Constructor Detail

EntityListModel

public EntityListModel(Class<T> entityClass,
                       de.xima.cmn.criteria.QueryCriteriaManager qcm)

Method Detail

getAll

public List<T> getAll()

Specified by:

getAll in interface IEntityListModel<T extends ITransferableEntity>

Returns:

A list of all models, not including a #IEntityListModel.isNew(), unsaved model.

getAllPlusNew

public List<T> getAllPlusNew()

Specified by:

getAllPlusNew in interface IEntityListModel<T extends ITransferableEntity>

Returns:

A list of all models, including the #IEntityListModel.isNew(), unsaved model, if it exists.

updateData

public void updateData()

Specified by:

updateData in interface IUpdatable

selectDefault

protected void selectDefault()

Called when no item is selected. Should select the default item by calling #setSelected(ITransferableEntity). Defaults to selecting the first item; or a new item if no items exists. Override for custom behavior.

fetchAll

protected List<T> fetchAll()

Fetches all available entities. By default, this simple reads all entities matching the QueryCriteriaManager provided in the constructor. Override this for custom logic. If you choose to override this, you may provide null for the QueryCriteriaManager, if you do not call this super method and do not attempt to use it yourself.

Returns:

List All available entities. The order of the returned list is preserved.

addNew

public void addNew()

Description copied from interface: IEntityListModel

Sets the currently selected model to a new model. A new model is not yet persisted in the database and exists only in memory.

create

public void create()

update

public void update()

save

public void save(boolean addSuccessMessage,
                 boolean addErrorMessage)

save

public void save()

Description copied from interface: IEntityListModel

Saves the currently selected model to the database. If it IEntityListModel.isNew(), creates a new entry in the database, otherwise updates the existing entry.

Specified by:

public void setGlobalFilter(String globalFilter)

loadLazyData

public void loadLazyData()

Description copied from interface: IEntityListModel

Can be overriden to initialize lazily loaded fields on the entity. By default, does not load any lazy data.

Specified by:

loadLazyData in interface IEntityListModel<T extends ITransferableEntity>

setSelected

public void setSelected(T selected)

Description copied from interface: IEntityListModel

Sets the currently selected model to the given model. If the given model exists in the database but is not currently managed by an entity manager, rereads the model from the database. Thus the IEntityListModel.getSelected() model may not refer to the same instance as the given model.

Specified by:

Sets the list of filtered models. This should be subset of IEntityListModel.getAll().

Specified by:

setFiltered in interface IEntityListModel<T extends ITransferableEntity>

Parameters:

filtered - List of filtered models to set.

getMarked

public List<T> getMarked()

Specified by:

getMarked in interface IEntityListModel<T extends ITransferableEntity>

Returns:

List of entities that have been marked (i.e. for further processing)
