Method: FileMonitoring::DirStat#load_symlink

Defined in:
lib/file_monitoring/monitor_path.rb

add symlink while initializing tree using content data from file.

Assumption is that Tree already built

Parameters:

sub_paths - Array of sub paths of the symlink which is added to tree
            Example:
              instance path = /dir1/dir2/file_name
                Sub path 1: /dir1
                Sub path 2: /dir1/dir2
                Sub path 3: /dir1/dir2/file_name
            sub paths would create DirStat objs or FileStat(FileStat create using last sub path).
sub_paths_index - the index indicates the next sub path to insert to the tree
                  the index will be raised at each recursive call down the tree
symlink_path - symlink file path
symlink_target - the target path pointed by the symlink
