    40 Abstract base class for WAP Push Content Handler plug-ins.

    41 

    42 A WAP Push Content Handler plug-in processes a WAP Push message that contains 

    43 data of a specific media type. A Content Handler plug-in is loaded by a WAP Push Application

    44 Handler plug-in (CPushHandlerBase-derived object), and the message is passed to handle 

    45 through HandleMessageL().

    46 

    47 A WAP Push Content Handling plugin is implemented as an ECom plug-in object derived from 

    48 the CContentHandlerBase interface.

    49 

    50 Each Content Handler plug-in should specify the media type that it handles. Content Handler 

    51 plug-ins can handle multiple media types: for example, a plug-in to handle SI messages can

    52 specify it's media type as "text/vnd.wap.si||application/vnd.wap.sic".
