set
in interfaceLongList
- Overrides:
set
in classAbstractLongList

size
public int size()
- Specified by:
size
in interfacejava.util.Collection<java.lang.Long>
- Specified by:
size
in interfacejava.util.List<java.lang.Long>
- Specified by:

getElements
public void getElements(int from, long[] a, int offset, int length)
Description copied from class:AbstractLongList
Copies (hopefully quickly) elements of this type-specific list into the given 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 interfaceLongList
- Overrides:
getElements
in classAbstractLongList
- Parameters:
from
- the start index (inclusive).a
- the destination array.offset
- the offset into the destination array where to store the first element copied.length
- the number of elements to be copied.
-
removeElements
public void removeElements(int from, int to)
Description copied from class:AbstractLongList
Removes (hopefully quickly) elements of this type-specific list.This is a trivial iterator-based based implementation. It is expected that implementations will override this method with a more optimized version.
- Specified by:
removeElements
in interfaceLongList
- Overrides:
removeElements
in classAbstractLongList
- Parameters:
from
- the start index (inclusive).to
- the end index (exclusive).
-
addElements
public void addElements(int index, long[] a, int offset, int length)
Description copied from class:AbstractLongList
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 interfaceLongList
- Overrides:
addElements
in classAbstractLongList
- 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(int index, long[] a, int offset, int length)
Description copied from interface:LongList
Set (hopefully quickly) elements to match the array given. Sets each in this list to the corresponding elements in the array, as if byListIterator 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 interfaceLongList
- Overrides:
setElements
in classAbstractLongList
- Parameters:
index
- the index at which to start setting elements.a
- the array containing the elementsoffset
- the offset of the first element to add.length
- the number of elements to add.
