 Object[] iParameters,
 OCommandContext iContext)

Description copied from interface: OSQLFunction

Process a record.

Parameters:

iThis -

iCurrentRecord - : current record

iCurrentResult - TODO

iParameters - : function parameters, number is ensured to be within minParams and maxParams.

iContext - : object calling this function

Returns:

function result, can be null. Special cases : can be null if function aggregate results, can be null if function filter results : this mean result is excluded
