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. |
