Description
Méthodes responsables de lire jusqu'à Count fixe le nombre d'octets SizeOf(Buffer) du flux vers Buffer.
Utilisez ReadBufferData pour lire exactement le Count fixe ou le nombre d'octets SizeOf(Buffer) du flux vers un Buffer typé. ReadBufferData déclenche une exception EReadError si ReadBufferData ne peut pas lire exactement le nombre d'octets spécifié.
ReadBufferData fonctionne en utilisant les algorithmes suivants :
- Si ReadBufferData ne contient pas le paramètre
Count, ReadBufferData essaie de lire le nombre d'octetsSizeOf(Buffer), puis avance la position en cours dans le flux du nombre d'octets transférés. Si le nombre d'octets transférés n'est pas= SizeOf(Buffer), ReadBufferData déclenche une exception EReadError. - Si ReadBufferData contient le paramètre
Count, ReadBufferData appelle ReadData pour lire les octetsCount. Si le nombre d'octets transférés signalé n'est pas égal àCount, ReadBufferData déclenche une exception EReadError.
ReadBufferData appelle ReadData pour effectuer la lecture réelle.
