BitVector32::Section Structure
Represents a section of the vector that can contain an integer number.
Assembly: System (in System.dll)
| Name | Description | |
|---|---|---|
![]() | Mask | Gets a mask that isolates this section within the BitVector32. |
![]() | Offset | Gets the offset of this section from the start of the BitVector32. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object^) | Determines whether the specified object is the same as the current BitVector32::Section object.(Overrides ValueType::Equals(Object^).) |
![]() | Equals(BitVector32::Section) | Determines whether the specified BitVector32::Section object is the same as the current BitVector32::Section object. |
![]() | GetHashCode() | Serves as a hash function for the current BitVector32::Section, suitable for hashing algorithms and data structures, such as a hash table.(Overrides ValueType::GetHashCode().) |
![]() | GetType() | |
![]() | ToString() | Returns a string that represents the current BitVector32::Section.(Overrides ValueType::ToString().) |
![]() ![]() | ToString(BitVector32::Section) | Returns a string that represents the specified BitVector32::Section. |
| Name | Description | |
|---|---|---|
![]() ![]() | Equality(BitVector32::Section, BitVector32::Section) | Determines whether two specified BitVector32::Section objects are equal. |
![]() ![]() | Inequality(BitVector32::Section, BitVector32::Section) | Determines whether two BitVector32::Section objects have different values. |
Use CreateSection to define a new section. A BitVector32::Section is a window into the BitVector32 and is composed of the smallest number of consecutive bits that can contain the maximum value specified in CreateSection. For example, a section with a maximum value of 1 is composed of only one bit, whereas a section with a maximum value of 5 is composed of three bits. You can create a BitVector32::Section with a maximum value of 1 to serve as a Boolean, thereby allowing you to store integers and Booleans in the same BitVector32.
The following code example uses a BitVector32 as a collection of sections.
#using <system.dll> using namespace System; using namespace System::Collections::Specialized; int main() { // Creates and initializes a BitVector32. BitVector32 myBV(0); // Creates four sections in the BitVector32 with maximum values 6, 3, 1, and 15. // mySect3, which uses exactly one bit, can also be used as a bit flag. BitVector32::Section mySect1 = BitVector32::CreateSection( 6 ); BitVector32::Section mySect2 = BitVector32::CreateSection( 3, mySect1 ); BitVector32::Section mySect3 = BitVector32::CreateSection( 1, mySect2 ); BitVector32::Section mySect4 = BitVector32::CreateSection( 15, mySect3 ); // Displays the values of the sections. Console::WriteLine( "Initial values:" ); Console::WriteLine( "\tmySect1: {0}", myBV[ mySect1 ] ); Console::WriteLine( "\tmySect2: {0}", myBV[ mySect2 ] ); Console::WriteLine( "\tmySect3: {0}", myBV[ mySect3 ] ); Console::WriteLine( "\tmySect4: {0}", myBV[ mySect4 ] ); // Sets each section to a new value and displays the value of the BitVector32 at each step. Console::WriteLine( "Changing the values of each section:" ); Console::WriteLine( "\tInitial: \t {0}", myBV ); myBV[ mySect1 ] = 5; Console::WriteLine( "\tmySect1 = 5:\t {0}", myBV ); myBV[ mySect2 ] = 3; Console::WriteLine( "\tmySect2 = 3:\t {0}", myBV ); myBV[ mySect3 ] = 1; Console::WriteLine( "\tmySect3 = 1:\t {0}", myBV ); myBV[ mySect4 ] = 9; Console::WriteLine( "\tmySect4 = 9:\t {0}", myBV ); // Displays the values of the sections. Console::WriteLine( "New values:" ); Console::WriteLine( "\tmySect1: {0}", myBV[ mySect1 ] ); Console::WriteLine( "\tmySect2: {0}", myBV[ mySect2 ] ); Console::WriteLine( "\tmySect3: {0}", myBV[ mySect3 ] ); Console::WriteLine( "\tmySect4: {0}", myBV[ mySect4 ] ); } /* This code produces the following output.
