Method Detail

getShownRecords

public Set<RecordHolder> getShownRecords()

Description copied from interface: UIComponentShowingRecords

Lists record instances currently displayed in the component's selection.

Used for validation purposes, to match record-level validation errors to components. E.g. the validation error may be displayed on a Table if the table is currently displaying given record.

Some rules for the method:

• The table component should return only records which are currently displayed. For example, the paging table should return only records currently being shown on the current table page.
• Repeater should return all records (there is no paging)
• Calendar should only return records which are displayed in the current date range.
• Combobox should not return anything. Theoretically it could return currently selected record, but this record is accessible via the BINDING field, therefore it is not necessary to return this information through this method.
• Generally, the method should return data for Tables, Tree tables, Repeaters and Calendars only.

Specified by:

getShownRecords in interface UIComponentShowingRecords

Returns:

record instances currently displayed in the component's selection. May return null or empty list. The list may be immutable.

initChildren

public void initChildren(boolean isFirstLoad)

Description copied from interface: UIRefreshHandler

Should initialize all visible child components. See UIComponents.initChildren(java.util.List, boolean).

Specified by:

initChildren in interface UIRefreshHandler

Parameters:

isFirstLoad - value of field UIFieldNames.IS_FIRST_LOAD of the created init event

registerChildren

public void registerChildren()

Description copied from interface: UIRefreshHandler

Should register all child components in the screen. See UIScreen.registerUIComponent(UIComponent).

Specified by:

registerChildren in interface UIRefreshHandler

unregisterChildren

public void unregisterChildren()

Description copied from interface: UIRefreshHandler

Should unregister all child components in the screen. See UIScreen.unregisterUIComponent(UIComponent).

Specified by:

unregisterChildren in interface UIRefreshHandler

refresh

public void refresh()

Description copied from interface: UIComponent

This method is called from LSPS rendering engine. It should load all information needed from component definition record holder and apply them accordingly.

Note that this method should not attempt to apply any hints - hints are applied automatically after the component is refreshed. You however may read the hints value here - it is guaranteed that you will receive freshly updated hint value by reading UIComponentData.getHints().

Specified by:

refresh in interface UIComponent

updateContextFor

public void updateContextFor(UIComponentScope scope)

Description copied from interface: UIComponentWithCustomScopes

Updates context with all necessary values for the given scope.

Specified by:

updateContextFor in interface UIComponentWithCustomScopes

getComponentData

public UIComponentData getComponentData()

Description copied from interface: UIComponent

Returns the component definition (LSPS RecordHolder instance which is subtype of "ui::Component") associated with this Vaadin component.

Specified by:

getComponentData in interface UIComponent

Returns:

component definition. The definition record instance must be present in root scope (screen context).

getRefreshedComponents

public Set<UIComponent> getRefreshedComponents()

Specified by:

getRefreshedComponents in interface UIRefreshHandler

Returns:

set of components refreshed during last refresh call

toString

public String toString()

Overrides:

toString in class Object

getWidget

public com.vaadin.ui.AbstractComponent getWidget()

Description copied from interface: UIComponent

Returns the Vaadin widget which implements the UI part of this component.

Specified by:

getWidget in interface UIComponent

Returns:

the widget, not null.
