Constructor Detail

UnmodifiableBooleanList

public UnmodifiableBooleanList(BooleanList l)

Creates a new unmodifiable list on an existing list. The result is a list whose elements and behaviour is the same as the existing list's except that the new list cannot be modified.

Parameters:

l - the existing list to make unmodifiable.

Throws:

NullPointerException - if l is null.

Method Detail

add

public void add(int index,
                boolean v)

Throws UnsupportedOperationException.

Specified by:

add in interface BooleanList

Parameters:

index - the index at which to add the element. If index == size() the element is appended to this list.

v - the boolean value to add to this list.

Throws:

UnsupportedOperationException - unconditionally.

See Also:

BooleanCollection.add(boolean), BooleanCollection.addAll(BooleanCollection), BooleanList.addAll(int,BooleanCollection)

addAll

public boolean addAll(int index,
                      BooleanCollection c)

Throws UnsupportedOperationException.

Specified by:

addAll in interface BooleanList

Parameters:

index - the index at which to insert the elements of the specified collection. If index == size() the elements are appended to this list.

c - the collection whose elements to add to this list.

Returns:

true if this list was modified as a result of adding the elements of c; returns false otherwise.

Throws:

UnsupportedOperationException - unconditionally.

Returns:

the element at the specified position.

indexOf

public int indexOf(boolean c)

Description copied from interface: BooleanList

Returns the index of the first occurance of a specified element in this list.

Specified by:

indexOf in interface BooleanList

Parameters:

c - the element to find.

Returns:

the index of the first occurance of the specified element in this list; returns -1, if the element is not contained in this list.

indexOf

public int indexOf(int index,
                   boolean c)

Description copied from interface: BooleanList

Returns the index of the first occurance of a specified element in this list after or at a specified index.

Specified by:

indexOf in interface BooleanList

Parameters:

c - the element to find.

index - the index at which to start the search.

Returns:

the index of the last occurance of the specified element in this list; returns -1, if the element is not contained in this list.

lastIndexOf

public int lastIndexOf(int index,
                       boolean c)
