 Class<E> entityClass,
 Function<? extends LookupWindowBuilder<E,V>,DialogWindow<V>> handler)

Method Details

withViewId

public LookupWindowBuilder<E,V> withViewId(@Nullable
 String viewId)

Sets identifier of the opened view as specified in the ViewController annotation.

Parameters:

viewId - identifier of the opened view as specified in the ViewController annotation

Returns:

this instance for chaining

withViewClass

public <T extends View<?> & LookupView<E>>
LookupWindowClassBuilder<E,T> withViewClass(Class<T> viewClass)

Sets opened view class.

Type Parameters:

T - view type

Parameters:

viewClass - opened view class

Returns:

LookupWindowClassBuilder instance for chaining

withSelectHandler

public LookupWindowBuilder<E,V> withSelectHandler(Consumer<Collection<E>> selectHandler)

Sets selection handler for the lookup view.

Parameters:

selectHandler - handler to set

Returns:

this instance for chaining

withSelectValidator

public LookupWindowBuilder<E,V> withSelectValidator(Predicate<LookupView.ValidationContext<E>> selectValidator)

Sets selection validator for the lookup view.

Parameters:

selectValidator - validator to set

Returns:

this instance for chaining

withTransformation

public LookupWindowBuilder<E,V> withTransformation(@Nullable
 Function<Collection<E>,Collection<E>> transformation)

• withField(HasValue)
• withMultiValueField(HasValue)
• withListDataComponent(ListDataComponent)

withContainer

public LookupWindowBuilder<E,V> withContainer(@Nullable
 CollectionContainer<E> container)

Sets CollectionContainer to updated after the lookup view is closed.

If the container is Nested, the framework automatically initializes the reference to the parent entity and sets up data contexts for added One-To-Many and Many-To-Many relations.

Parameters:

container - the container to update after the lookup view is closed

Returns:

this instance for chaining

withListDataComponent

public LookupWindowBuilder<E,V> withListDataComponent(@Nullable
 ListDataComponent<E> listDataComponent)

Sets list data component that is used to get the container if it is not set explicitly by withContainer(CollectionContainer) method.

Usually, the list component is a DataGrid displaying the list of entities.

Parameters:

listDataComponent - the component to set

Returns:

this instance for chaining

withField

public <T extends com.vaadin.flow.component.HasValue<?,
E>>
LookupWindowBuilder<E,V> withField(@Nullable
 T field)

Sets the field in which the framework sets the selected entity after successful lookup.

Parameters:

field - the field to set

Returns:

this instance for chaining

withMultiValueField

public <T extends com.vaadin.flow.component.HasValue<?,
Collection<E>>>
LookupWindowBuilder<E,V> withMultiValueField(@Nullable
 T field)

Sets the field in which the framework sets the selected entities after successful lookup.

Parameters:

field - the field to set

Returns:

this instance for chaining
