public abstract class AbstractReferenceBigList<K>
extends AbstractReferenceCollection<K>
implements ReferenceBigList<K>, it.unimi.dsi.fastutil.Stack<K>

An abstract class providing basic methods for big lists implementing a type-specific big list interface.

Most of the methods in this class are optimized with the assumption that the List will have have constant-time random access. If this is not the case, you should probably at least override listIterator(long) and the xAll() methods (such as addAll(long, java.util.Collection<? extends K>)) with a more appropriate iteration scheme. Note the subList(long, long) method is cognizant of random-access or not, so that need not be reimplemented.

removeElements

public void removeElements(long from,
long to)

Removes (hopefully quickly) elements of this type-specific big list.

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

Specified by:

removeElements in interface ReferenceBigList<K>

Parameters:

from - the start index (inclusive).

to - the end index (exclusive).

addElements

public void addElements(long index,
K[][] a,
long offset,
long length)

Add (hopefully quickly) elements to this type-specific big 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 ReferenceBigList<K>

Parameters:

index - the index at which to add elements.

a - the big array containing the elements.

offset - the offset of the first element to add.

length - the number of elements to add.

addElements

public void addElements(long index,
K[][] a)

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

Specified by:

Parameters:

index - the index at which to add elements.

a - the big array containing the elements.

Implementation Specification:

This implementation delegates to the analogous method for big-array fragments.

public void getElements(long from,
java.lang.Object[][] a,
long offset,
long length)

Copies (hopefully quickly) elements of this type-specific big list into the given big array.

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

Specified by:

getElements in interface ReferenceBigList<K>

Parameters:

from - the start index (inclusive).

a - the destination big array.

offset - the offset into the destination big array where to store the first element copied.

length - the number of elements to be copied.

setElements

public void setElements(long index,
K[][] a,
long offset,
long length)

Description copied from interface: ReferenceBigList

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);
 long i = 0;
 while (i < length) {
   iter.next();
   iter.set(BigArrays.get(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 ReferenceBigList<K>

Parameters:

index - the index at which to start setting elements.

a - the big array containing the elements.

offset - the offset of the first element to add.

length - the number of elements to add.
