Constructor Summary

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

ArrayByteList(org.apache.commons.collections.primitives.ByteCollection that)
Constructs a list containing the elements of the given collection, in the order they are returned by that collection's iterator.

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

Method Summary

void	add(int index, byte element) Inserts the specified element at the specified position (optional operation).
void	clear() Removes all my elements (optional operation).
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.
byte	get(int index) Returns the value of the element at the specified position within me.
byte	removeElementAt(int index) Removes the element at the specified position in (optional operation).
byte	set(int index, byte element) Replaces the element at the specified position in me with the specified element (optional operation).
int	size() Returns the number of elements I contain.
void	trimToSize() Reduce my capacity, if necessary, to match my current size.

Constructor Detail

ArrayByteList

public ArrayByteList()

Construct an empty list with the default initial capacity.

ArrayByteList

public ArrayByteList(int initialCapacity)

Construct an empty list with the given initial capacity.

Throws:

IllegalArgumentException - when initialCapacity is negative

ArrayByteList

public ArrayByteList(org.apache.commons.collections.primitives.ByteCollection 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 bytes to add

Throws:

NullPointerException - if that is null

AbstractByteCollection.addAll(org.apache.commons.collections.primitives.ByteCollection)

Method Detail

get

public byte get(int index)

Description copied from interface: ByteList

Returns the value of the element at the specified position within me.

Specified by:

get in interface ByteList

Specified by:

get in class RandomAccessByteList

Parameters:

index - the index of the element to return

Returns:

the value of the element at the specified position

size

public int size()

Description copied from interface: ByteCollection

Returns the number of elements I contain.

Specified by:

size in interface ByteCollection

Specified by:

size in class RandomAccessByteList

Returns:

the number of elements I contain

removeElementAt

public byte 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 ByteList

Overrides:

removeElementAt in class RandomAccessByteList

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 byte set(int index,
                byte element)

Replaces the element at the specified position in me with the specified element (optional operation).

Specified by:

set in interface ByteList

Overrides:

set in class RandomAccessByteList

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,
                byte 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 ByteList

Overrides:

add in class RandomAccessByteList

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

clear

public void clear()

Description copied from interface: ByteCollection

Removes all my elements (optional operation). I will be empty after this method successfully returns.

Specified by:

clear in interface ByteCollection

Overrides:

clear in class AbstractByteCollection

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.
