Bio::Tools::EUtilities::Summary::DocSum(3pm)

Usage

  # Implement ItemContainerI
  # $foo is any ItemContainerI (current implementations are DocSum and Item itself)
  while (my $item = $foo->next_Item) { # iterate through contained Items
     # do stuff here
  }
  @items = $foo->get_Items;  # all Items in the container (hierarchy intact)
  @items = $foo->get_all_Items;  # all Items in the container (flattened)
  @items = $foo->get_Items_by_name('bar'); # Specifically named Items
  ($content) = $foo->get_contents_by_name('bar'); # content from specific Items
  ($type) = $foo->get_type_by_name('bar'); # data type from specific Items

get_ids

 Title    : get_ids
 Usage    : my ($id) = $item->get_ids;
 Function : returns array or array ref with id
 Returns  : array or array ref
 Args     : none
