Type Parameters:

T - Type of the Beans in the backing data source.

All Implemented Interfaces:

ILayer, ILayerListener, IPersistable

public class SortHeaderLayer<T>
extends AbstractLayerTransform
implements IPersistable

Method Details

getConfigLabelsByPosition

public LabelStack getConfigLabelsByPosition(int columnPosition,
 int rowPosition)

Description copied from interface: ILayer

Returns the config labels for the cell at the given coordinates. Needed to retrieve the corresponding configurations out of the IConfigRegistry.

Specified by:

getConfigLabelsByPosition in interface ILayer

Overrides:

getConfigLabelsByPosition in class AbstractLayerTransform

Parameters:

columnPosition - The column position of the cell.

rowPosition - The row position of the cell.

Returns:

adds a special configuration label to the stack taking into account the following:

1. Is the column sorted ?
2. What is the sort order of the column

A special painter is registered against the above labels to render the sort arrows

getSortModel

public ISortModel getSortModel()

Returns:

The ISortModel that is used to handle the sorting of the underlying data.

getProvidedLabels

public Collection<String> getProvidedLabels()

Specified by:

getProvidedLabels in interface ILayer

Overrides:

getProvidedLabels in class AbstractLayer

Returns:

The collection of labels that are provided by this layer.
