public class IntegerList
extends AbstractList<Integer>
implements RandomAccess, Serializable, Cloneable
A list of unsigned integer values. This class packs the values in the minimal amount of bits
required for storing unsigned integers of the given maximal value.
This class is not thread-safe. Synchronizations (if wanted) are user's responsibility.

Constructor Details
-
IntegerList
public IntegerList(int initialCapacity, int maximalValue) Creates an initially empty list with the given initial capacity.- Parameters:
initialCapacity- the initial capacity.maximalValue- the maximal value to be allowed, inclusive.
-
IntegerList
public IntegerList(int initialCapacity, int maximalValue, boolean fill) Creates a new list with the given initial size. The value of all elements are initialized to 0.- Parameters:
initialCapacity- the initial capacity.maximalValue- the maximal value to be allowed, inclusive.fill- iftrue, the initial size is set to the initial capacity with all values set to 0.

Method Details
-
maximalValue
public int maximalValue()Returns the maximal value that can be stored in this list. May be slightly higher than the value given to the constructor.- Returns:
- the maximal value, inclusive.
-
size
public int size()Returns the current number of values in this list.- Specified by:
sizein interfaceCollection<Integer>- Specified by:
sizein interfaceList<Integer>- Specified by:
sizein classAbstractCollection<Integer>- Returns:
- the number of values.
-
resize
public void resize(int size) Sets the list size to the given value. If the new size is lower than previous size, then the elements after the new size are discarded. If the new size is greater than the previous one, then the extra elements are initialized to 0.- Parameters:
size- the new size.- See Also:
-
fill
public void fill(int value) Fills the list with the given value. Every existing values are overwritten from index 0 inclusive up tosize()exclusive.- Parameters:
value- the value to set.
-
clear
public void clear()Discards all elements in this list.- Specified by:
clearin interfaceCollection<Integer>- Specified by:
clearin interfaceList<Integer>- Overrides:
clearin classAbstractList<Integer>
-
add
Adds the given element to this list.- Specified by:
addin interfaceCollection<Integer>- Specified by:
addin interfaceList<Integer>- Overrides:
addin classAbstractList<Integer>- Parameters:
value- the value to add.- Returns:
- always
true. - Throws:
NullPointerException- if the given value is null.IllegalArgumentException- if the given value is out of bounds.
-
addInt
Adds the given element as theintprimitive type.- Parameters:
value- the value to add.- Throws:
IllegalArgumentException- if the given value is out of bounds.- See Also:
-
get
Returns the element at the given index.- Specified by:
getin interfaceList<Integer>- Specified by:
getin classAbstractList<Integer>- Parameters:
index- the element index.- Returns:
- the value at the given index.
- Throws:
IndexOutOfBoundsException- if the given index is out of bounds.
-
getInt
Returns the element at the given index as theintprimitive type.- Parameters:
index- the element index.- Returns:
- the value at the given index.
- Throws:
IndexOutOfBoundsException- if the given index is out of bounds.
-
set
Sets the element at the given index.- Specified by:
setin interfaceList<Integer>- Overrides:
setin classAbstractList<Integer>- Parameters:
index- the element index.value- the value at the given index.- Returns:
- the previous value at the given index.
- Throws:
IndexOutOfBoundsException- if the given index is out of bounds.IllegalArgumentException- if the given value is out of bounds.NullPointerException- if the given value is null.
-
setInt
Sets the element at the given index as theintprimitive type.- Parameters:
index- the element index.value- the value at the given index.- Throws:
IndexOutOfBoundsException- if the given index is out of bounds.IllegalArgumentException- if the given value is out of bounds.
-
remove
Removes the element at the given index.- Specified by:
removein interfaceList<Integer>- Overrides:
removein classAbstractList<Integer>- Parameters:
index- the index of the element to remove.- Returns:
- the previous value of the element at the given index.
- Throws:
IndexOutOfBoundsException- if the given index is out of bounds.
-
removeLast
Retrieves and remove the last element of this list.- Specified by:
removeLastin interfaceList<Integer>- Specified by:
removeLastin interfaceSequencedCollection<Integer>- Returns:
- the tail of this list.
- Throws:
NoSuchElementException- if this list is empty.
-
removeRange
protected void removeRange(int lower, int upper) Removes all values in the given range of index. Shifts any succeeding elements to the left (reduces their index).- Overrides:
removeRangein classAbstractList<Integer>- Parameters:
lower- index of the first element to remove, inclusive.upper- index after the last element to be removed.
-
occurrence
public int occurrence(int value) Returns the occurrence of the given value in this list.- Parameters:
value- the value to search for.- Returns:
- the number of time the given value occurs in this list.
-
iterator
Returns an iterator over the elements in this list in increasing index order. The iterator is fail-fast and supports the remove operation. -
spliterator
Returns an spliterator over the elements in this list in increasing index order. The iterator is fail-fast.- Specified by:
spliteratorin interfaceCollection<Integer>- Specified by:
spliteratorin interfaceIterable<Integer>- Specified by:
spliteratorin interfaceList<Integer>- Returns:
- spliterator over the integer values in this list.
- Since:
- 1.0
-
stream
Returns a stream of integers with thisIntegerListas its source. This method is similar toCollection.stream(), but does not box the values. The returned stream is fail-fast, meaning that any modification to the list while using the stream will cause aConcurrentModificationExceptionto be thrown.The default implementation creates a parallel or sequential stream from
spliterator().- Parameters:
parallel-truefor a parallel stream, orfalsefor a sequential stream.- Returns:
- a stream of values in this list as primitive types.
- Since:
- 1.0
-
trimToSize
public void trimToSize()Trims the capacity of this list to be its current size.- See Also:
-
equals
Compares the content of this list with the given object. This method overrides thedefault implementationfor performance reasons.- Specified by:
equalsin interfaceCollection<Integer>- Specified by:
equalsin interfaceList<Integer>- Overrides:
equalsin classAbstractList<Integer>- Parameters:
other- the other object to compare with this list.- Returns:
trueif both object are equal.- Since:
- 1.1
-
clone
Returns a clone of this list.
