GetBetterMplexID()

int ChannelUtil::GetBetterMplexID ( int  current_mplexid, int  transport_id, int  network_id  )

static

Returns best match multiplex ID, creating one if needed.

First, see if you can get an exact match based on the current mplexid's sourceID and the NetworkID/TransportID.

Next, see if current one is NULL, if so update those values and return current mplexid.

Next, if values were set, see where you can find this NetworkID/TransportID. If we get an exact match just return it, since there is no question what mplexid this NetworkId/TransportId is for. If we get many matches, return CurrentMplexID.

Next, try to repeat query without currentmplexid as source id. If we get a singe match return it, if we get many matches we return the first one.

If none of these work return -1.

Returns

mplexid on success, -1 on failure.

static

Load channels from database into a list of ChannelInfo objects.

Note

This replaces all previous methods e.g. GetChannels() and GetAllChannels() in channelutil.h

There is no grouping option by design and here's why. Grouping with a ChannelInfo object is largely self-defeating, 99% of the information in the remaining result won't apply to the other 'grouped' channels. Therefore GroupBy should be used when you only care about Name, Number and Callsign. Loading a complete ChannelInfo object, including input info is therefore an actual waste of processor cycles and memory, so we may yet introduce a parent class for ChannelInfo called BasicChannelInfo or similar with it's own Load function
