conn::CSBJavaId Class Reference

class conn::CSBJavaId : public conn::CSBGenericDataType

Generic Data Type representing a MIDlet data owner identified by a Suite Name, Vendor Name, Version and a unique MIDlet Suite Hash. The Suite Hash should be used as the unique identifier for the MIDlet suite.

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]

MIDlet suite name length [4-bytes]

MIDlet suite name [2*length]

MIDlet suite vendor length [4-bytes]

MIDlet suite vendor [2*length]

MIDlet suite version length [4-bytes]

MIDlet suite version [2*length]

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

MIDlet suite hash [2*length]

Byte Structure

TSBDerivedType [4-bytes]

MIDlet suite name length [4-bytes]

MIDlet suite name [2*length]

MIDlet suite vendor length [4-bytes]

MIDlet suite vendor [2*length]

MIDlet suite version length [4-bytes]

MIDlet suite version [2*length]

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

MIDlet suite hash [2*length]

CSBJavaId(const TDesC &, const TDesC &, const TDesC &, const TDesC &)

CSBJavaId	(	const TDesC &	aSuiteName,
		const TDesC &	aSuiteVendor,
		const TDesC &	aSuiteVersion,
		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 & aSuiteName	The name of the MIDlet suite
const TDesC & aSuiteVendor	The name of the vendor of the MIDlet suiet
const TDesC & aSuiteVersion	The version of the MIDlet suite
const TDesC & aSuiteHash	The Java MIDlet suite hash
