Method Detail

getSelectionCount

int getSelectionCount()

Returns the number of objects in this selection.

Returns:

the number of objects in this ILcdSelection.

selectedObjects

Enumeration<T> selectedObjects()

Returns the objects in this selection.

Returns:

the objects currently in this ILcdSelection.

isSelected

boolean isSelected(Object aObject)

Checks whether the given Object is currently in the set of selected objects.

Parameters:

aObject - the Object to be checked.

Returns:

true if the Object is in this ILcdSelection, false otherwise.

getSelectedObjects

default List<T> getSelectedObjects()

Returns a List of the selected objects.

Returns:

an unmodifiable List of the objects in this ILcdSelection

2018.0

addSelectionListener

void addSelectionListener(ILcdSelectionListener<T> aSelectionListener)

Adds a listener to this selection. In case you need to register a listener which keeps a reference to an object with a shorter life-time than this ILcdSelection, you can use a ALcdWeakSelectionListener instance as selection listener.

Parameters:

aSelectionListener - the ILcdSelectionListener to be added.

removeSelectionListener

void removeSelectionListener(ILcdSelectionListener<T> aSelectionListener)

Removes an ILcdSelectionListener from this ILcdSelection.

Parameters:

aSelectionListener - the ILcdSelectionListener to be removed.
