Class Description
An InformixChannel represents an independent communication channel to the database server its InformixAdaptor is connected to. All of an InformixChannel's operations take place within the context of transactions controlled or tracked by its InformixContext. An InformixContext can manage multiple InformixChannels, and a channel is associated with only one context.
The features InformixChannel adds to EOAdaptorChannel are as follows:
cursorDataArea
If the channel is connected, returns an Informix-specific data structure describing characteristics of the channel. Otherwise, returns NULL.
fetchBufferLength
- (unsigned)fetchBufferLength
Returns the size, in bytes, of the fetch buffer. The larger the buffer, the more rows can be returned for each round trip to the server.

(InformixIsolationLevel)isol
Sets to isolationLevel the isolation transaction level of the connection represented by the receiver.
setFetchBufferLength:
- (void)setFetchBufferLength:
(unsigned)length
Sets to length the size, in bytes, of the fetch buffer. The larger the buffer, the more rows can be returned for each round trip to the server.
