Beschreibung
Methoden, die für das Einlesen der festgelegten Byte-Anzahl Count oder SizeOf(Buffer) aus dem Stream in Buffer zuständig sind.
Mit ReadBufferData lesen Sie exakt die festgelegte Byte-Anzahl Count oder SizeOf(Buffer) aus dem Stream in einen typisierten Buffer ein. ReadBufferData löst eine EReadError-Exception aus, wenn ReadBufferData die angegebene Byte-Anzahl nicht exakt lesen kann.
ReadBufferData arbeitet mit den folgenden Algorithmen:
- Wenn ReadBufferData den Parameter
Countnicht enthält, dann versucht ReadBufferData, die Byte-AnzahlSizeOf(Buffer)zu lesen und setzt dann die aktuelle Position im Stream um die Anzahl der übertragenen Bytes nach vorne. Wenn die Anzahl der übertragenen Bytes nicht= SizeOf(Buffer)ist, dann löst ReadBufferData eine EReadError-Exception aus. - Wenn ReadBufferData den Parameter
Countenthält, dann ruft ReadBufferData ReadData auf, um dieCountByte zu lesen. Wenn die gemeldete Anzahl von übertragenen Bytes nicht gleichCountist, dann löst ReadBufferData eine EReadError-Exception aus.
ReadBufferData ruft für die eigentliche Leseoperation ReadData auf.
