removeElements

public void removeElements(int from, int to)

Description copied from class: AbstractShortList

Removes (hopefully quickly) elements of 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:

Parameters:

from - the start index (inclusive).

to - the end index (exclusive).

Description copied from class: AbstractShortList

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

This implementation delegates to the analogous method for array fragments.

Specified by:

addElements in interface ShortList

Overrides:

addElements in class AbstractShortList

Parameters:

index - the index at which to add elements.

a - the array containing the elements.

addElements

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

Description copied from class: AbstractShortList

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 ShortList

Overrides:

addElements in class AbstractShortList

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.

setElements

public void setElements(short[] a)

Description copied from interface: ShortList

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

Specified by:

setElements in interface ShortList

Parameters:

a - the array containing the elements.

setElements

public void setElements(int index, short[] a)

Description copied from interface: ShortList

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

Specified by:

setElements in interface ShortList

Parameters:

index - the index at which to start setting elements.

a - the array containing the elements.

setElements

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

Description copied from interface: ShortList

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 ShortList

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.
