Class CASN1EncConstructed

class CASN1EncConstructed : public CASN1EncBase;

Description

Base class for all ASN1 constructed-type objects. Most of these are container classes, but another type is the explicit-tagging wrapper object.

Derivation

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

• CASN1EncBase - Base class for all ASN.1 types that we can encode.

• CASN1EncConstructed - Base class for all ASN1 constructed-type objects. Most of these are container cl...

Description

Parameters

const TUint aIndex

Return value

const CASN1EncBase &

private: virtual TUint NumChildren() const=0;

Description

Return value

TUint

private: virtual void CalculateContentsLengthDER();

Description

Calculates number of octets in DER content encoding. Must set value of the appropriate data member.

private: virtual TBool IsConstructed() const;

Description

Return value

TBool

private: virtual void WriteContentsDERL(TDes8 &aBuf) const;

Description

Writes DER content encoding into supplied buffer, which is already verified to be big enough. Must be implemented by derived classes.

Parameters

TDes8 &aBuf Buffer to write to.
