VB.NET Core Classes in a Nutshell

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).
