IntArray (libGDX Core 1.2.0 API)

java.lang.Object
- com.badlogic.gdx.utils.IntArray

```
public class IntArray
extends Object
```
A resizable, ordered or unordered int array. Avoids the boxing that occurs with ArrayList. If unordered, this class avoids a memory copy when removing elements (the last element is moved to the removed element's position).

```
  - size
```
public int size
```
  - ordered
```
public boolean ordered
```
- Constructor Detail
  - IntArray
```
public IntArray()
```
    Creates an ordered array with a capacity of 16.
  - IntArray
```
public IntArray(int capacity)
```
    Creates an ordered array with the specified capacity.
  - IntArray
```
public IntArray(boolean ordered,
        int capacity)
```
    Parameters:
    ordered - If false, methods that remove elements may change the order of other elements in the array, which avoids a memory copy.
    capacity - Any elements added beyond this will cause the backing array to be grown.
  - IntArray
```
public IntArray(IntArray array)
```
    Creates a new array containing the elements in the specific array. The new array will be ordered if the specific array is ordered. The capacity is set to the number of elements, so any subsequent elements added will cause the backing array to be grown.
  - IntArray
```
public IntArray(int[] array)
```
    Creates a new ordered array containing the elements in the specified array. The capacity is set to the number of elements, so any subsequent elements added will cause the backing array to be grown.
  - IntArray
```
public IntArray(boolean ordered,
        int[] array,
        int startIndex,
        int count)
```
    Creates a new array containing the elements in the specified array. The capacity is set to the number of elements, so any subsequent elements added will cause the backing array to be grown.
    
    Parameters:
    ordered - If false, methods that remove elements may change the order of other elements in the array, which avoids a memory copy.

public int removeIndex(int index)
```
    Removes and returns the item at the specified index.
  - removeRange
```
public void removeRange(int start,
               int end)
```
    Removes the items at the specified indices, inclusive.
  - removeAll
```
public boolean removeAll(IntArray array)
```
    Removes from this array all of elements contained in the specified array.
    
    Returns:
    true if this array was modified.
  - pop
```
public int pop()
```
    Removes and returns the last item.
  - peek
```
public int peek()
```
    Returns the last item.
  - first
```
public int first()
```
    Returns the first item.
  - clear
```
public void clear()
```
  - shrink
```
public int[] shrink()
```
    Reduces the size of the backing array to the size of the actual items. This is useful to release memory when many items have been removed, or if it is known that more items will not be added.
    
    Returns:
    items
  - ensureCapacity
```
public int[] ensureCapacity(int additionalCapacity)
```
    Increases the size of the backing array to accommodate the specified number of additional items. Useful before adding many items to avoid multiple backing array resizes.
    
    Returns:
    items
  - sort
```
public void sort()
```
  - reverse
```
public void reverse()
```
  - shuffle
```
public void shuffle()
```
  - truncate
```
public void truncate(int newSize)
```
    Reduces the size of the array to the specified size. If the array is already smaller than the specified size, no action is taken.
  - random
```
public int random()
```
    Returns a random item from the array, or zero if the array is empty.
  - toArray
```
public int[] toArray()
```
  - equals
```
public boolean equals(Object object)
```
    Overrides:
    
    equals in class Object
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - toString
```
public String toString(String separator)
```
  - with
```
public static IntArray with(int... array)
