                        boolean[] a)

Description copied from class: AbstractBooleanList

Add (hopefully quickly) elements to this type-specific list.

This implementation delegates to the analogous method for array fragments.

Specified by:

addElements in interface BooleanList

Overrides:

addElements in class AbstractBooleanList

Parameters:

a - the array containing the elements.

public void addElements(int index,
                        boolean[] a,
                        int offset,
                        int length)

Description copied from class: AbstractBooleanList

Add (hopefully quickly) elements to this type-specific list.

This is a trivial iterator-based implementation. It is expected that implementations will override this method with a more optimized version.

Specified by:

addElements in interface BooleanList

Overrides:

addElements in class AbstractBooleanList

Parameters:

index - the index at which to add elements.

a - the array containing the elements.

offset - the offset of the first element to add.

length - the number of elements to add.

Description copied from interface: BooleanList

Set (hopefully quickly) elements to match the array given.

public void setElements(int index,
                        boolean[] a,
                        int offset,
                        int length)

Description copied from interface: BooleanList

Set (hopefully quickly) elements to match the array given. Sets each in this list to the corresponding elements in the array, as if by

 ListIterator iter = listIterator(index);
 int i = 0;
 while (i < length) {
   iter.next();
   iter.set(a[offset + i++]);
 }
 

However, the exact implementation may be more efficient, taking into account whether random access is faster or not, or at the discretion of subclasses, abuse internals.

Specified by:

setElements in interface BooleanList

index - the index at which to start setting elements.

a - the array containing the elements

offset - the offset of the first element to add.

length - the number of elements to add.
