It looks like trailsByChannel is a hash where the key is a string like 
"foo|bar" where foo is the $channelX and bar is the $pathtype. The data 
value in the hash is a hash reference, where the key is $cctName and the 
data value is 1.

eg.
{
           'foo|bar' => {
                          'baz' => 1
                        }
         };
