CASN1EncBase ( const TTagType, const TASN1Class )

IMPORT_C	CASN1EncBase	(	const TTagType	aType,
			const TASN1Class	aClass
		)	[protected]

Protected constructor

Parameters
aType	Tag type of the new object

Member Function Documentation

CalculateLengthLengthDER ( )

void

CalculateLengthLengthDER

(

)

[protected]

Calculates number of octets in DER length encoding. Must set value of the appropriate data member. Made protected because it is needed by CASN1EncEncoding class.

ConstructL ( )

IMPORT_C void

ConstructL

(

)

[protected, virtual]

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

ContentsLengthChanged ( )

void

ContentsLengthChanged

(

)

[protected]

Derived classes must call this if the length of their contents changes after construction.

LengthDER ( )

IMPORT_C TUint

LengthDER

(

)

const

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

Return Value: Number of octets in DER encoding of this object.

SetParent ( CASN1EncBase * )

void

SetParent

(

CASN1EncBase *

aParent

)

Sets parent for the object

Parameters
aParent	Pointer to an ASN.1 object that becomes this object's parent.

SetTag ( const TTagType, const TASN1Class )

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

Sets tag type/class of the encoding object

Parameters
aType	Tag type to set
aClass	Tag class to set.

WriteDERL ( TDes8 &, TUint & )

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

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

Parameters
aBuf	Buffer receiving the encoding.
aPos	Position to start writing at.
