TFBS::SiteSet(3) a set of TFBS::Site objects


my $site_set = TFBS::SiteSet->new(@list_of_site_objects);
# add a TFBS::Site object to set:

# append another TFBS::SiteSet contents:
# create an iterator:
my $it = $site_set->Iterator(-sort_by => 'start');


TFBS::SiteSet is an aggregate class that contains a collection of TFBS::Site objects. It can be created anew and filled with TFBS::Site object. It is also returned by search_seq() method call of some TFBS::PatternI subclasses (e.g. TFBS::Matrix::PWM).

The rest of the documentation details each of the object methods. Internal methods are preceded with an underscore.


 Title   : add_site
 Usage   : $siteset->add_site($site_object)
 Function: adds TFBS::Site objects to an existing TFBS::SiteSet object
 Returns : $sitepair object (usually ignored)
 Args    : A list of TFBS::Site objects to add


 Title   : add_site_set
 Usage   : $siteset->add_site_set($site_set_object)
 Function: adds the contents of other TFBS::SiteSet objects 
           to an existing TFBS::SiteSet object
 Returns : $siteset object (usually ignored)
 Args    : A list of TFBS::SiteSet objects whose contents should be 
           added to $siteset


 Title   : size
 Usage   : my $size = $siteset->size()
 Function: returns a number of TFBS::Site objects contained in the set
 Returns : a scalar (integer) 
 Args    : none


 Title   : Iterator
 Usage   : my $siteset_iterator = 
                   $siteset->Iterator(-sort_by =>'start');
           while (my $site = $siteset_iterator->next) {
               # do whatever you want with individual matrix objects
 Function: Returns an iterator object that can be used to go through
           all members of the set (TFBS::Site objects)
 Returns : an iterator object (currently undocumentened in TFBS -
                               but understands the 'next' method)
 Args    : -sort_by # optional - currently it accepts 
                    #   (default sort order in parenthetse)
                    #    'name' (pattern name, alphabetically)
                    #    'ID' (pattern/matrix ID, alphabetically)
                    #    'start' (site start in sequence, 
                    #             numerically,increasing order)
                    #    'end' (site end in sequence, 
                    #           numerically, increasing order)
                    #    'score' (numerically, decreasing order)
           -reverse # optional - reverses the default sorting order if true


 Title   : GFF
 Usage   : print $siteset->GFF();
         : print $siteset->GFF($gff_formatter)
 Function: returns a "standard" multiline GFF string 
 Returns : a string (multiline, newline terminated)
 Args    : a $gff_formatter function reference (optional)
