  - setSelectedIndices
```
public void setSelectedIndices(int... indices)

    For use with multi-selection mode. Sets the selected indices in this model.
    Note: This may fire multiple selectionChange events. For each "deselected" index, it will fire an event with the (oldIndex, newIndex) being (index, -1) (i.e. selected index changes from the index to -1. And for each newly selected index, it will fire the event with (oldIndex, newIndex) being (-1, index).
    
    Specified by:
    
    setSelectedIndices in interface MultipleSelectionListModel<T>
    
    Parameters:
    
    indices - The indices to select.
    
    Throws:
    
    IllegalArgumentException - If isMultiSelectionMode() is false, and indices length is greater than 1.
    
    Since:
    
    6.0

    setMultiSelectionMode(boolean), isMultiSelectionMode()
  - addSelectedIndices

public void addSelectedIndices(int... indices)
```
    Adds indices to set of selected indices.
    
    Specified by:
    
    addSelectedIndices in interface MultipleSelectionListModel<T>
    
    Parameters:
    
    indices - Indices to add to selected indices.
  - removeSelectedIndices
```
public void removeSelectedIndices(int... indices)
```
    Removes indices from the set of selected indices.
    
    Specified by:
    
    removeSelectedIndices in interface MultipleSelectionListModel<T>

    getSelectedIndices in interface MultipleSelectionListModel<T>
    
    Returns:
    
    Selected indices in increasing order with no duplicates. If there are no selected indices, then this will return a zero-length array.
    
    Since:
    
    6.0
  - isMultiSelectionMode
```
public boolean isMultiSelectionMode()
```
    Checks to see if this list model is in multi-selection mode.
