Bio::Tools::EUtilities::Summary - class for handlign data output (XML) from esummary.


  #### should not create instance directly; Bio::Tools::EUtilities does this ####

  my $esum = Bio::Tools::EUtilities->new(-eutil => 'esummary',
                                         -file => 'summary.xml');
  # can also use '-response' (for HTTP::Response objects) or '-fh' (for filehandles)

  while (my $docsum = $esum->next_DocSum) {
      my $id = $docsum->get_ids;  # EUtilDataI compliant method, returns docsum ID
      my @names = $docsum->get_item_names;


This class handles data output (XML) from esummary.

esummary retrieves information in the form of document summaries (docsums) when passed a list of primary IDs or if using a previous search history.

This module breaks down the returned data from esummary into individual document summaries per ID (using a DocSum object). As the data in a docsum can be nested, subclasses of DocSums (Item, ListItem, Structure) are also present.

Further documentation for Link and Field subclass methods is included below.
