BitVector32

Synopsis

This structure defines a lightweight bit vector that can store booleans and 16-bit integers in a 32-bit structure. Sections hold single 16-bit integer values and are the building blocks of a BitVector32. Sections are created with CreateSection( ). Each section is constructed with a maximum value for the integer it can hold. Except for the initial section, each subsequent section must provide a reference to the previous section in addition to the maximum value.

The indexer takes two forms. When indexed by a section name, that section’s value can be set or retrieved. When indexed by an integer that specifies a bit in the vector, you can determine whether that bit is set or not (true or false).

public struct BitVector32 {
// Public Conastructors
   public BitVector32(BitVector32 value);
   public BitVector32(int data);
// Public Instance Properties
   public int Data{get; }
   public int this(Section section)){set; get; }
   public bool this[int bit]{set; get; }
// Public Static Methods
   public static int CreateMask( );
   public static int CreateMask(int previous);
   public static Section CreateSection(short maxValue);
   public static Section CreateSection(short maxValue, Section previous);
   public static string ToString(BitVector32 value);
