Class Description
An InformixContext represents a single transaction scope on the database server to which its adaptor object is connected. If the server supports multiple concurrent transaction sessions, the adaptor may have several adaptor contexts. An InformixContext may in turn have several InformixChannels, which handle actual access to the data on the server.
The features the InformixContext class adds to EOAdaptorContext are methods for setting Informix-specific characteristics for the context.
