Bio::Tools::EUtilitiesUserfContributeBio::Tools::EUtilities::Info::LinkInfo(3)NAMEBio::Tools::EUtilities::Info::LinkInfo - class for storing einfo link
data
SYNOPSIS
## should not create instance directly; Bio::Tools::EUtilities does this ##
# get a LinkInfo object using Bio:Tools::EUtilities
print "Link name: ",$link->get_link_name,"\n";
print "Link name: ",$link->get_link_menu_name,"\n";
print "Link desc: ",$link->get_link_description,"\n";
print "DBFrom: ",$link->get_dbfrom,"\n"; # database linked from
print "DBTo: ",$link->get_dbto,"\n"; # database linked to
DESCRIPTION
This class handles data output (XML) from einfo and elink.
einfo is capable of returning two types of information: 1) a list of
all available databases (when called w/o parameters) and 2) information
about a specific database. The latter information includes the database
description, record count, and date/time stamp for the last update,
among other things. It also includes a list of fields (indices by which
record data is stored which can be used in queries) and links
(crossrefs between related records in other databases at NCBI). Data
from the latter two are stored in two small subclasses (Field and Link)
which can be iterated through or retrieved all at once, as demonstrated
above. NOTE: Methods described for the Link and Field subclasses are
unique to those classes (as they retrieve data unique to those data
types).
Further documentation for Link and Field subclass methods is included
below.

Support
Please direct usage questions or support issues to the mailing list:
bioperl-l@bioperl.org
rather than to the module maintainer directly. Many experienced and
reponsive experts will be able look at the problem and quickly address
it. Please include a thorough description of the problem with code and
data examples if at all possible.

APPENDIX
The rest of the documentation details each of the object methods.
Internal methods are usually preceded with a _
new
Title : new
Note : *** should not be called by end-users ***
Usage : my $ct = Bio::Tools::EUtilities::Info::LinkInfo;
Function : returns new LinkInfo instance
Returns : Bio::Tools::EUtilities::Info::LinkInfo instance
Args : none (all data added via _add_data, most methods are getters only)
get_database
Title : get_database
Usage : my $db = $info->get_database;
Function : returns single database name (eutil-compatible). This is the
queried database. For elinks (which have 'db' and 'dbfrom')
this is equivalent to db/dbto (use get_dbfrom() to for the latter)
Returns : string
Args : none
get_db (alias for get_database)
get_dbto (alias for get_database)
get_dbfrom
Title : get_dbfrom
Usage : my $origdb = $link->get_dbfrom;
Function : returns referring database
Returns : string
Args : none
Note : alias for get_db()
get_link_name
Title : get_link_name
Usage : $ln = $link->get_link_name;
Function : returns raw link name (eutil-compatible)
Returns : string
Args : none
get_link_description
Title : get_link_description
Usage : $desc = $link->get_link_description;
Function : returns the (more detailed) link description
Returns : string
Args : none
get_link_menu_name
Title : get_link_menu_name
Usage : my $mn = $link->get_link_menu_name;
Function : returns formal menu name
Returns : string
Args : none
get_priority
Title : get_priority
Usage : my $mn = $link->get_priority;
Function : returns priority ranking
Returns : integer
Args : none
Note : only set when using elink and cmd set to 'acheck'
get_html_tag
Title : get_html_tag
Usage : my $tag = $link->get_html_tag;
Function : returns HTML tag
Returns : string
Args : none
Note : only set when using elink and cmd set to 'acheck'
get_url
Title : get_url
Usage : my $url = $link->get_url;
Function : returns URL string; note that the string isn't usable directly but
has the ID replaced with the tag <@UID@>
Returns : string
Args : none
Note : only set when using elink and cmd set to 'acheck'
to_string
Title : to_string
Usage : $foo->to_string()
Function : converts current object to string
Returns : none
Args : (optional) simple data for text formatting
Note : Used generally for debugging and for various print methods
