Type Parameters:

T - Model object type

All Implemented Interfaces:

Direct Known Subclasses:

AbstractDataGridView, DataView, GridView

public abstract class DataViewBase<T>
extends AbstractPageableView<T>

Base class for data views. Data views aim to make it very simple to populate your repeating view from a database by utilizing IDataProvider to act as an interface between the database and the dataview.

Constructor Detail

DataViewBase

public DataViewBase(String id,
                    IDataProvider<T> dataProvider)

Parameters:

id - component id

dataProvider - data provider

Method Detail

internalGetDataProvider

protected final IDataProvider<T> internalGetDataProvider()

Returns:

data provider associated with this view

getItemModels

protected final Iterator<IModel<T>> getItemModels(int offset,
                                                  int count)

Description copied from class: AbstractPageableView

Returns an iterator over models for items in the current page

Specified by:

getItemModels in class AbstractPageableView<T>

Parameters:

offset - index of first item in this page

count - number of items that will be shown in the current page

Returns:

an iterator over models for items in the current page

internalGetItemCount

protected final int internalGetItemCount()

Specified by:

internalGetItemCount in class AbstractPageableView<T>

Returns:

total item count

onDetach

protected void onDetach()

Description copied from class: Component

Called to allow a component to detach resources after use. Overrides of this method MUST call the super implementation, the most logical place to do this is the last line of the override method.

Overrides:

onDetach in class AbstractPageableView<T>

AbstractPageableView.onDetach()
