Method Details

builder

public static <T extends de.xima.cmn.dao.interfaces.IEntity<Long>>
DaoLazyDataModel.Builder<T> builder(EEntityKeySelectionType keyType,
 Class<T> entityClass)

Creates a new builder for a lazy entity list model.

Type Parameters:

T - Type of the entity to store in the lazy list model.

Parameters:

keyType - Scope of the entity that determines how the currently selected entity is stored. Used to restore the last selected entity when the UI is reloaded.

entityClass - Type of the entity.

Returns:

A new builder for configuring a lazy entity list model.

load

public List<T> load(int first,
 int pageSize,
 Map<String,org.primefaces.model.SortMeta> sortBy,
 Map<String,org.primefaces.model.FilterMeta> filterBy)

Specified by:

load in class org.primefaces.model.LazyDataModel<T extends de.xima.cmn.dao.interfaces.IEntity<Long>>

count

public int count(Map<String,org.primefaces.model.FilterMeta> filterBy)

Specified by:

count in class org.primefaces.model.LazyDataModel<T extends de.xima.cmn.dao.interfaces.IEntity<Long>>

getRowKey

public String getRowKey(T entity)

Specified by:

getRowKey in interface org.primefaces.model.SelectableDataModel<T extends de.xima.cmn.dao.interfaces.IEntity<Long>>

Overrides:

getRowKey in class org.primefaces.model.LazyDataModel<T extends de.xima.cmn.dao.interfaces.IEntity<Long>>

getSelected

public T getSelected()

Returns:

The currently selected entity.

setSelected

public void setSelected(T selected)

Parameters:

selected - The entity to select.

getMarked

public List<T> getMarked()

setMarked

public void setMarked(List<T> marked)

setSortingCriterions

public void setSortingCriterions(List<IEntitySortingCriterion> sortingCriterions)

setAdditionalFilters

public void setAdditionalFilters(List<IFilterCriterionSupplier> additionalFilters)

setFirst

public void setFirst(int first)

Parameters:

first - The index of the first item of the page to display.

getFirst

public int getFirst()

Returns:

The index of the first item of the page to display.

selectFirstOfPage

public void selectFirstOfPage()

Selects the first item on the current page, if such an item exists.

moveToPageOfSelected

public void moveToPageOfSelected()

Switches to the page that contains the currently selected item.

restoreSavedSelection

public void restoreSavedSelection()

Reads the last selected entity, and, if such an entity exists, selects that entity. This should usually be called only once for a given UI page, after the model was created.

getDao

protected final IGenericDao<T> getDao()
