Package squidpony.squidmath

Class ShortVLA

java.lang.Object
squidpony.squidmath.ShortVLA
All Implemented Interfaces:
Serializable
public class ShortVLA
extends Object
implements Serializable
A resizable, ordered or unordered short variable-length array. Avoids the boxing that occurs with ArrayList<Short>. If unordered, this class avoids a memory copy when removing elements (the last element is moved to the removed element's position). Used internally by CoordPacker, and unlikely to be used outside of it.
Was called IntArray in libGDX; to avoid confusion with the fixed-length primitive array type, VLA (variable-length array) was chosen as a different name. Also uses short instead of int, of course. Copied from LibGDX by Tommy Ettinger on 10/1/2015.

    • ShortVLA

      public ShortVLA()
      Creates an ordered array with a capacity of 16.

    • ShortVLA

      public ShortVLA​(int capacity)
      Creates an ordered array with the specified capacity.

    • ShortVLA

      public ShortVLA​(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.

    • ShortVLA

      public ShortVLA​(ShortVLA 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.

    • ShortVLA

      public ShortVLA​(short[] 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.

    • ShortVLA

      public ShortVLA​(int[] array)
      Creates a new ordered array containing the elements in the specified array, converted to short. The capacity is set to the number of elements, so any subsequent elements added will cause the backing array to be grown.

    • ShortVLA

      public ShortVLA​(boolean ordered, short[] 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.
