Field Detail

EMPTY_LIST

public static final BooleanLists.EmptyList EMPTY_LIST
An empty list (immutable). It is serializable and cloneable.

The class of this objects represent an abstract empty list that is a sublist of any type of list. Thus, EMPTY_LIST may be assigned to a variable of any (sorted) type-specific list.

Method Detail

singleton

public static BooleanList singleton(boolean element)
Returns a type-specific immutable list containing only the specified element. The returned list is serializable and cloneable.

Parameters:
element - the only element of the returned list.
Returns:
a type-specific immutable list containing just element.

singleton

public static BooleanList singleton(java.lang.Object element)
Returns a type-specific immutable list containing only the specified element. The returned list is serializable and cloneable.

Parameters:
element - the only element of the returned list.
Returns:
a type-specific immutable list containing just element.

synchronize

public static BooleanList synchronize(BooleanList l)
Returns a synchronized type-specific list backed by the given type-specific list.

Parameters:
l - the list to be wrapped in a synchronized list.
Returns:
a synchronized view of the specified list.

Collections.synchronizedList(List)

synchronize

public static BooleanList synchronize(BooleanList l,
                                      java.lang.Object sync)
Returns a synchronized type-specific list backed by the given type-specific list, using an assigned object to synchronize.

Parameters:
l - the list to be wrapped in a synchronized list.
sync - an object that will be used to synchronize the access to the list.
Returns:
a synchronized view of the specified list.

Collections.synchronizedList(List)

unmodifiable

public static BooleanList unmodifiable(BooleanList l)
Returns an unmodifiable type-specific list backed by the given type-specific list.

Parameters:
l - the list to be wrapped in an unmodifiable list.
Returns:
an unmodifiable view of the specified list.
