Public Overrides Function Equals (o As Object) As Boolean
Parameters
- o
- Object
Het object dat moet worden vergeleken met de huidige BitVector32.
Retouren
trueals het opgegeven object gelijk is aan de BitVector32; anders. false

Opmerkingen
Het object o wordt als gelijk beschouwd als het BitVector32 type compatibel is met het BitVector32 type o en of de waarde o gelijk is aan de waarde van Data.
Deze methode is een O(1)-bewerking.
