Constructor Detail

ArrayShortList

public ArrayShortList()
Construct an empty list with the default initial capacity.


ArrayShortList

public ArrayShortList(int initialCapacity)
Construct an empty list with the given initial capacity.

Throws:
IllegalArgumentException - when initialCapacity is negative

ArrayShortList

public ArrayShortList(ShortCollection that)
Constructs a list containing the elements of the given collection, in the order they are returned by that collection's iterator.

Parameters:
that - the non-null collection of shorts to add
Throws:
NullPointerException - if that is null

AbstractShortCollection.addAll(org.apache.commons.collections.primitives.ShortCollection)
Method Detail

get

public short get(int index)
Description copied from interface: ShortList
Returns the value of the element at the specified position within me.

Specified by:
get in interface ShortList
Specified by:
get in class RandomAccessShortList

size

public int size()
Description copied from interface: ShortCollection
Returns the number of elements I contain.

Specified by:
size in interface ShortCollection
Specified by:
size in class RandomAccessShortList

removeElementAt

public short removeElementAt(int index)
Removes the element at the specified position in (optional operation). Any subsequent elements are shifted to the left, subtracting one from their indices. Returns the element that was removed.

Specified by:
removeElementAt in interface ShortList
Overrides:
removeElementAt in class RandomAccessShortList
Parameters:
index - the index of the element to remove
Returns:
the value of the element that was removed
Throws:
UnsupportedOperationException - when this operation is not supported
IndexOutOfBoundsException - if the specified index is out of range

set

public short set(int index,
                 short element)
Replaces the element at the specified position in me with the specified element (optional operation).

Specified by:
set in interface ShortList
Overrides:
set in class RandomAccessShortList
Parameters:
index - the index of the element to change
element - the value to be stored at the specified position
Returns:
the value previously stored at the specified position
Throws:
UnsupportedOperationException - when this operation is not supported
IndexOutOfBoundsException - if the specified index is out of range

add

public void add(int index,
                short element)
Inserts the specified element at the specified position (optional operation). Shifts the element currently at that position (if any) and any subsequent elements to the right, increasing their indices.

Specified by:
add in interface ShortList
Overrides:
add in class RandomAccessShortList
Parameters:
index - the index at which to insert the element
element - the value to insert
Throws:
UnsupportedOperationException - when this operation is not supported
IllegalArgumentException - if some aspect of the specified element prevents it from being added to me
IndexOutOfBoundsException - if the specified index is out of range

ensureCapacity

public void ensureCapacity(int mincap)
Increases my capacity, if necessary, to ensure that I can hold at least the number of elements specified by the minimum capacity argument without growing.


trimToSize

public void trimToSize()
Reduce my capacity, if necessary, to match my current size.
