selection

protected final LinkedHashSet<Object> selection

Deprecated.

Constructor Detail

AbstractSelectionModel

public AbstractSelectionModel()

Deprecated.

Method Detail

isSelected

public boolean isSelected(Object itemId)

Deprecated.

Description copied from interface: Grid.SelectionModel

Checks whether an item is selected or not.

Specified by:

isSelected in interface Grid.SelectionModel

Parameters:

itemId - the item id to check for

Returns:

true if the item is selected

getSelectedRows

public Collection<Object> getSelectedRows()

Deprecated.

Description copied from interface: Grid.SelectionModel

Returns a collection of all the currently selected itemIds.

Specified by:

getSelectedRows in interface Grid.SelectionModel

Returns:

a collection of all the currently selected itemIds

setGrid

public void setGrid(Grid grid)

Deprecated.

Description copied from interface: Grid.SelectionModel

Injects the current Grid instance into the SelectionModel. This method should usually call the extend method of AbstractExtension.

Note: This method should not be called manually.

Specified by:

setGrid in interface Grid.SelectionModel

Parameters:

grid - the Grid in which the SelectionModel currently is, or null when a selection model is being detached from a Grid.

checkItemIdExists

protected void checkItemIdExists(Object itemId)
                          throws IllegalArgumentException

Deprecated.

Sanity check for existence of item id.

Parameters:

itemId - item id to be selected / deselected

Throws:

IllegalArgumentException - if item Id doesn't exist in the container of Grid

checkItemIdsExist

protected void checkItemIdsExist(Collection<?> itemIds)
                          throws IllegalArgumentException

Deprecated.

Sanity check for existence of item ids in given collection.

Parameters:

itemIds - item id collection to be selected / deselected

Throws:

IllegalArgumentException - if at least one item id doesn't exist in the container of Grid

fireSelectionEvent

protected void fireSelectionEvent(Collection<Object> oldSelection,
                                  Collection<Object> newSelection)

Deprecated.

Fires a SelectionEvent to all the SelectionListeners currently added to the Grid in which this SelectionModel is.

Note that this is only a helper method, and routes the call all the way to Grid. A Grid.SelectionModel is not a SelectionEvent.SelectionNotifier

Parameters:

oldSelection - the complete Collection of the itemIds that were selected before this event happened

newSelection - the complete Collection of the itemIds that are selected after this event happened

generateData

public void generateData(Object itemId,
                         Item item,
                         elemental.json.JsonObject rowData)

Deprecated.

Description copied from interface: DataGenerator

Adds data to row object for given item and item id being sent to client.

Specified by:

generateData in interface DataGenerator

Parameters:

itemId - item id of item

item - item being sent to client

rowData - row object being sent to client

destroyData

public void destroyData(Object itemId)

Deprecated.

Description copied from interface: DataGenerator

Informs the DataGenerator that an item id has been dropped and is no longer needed. This method should clean up any unneeded stored data related to the item.

Specified by:

destroyData in interface DataGenerator

Parameters:

itemId - removed item id

getItemId

protected Object getItemId(String rowKey)

Deprecated.

Description copied from class: Grid.AbstractGridExtension

Parameters:

rowKey - the row key for which to retrieve an item id

Returns:

the item id corresponding to key
