Constructor Detail

DisplayableHashSet

public DisplayableHashSet()

Constructs a new empty set

DisplayableHashSet

public DisplayableHashSet(java.util.Collection<? extends E> c)

Constructs a new set containing the elements in the specified collection

Parameters:

c - the collection whose elements are to be placed in the set

DisplayableHashSet

public DisplayableHashSet(int initialCapacity)

Constructs a new empty set whose backing HashMap has the specified initial capacity

Parameters:

initialCapacity - the initial capacity

DisplayableHashSet

public DisplayableHashSet(int initialCapacity,
                          float loadFactor)

Constructs a new empty set whose backing HashMap has the specified initial capacity and load factor

Parameters:

initialCapacity - the initial capacity

loadFactor - the load factor

Method Detail

listModel

public javax.swing.ListModel listModel()

Description copied from interface: DisplayableCollection

Create a list model for displaying this collection in a JList. The result of calling toString() is what will actually be displayed for each element. There will be no necessary connection between the order of display and any order in the collection, since this method can be invoked on any collection implementing this interface. (For collections having an inherent order, orderedListModel can be used instead.)
