Class SingleListSelectionPolicy<V>

java.lang.Object
  com.guiseframework.model.AbstractListSelectionPolicy<V>
      com.guiseframework.model.SingleListSelectionPolicy<V>

Type Parameters:

V - The type of values contained in the select model.

All Implemented Interfaces:

ListSelectionPolicy<V>

public final class SingleListSelectionPolicy<V>
extends AbstractListSelectionPolicy<V>

An implementation of a selection strategy for a select model allowing only a single selection at a time. This class is marked final because it demarcates certain selection semantics that, if they can be assumed, may be offloaded to a component's view in certain circumstances. This class is thread-safe, and assumes that the corresponding select model is thread-safe, synchronized on itself.

Method Detail

getSetSelectedIndices

public int[] getSetSelectedIndices(ListSelectModel<V> selectModel,
                                   int[] indices)

Determines which requested indices may be set as the selection. This implementation only allows the first index to be set.

Specified by:

getSetSelectedIndices in interface ListSelectionPolicy<V>

Overrides:

getSetSelectedIndices in class AbstractListSelectionPolicy<V>

Parameters:

selectModel - The model containing the values to be selected.

indices - The requested indices to set as the selection.

Returns:

The indices that can be set as the selection.

getAddSelectedIndices

public int[] getAddSelectedIndices(ListSelectModel<V> selectModel,
                                   int[] indices)

Determines which requested indices may be added to the selection. This implementation allows the addition of all requested indices.

Specified by:

getAddSelectedIndices in interface ListSelectionPolicy<V>

Overrides:

getAddSelectedIndices in class AbstractListSelectionPolicy<V>

Parameters:

selectModel - The model containing the values to be selected.

indices - The requested indices to add to the selection.

Returns:

The indices that can be added to the selection.
