Esempio

Nell'esempio di codice seguente viene utilizzato un BitVector32 oggetto come raccolta di sezioni.

#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.

Commenti

Usare CreateSection per definire una nuova sezione. Un BitVector32.Section oggetto è una finestra nell'oggetto BitVector32 e è costituito dal numero più piccolo di bit consecutivi che possono contenere il valore massimo specificato in CreateSection. Ad esempio, una sezione con un valore massimo di 1 è composta da un solo bit, mentre una sezione con un valore massimo di 5 è composta da tre bit. È possibile creare un BitVector32.Section oggetto con un valore massimo pari a 1 per fungere da valore booleano, consentendo così di archiviare numeri interi e booleani nello stesso BitVector32.

Proprietà

Mask	Ottiene una maschera che isola la sezione all'interno della struttura BitVector32.
Offset	Ottiene l'offset della sezione a partire dall'inizio della struttura BitVector32.

Metodi

Equals(BitVector32+Section)	Determina se l'oggetto BitVector32.Section specificato corrisponde all'oggetto BitVector32.Section corrente.
Equals(Object)	Determina se l'oggetto specificato corrisponde all'oggetto BitVector32.Section corrente.
GetHashCode()	Viene usato come funzione hash per l'oggetto BitVector32.Section corrente, adatto per algoritmi hash e strutture di dati, ad esempio una tabella hash.
ToString()	Restituisce una stringa che rappresenta l'oggetto BitVector32.Section corrente.
ToString(BitVector32+Section)	Restituisce una stringa che rappresenta l'oggetto BitVector32.Section specificato.

Operatori

Equality(BitVector32+Section, BitVector32+Section)	Determina se due oggetti BitVector32.Section specificati sono uguali.
Inequality(BitVector32+Section, BitVector32+Section)	Determina se due oggetti BitVector32.Section hanno valori diversi.
