The SIP Codec API provides functions to encode and decode SIP headers and -their fields. It converts SIP messages from the UTF-8 ASCII format to the -API implementations internal structure and from the API implementations internal -structure to the UTF-8 ASCII format. This implementation validates the SIP -message syntax according to the SIP BNF definition and supports serialization -and de-serialization of objects belonging to the SIP message structure.

This implementation is provided in a shared DLL and is run in the context -of the user. It creates class instances in the user heap area which means -the instances cannot be shared between different users.

Architectural -relationships

The SIP Codec API does not require any interfaces.

Capability -information

There is no capability required when you use the SIP -Codec API. This API is valid for all platforms running Symbian OS version -9.1.

Extending the API

SIP Codec API cannot be extended.

-
Class structure

The -logical type of the SIP Codec API is Library API. This interface contains -synchronous functions that do not block, but return immediately and it uses -only local objects.

The following illustration shows the relationships -of the SIP Codec API classes.

The SIP Codec API defines the functions required to create the SIP -headers of a SIP message. CSIPHeaderBase is the base class for all SIP headers. -A client creates a new instance of the CSIPXHeader class, where “X” is the -name of the header required, and sets the values of the header with the setter -functions of this class.

Memory used

The -amount of memory used by every header object of the SIP Codec API is equivalent -to the memory used by the header as text (class + the size of SIP headers).
