FloatArray

java.lang.Object
- de.topobyte.lightgeom.convexhull.FloatArray

Direct Known Subclasses:

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

- Field Detail
  - items
```
public float[] items
```
  - size
```
public int size
```
  - ordered
```
public boolean ordered
```
- Constructor Detail
  - FloatArray
```
public FloatArray()
```
    Creates an ordered array with a capacity of 16.
  - FloatArray
```
public FloatArray(int capacity)
```
    Creates an ordered array with the specified capacity.
  - FloatArray
```
public FloatArray(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.
  - FloatArray
```
public FloatArray(FloatArray 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.
  - FloatArray
```
public FloatArray(float[] 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.
  - FloatArray
```
public FloatArray(boolean ordered,
                  float[] 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.

    Removes and returns the item at the specified index.
  - removeRange
```
public void removeRange(int start,
                        int end)
```
    Removes the items between the specified indices, inclusive.
  - removeAll
```
public boolean removeAll(FloatArray array)
```
    Removes from this array all of elements contained in the specified array.
    
    Returns:
    
    true if this array was modified.
  - pop
```
public float pop()
```

  - peek
```
public float peek()
```
    Returns the last item.

```
public float first()
```
    Returns the first item.
  - clear
```
public void clear()
```
  - shrink
```
public float[] 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 float[] 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
  - setSize
```
public float[] setSize(int newSize)
```
    Sets the array size, leaving any values beyond the current size undefined.

```
protected float[] resize(int newSize)
```
  - sort
```
public void sort()
```
  - reverse
```
public void reverse()
```
  - 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.
  - toArray
```
public float[] toArray()
```
  - hashCode
```
public int hashCode()
```
  - equals
```
public boolean equals(Object object)
```
  - equals
```
