13 // Description: |
|
14 // The factory class which is used to instantiate the MbufGobbler flow. |
|
15 // (data plane) |
|
16 // |
|
17 // |
|
18 // This is a 3-plane comms layer implementation example, which has been customised to be a test layer which gobbles and releases ESOCK MBUFs. |
|
19 // The MBuf gobbling functionality can be disabled by undefining the macro SYMBIAN_COMMSFW_MBUF_GOBBLER which is specified in mbufgobblerproviders.mmp. |
|
20 // When SYMBIAN_COMMSFW_MBUF_GOBBLER is undefined, the source code specified by mbufgobblerproviders.mmp becomes a pass through layer i.e. it passes the data |
|
21 // through to the layer above or below without altering it. This makes it useful as a starting point for implementing your own layers / providers; |
|
22 // useful documentation on how to customise your own passthrough layer can be found in ..\docs\MbufGobblerLayer.doc |
|
