    25 ECOM interface definition.

    26 

    27 

    28 This interface is derived from CHeaderCodec and it performs construction of Codec plugins 

    29 and allows the caller to determine which codecs are used and in which order. 

    30 

    31 

    32 The caller specifies the order of the desired codecs using a slash-separated string of names, 

    33 starting with the protocol name.

    34 

    35 

    36 for example:

    37 

    38 

    39 @code

    40 _LIT8(KHttpClientCodecName, "HTTP/client");

    41 CHeaderCodec* codec = CHeaderCodecPlugin::NewL( KHttpClientCodecName, iSession.StringPool());

    42 @endcode

    43 

    44 

    45 This says to use, for the HTTP protocol a client Codec, in addition to these are the implicit

    46 general and default HTTP Codecs.
