conn::CSBGenericTransferType Class Reference

class conn::CSBGenericTransferType : public conn::CSBGenericDataType

Generic Transfer Type

This is also a semi-abstract class similar to the CSBGenericDataType in that logically it may only be instantiated by being internalised from a descriptor. This class and classes that derive from it are intended to identify a data transfer to or from a particular data owner.

Byte Structure

All child classes have their data following on from the parent classes so that the parent classes may remain atomic with respect to the structure of their data. The binary structure of this data type inside the descriptor buffer is as follows. Note that the endianness of the data types specified below is determined by the platform and the PC must pack accordingly:

TSBDerivedType [4-bytes]

TDriveNumber [4-bytes]

Constructor & Destructor Documentation

CSBGenericTransferType()

CSBGenericTransferType()[protected]

C++ Constructor. Any derived types must increment iSize in their C++ constructors in order that when CSBGenericDataType::BaseConstructL() is called, the data buffer is initialised to be large enough to accomodate the data stored by the derived type
