CHeaderWriter Class Reference

class CHeaderWriter : public CBase

An abstract HTTP header encoder. CHeaderWriter provides an interface used by its owning codec to do conversion of header data from the generic internal header representation to the raw representation used for a particular protocol/transport. Specific sub-classes of CHeaderWriter are associated with specific protocol handlers.

CHeaderWriter()

IMPORT_C

CHeaderWriter

(

)

[protected]

Default constructor.

~CHeaderWriter()

IMPORT_C

~CHeaderWriter

(

[virtual]

Intended Usage: Destructor - cleans up and release resources to the system.

Member Functions Documentation

ConstructL()

IMPORT_C void

ConstructL

(

)

[protected]

Second phase construction in which any necessary allocation is done Implementations of this interface may leave with standard errors like KErrNoMemory.

EncodeHeaderL(RHeaderField &)

void

EncodeHeaderL

(

RHeaderField &

aHeader

)

[pure virtual]

Intended Usage: Encodes the supplied header field. This method does a conversion of the field into raw form from the generic internal representation.

Implementations of this interface may leave with any of KErrNotSupported, KErrHttpEncodeDoWWWAuthenticate, KErrHttpEncodeAuthorization, KErrHttpEncodeDoAge, KErrHttpEncodeDoVary, KErrHttpEncodeDoContentLanguage.

Specific header writer sub-classes must implement this method.

Parameters

RHeaderField & aHeader

(in) A proxy for the header field to be encoded
