NAME

SYNOPSIS

#include "tifInternal.h"
tifMAIN_TASK app; USE(app);

PARENT CLASS

evhSTD_COMMANDS

DESCRIPTION

This class implements the tif main application.

PUBLIC METHODS

tifMAIN_TASK();
    The constructor loads the routing table and installs all the callbacks
    for commands to be routed to TCS modules. The standard commands which
    are treated by the tif module itself are processed by the parent class
    evhSTD_COMMANDS.

~tifMAIN_TASK();
The destructor unregisters all the callbacks and frees the in-memory
routing table.

evhCB_COMPL_STAT InitCB(msgMESSAGE &msg, void *userData);
    Handles the INIT command, reloades the routing table.

evhCB_COMPL_STAT ExitCB(msgMESSAGE &msg, void *userData);
    Handles the EXIT command.

evhCB_COMPL_STAT RouteCommand(msgMESSAGE &msg, tifROUTING *route);
    The command router creates a tifCOMMAND object from the received
    user command, sends it to the appropriate TCS process and installs
    callbacks to handle the replies/error reply/timeout.

evhCB_COMPL_STAT GenericCB(msgMESSAGE &msg, void *userData);
    This method is installed to handle all unknown user commands by
    discarding them and returning an error reply.

evhCB_COMPL_STAT PrintTable(msgMESSAGE &msg, void *userData);
    PRNCMD command handler. Prints the loaded routing table onto the
    standard output.
