TCardinality Class Reference

class TCardinality

Compact stream format for positive integer values in the range 0 to 536,870,911 ((2^29)-1). Values in the range 0-127 are stored in a single byte, 128-16383 in two bytes and other values in 4 bytes.

The class provides conversion to and from TInt, and both externalization and internalization functions. It is used to significant effect within Symbian code.

Constructor & Destructor Documentation

TCardinality()

TCardinality()[inline]

TCardinality(TInt)

TCardinality(TIntaCount)[inline]

Constructs the object with the specified value.

Parameters

TInt aCountThe value for this object.

Member Functions Documentation

ExternalizeL(RWriteStream &)

IMPORT_C voidExternalizeL(RWriteStream &aStream)const

Externalises this object to a write stream.

The existence of this function means that the standard templated operator<<() can be used to externalise objects of this class.

operator<<()

Parameters

RWriteStream & aStreamStream to which the object should be externalised.

InternalizeL(RReadStream &)

IMPORT_C voidInternalizeL(RReadStream &aStream)

Internalizes this object from a read stream.

The existence of this function means that the standard templated operator>>() can be used to internalise objects of this class.

operator>>()

Parameters

RReadStream & aStreamStream store from which the objet is to be internalised.

__DbgChkRange(TInt)

IMPORT_C void__DbgChkRange(TIntaCount)[private, static]

Parameters

TInt aCount

operator TInt()

operator TInt()const [inline]
