public XMLConverter<V> getXMLConverter()

Specified by:

getXMLConverter in interface Store<V extends Identifiable>

search

public List<V> search(String key,
                      String condition,
                      boolean isRegEx)

Description copied from interface: Store

Allows for searching via a reg ex. Note that this may be very expensive for certain stores!

Specified by:

search in interface Store<V extends Identifiable>

Returns:

search

public List<V> search(String key,
                      String condition,
                      boolean isRegEx,
                      List<String> attr)

Description copied from interface: Store

Return a subset of all the attributes. For non-SQL stores performance may be slow.

Specified by:

search in interface Store<V extends Identifiable>

Returns:

search

public List<V> search(String key,
                      String condition,
                      boolean isRegEx,
                      List<String> attr,
                      String dateField,
                      Date before,
                      Date after)

Specified by:

search in interface Store<V extends Identifiable>

size

public int size(boolean includeVersions)

Specified by:

size in interface Store<V extends Identifiable>

remove

public boolean remove(List<Identifiable> objects)

Description copied from interface: Store

Removes a list of identifiable object from the store by ID.

Specified by:

remove in interface Store<V extends Identifiable>

Returns:

getMostRecent

public List<V> getMostRecent(int n,
                             List<String> attributes)

Specified by:

getMostRecent in interface Store<V extends Identifiable>

size

Specified by:

isEmpty in interface Map<Identifier,V extends Identifiable>
