Class CASN1EncBase

class CASN1EncBase : public CBase;

Description

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

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

Description

protected: IMPORT_C CASN1EncBase(const TTagType aType, const TASN1Class aClass);

Description

Protected constructor

Parameters

protected: virtual IMPORT_C void ConstructL();

Description

Must call this version from derived classes in their ConstructL, but only once they're ready to have CalculateContentsLengthDER called on them.

IMPORT_C TUint LengthDER() const;

Description

Gives total number of octets in the DER encoding of this object.

Return value

IMPORT_C void WriteDERL(TDes8 &aBuf, TUint &aPos) const;

Description

Writes entire DER encoding of this object into the given buffer.

Parameters

IMPORT_C void SetTag(const TTagType aType, const TASN1Class aClass=EContextSpecific);

Description

Sets tag type/class of the encoding object

Parameters

protected: TUint iTagLengthDER;

Description

Length of DER encoded tag.

protected: TUint iLengthLengthDER;

Description

Length of DER encoded length.

protected: TUint iContentsLengthDER;

Description

Length of DER encoded content.
