Class CSdpAttrValueUint

class CSdpAttrValueUint : public CSdpAttrValue;

Description

A unsigned integer value of an attribute.

The value can be up to 128 bits in size. You need to choose to use either CSdpAttrValueUint::Uint()const for up to 32 bit size, CSdpAttrValue::Uint64(TUint64 &)const for up to 64 bit size or CSdpAttrValue::Uint128(TUint64 &,TUint64 &)const for up to 128 bit size. The size can be found using CSdpAttrValueUint::DataSize()const. If the incorrect function is used the code will panic.

Derivation

• CBase - Base class for all classes to be instantiated on the heap.

• CSdpAttrValue - Base class for classes that encapsulate SDP attributes values.

• CSdpAttrValueUint - A unsigned integer value of an attribute.

virtual ~CSdpAttrValueUint();

Description

Destructor.

IMPORT_C static CSdpAttrValueUint* NewUintL(const TDesC8 &aUint);

Description

Allocates and constructs a new CSdpAttrValueUint object.

Parameters

const TDesC8 &aUint Buffer containing an unsigned integer value for the attribute

Return value

CSdpAttrValueUint * New CSdpAttrValueUint object

IMPORT_C void SetUintValue(const TDesC8 &aValue);

Description

Replaces the current value.

Parameters

const TDesC8 &aValue The new value. The provided value must not exceed KSdpMaxUintSize.

Panic codes

USER 23 if the supplied value is too long.

virtual TSdpElementType Type() const;

Description

Gets the attribute type.

Return value

TSdpElementType Attribute type. Always ETypeUint.

virtual TUint DataSize() const;

Description

Gets the size of the attribute.

Return value

TUint Size of the attribute in bytes

virtual TUint Uint() const;

Description

Gets the value as an unsigned integer type.

The size of the unsigned integer should be checked with CSdpAttrValueUint::DataSize()const before calling.

Return value

TUint Attribute value

virtual TBool DoesIntFit() const;

Description

Tests if the attribute can be stored in an integer value.

Return value

TBool True if the attribute can be stored in an integer value

virtual const TPtrC8 Des() const;

Description

Gets the value as a data buffer.

Return value

const TPtrC8 Attribute value
