conn::CSBJavaTransferType Class Reference

class conn::CSBJavaTransferType : public conn::CSBGenericTransferType

The Java Transfer Type identifies types of data belonging to particular MIDlet suites (identified by the Suite Hash)

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]

TJavaTransferType [4-bytes]

MIDlet suite hash length [4-bytes] (should be 32)

MIDlet suite hash [2*length]

The Java Transfer Type identifies types of data belonging to particular MIDlet suites (identified by the Suite Hash)

Byte Structure

TSBDerivedType [4-bytes]

TDriveNumber [4-bytes]

TJavaTransferType [4-bytes]

MIDlet suite hash length [4-bytes] (should be 32)

MIDlet suite hash [2*length]

(

)

[private]

C++ Constructor

CSBJavaTransferType(const TDesC &)

CSBJavaTransferType

(

const TDesC &

aSuiteHash

)

[private]

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

Parameters

const TDesC & aSuiteHash
