IMPORT_C static CX520AttributeTypeAndValue* NewL(const TDesC8 &aBinaryData);

Description

Creates a new CX520AttributeTypeAndValue object from the specified buffer containing the encoded binary representation.

Initialises the object from its encoded binary form into an internal representation.

Parameters

Return value

IMPORT_C static CX520AttributeTypeAndValue* NewLC(const TDesC8 &aBinaryData);

Description

Creates a new CX520AttributeTypeAndValue object from the specified buffer containing the encoded binary representation, and puts a pointer to the new object onto the cleanup stack.

Initialises the object from its encoded binary form into an internal representation.

Parameters

Return value

IMPORT_C static CX520AttributeTypeAndValue* NewL(const TDesC8 &aBinaryData, TInt &aPos);

Description

Creates a new CX520AttributeTypeAndValue object from the specified buffer containing the encoded binary representation, starting at the specified offset.

Initialises the object from its encoded binary form into an internal representation.

Parameters

Return value

IMPORT_C static CX520AttributeTypeAndValue* NewLC(const TDesC8 &aBinaryData, TInt &aPos);

Description

Creates a new CX520AttributeTypeAndValue object from the specified buffer containing the encoded binary representation, starting at the specified offset, and puts a pointer to the new object onto the cleanup stack.

Initialises the object from its encoded binary form into an internal representation.

Parameters

Return value

IMPORT_C static CX520AttributeTypeAndValue* NewL(const CX520AttributeTypeAndValue &aPair);

Description

Creates a new CX520AttributeTypeAndValue object from an existing object.

This is equivalent to a copy constructor.

Parameters

Return value

IMPORT_C static CX520AttributeTypeAndValue* NewLC(const CX520AttributeTypeAndValue &aPair);

Description

Creates a new CX520AttributeTypeAndValue object from an existing object, and puts a pointer to the new object onto the cleanup stack.

This is equivalent to a copy constructor.

Parameters

Return value

Parameters

Return value

IMPORT_C static CX520AttributeTypeAndValue* NewLC(RReadStream &aStream);

Description

Creates a new CX520AttributeTypeAndValue object from the specified read stream, and puts a pointer to the new object onto the cleanup stack.

Parameters

Return value

IMPORT_C static CX520AttributeTypeAndValue* NewL(TAttributeType aType, const TDesC8 &aValue);

Description

Creates a new CX520AttributeTypeAndValue object from an attribute type and value.

Parameters

Return value

IMPORT_C static CX520AttributeTypeAndValue* NewLC(TAttributeType aType, const TDesC8 &aValue);

IMPORT_C const TPtrC Type() const;

Description

Gets the encoded attribute type of the object.

Return value

IMPORT_C const TPtrC8 EncodedValue() const;

Description

Gets the encoded attribute value of the object.

Return value

IMPORT_C virtual HBufC* ValueL() const;

Description

Gets the decoded value.

Return value

IMPORT_C CASN1EncSequence* EncodeASN1LC() const;

Description

Encodes the contents into an ASN.1 sequence object.

This is useful to insert attribute type/value pairs into other ASN.1 encoding trees.

Return value

IMPORT_C CASN1EncSequence* EncodeASN1L() const;

Description

Encodes the contents into an ASN.1 sequence object.

Useful to insert attribute type/value pairs into other ASN.1 encoding trees.

Return value

IMPORT_C virtual TBool ExactMatchL(const CX520AttributeTypeAndValue &aElement) const;

Description

Compares the attribute type and decoded value of the specified object.

Parameters

Return value

virtual void ExternalizeL(RWriteStream &aStream) const;

Description

Externalises an object of this class to a write stream.

The presence of this function means that the standard templated operator<<(RWriteStream &,const T &) can be used to externalise objects of this class.

Parameters
