NAME

Bio::DB::Biblio::pdf - Fetch PDF for a PubMed ID

SYNOPSIS

Do not use this object directly, it is recommended to access it and use it through the Bio::Biblio module:

use Bio::Biblio;
my $biblio = new Bio::Biblio (-access => 'pdf');

DESCRIPTION

This object contains the real implementation of a Bibliographic Query Service as defined in Bio::DB::BiblioI.

Bio::DB::BiblioI is not implemented as documented in the interface, particularly the find() method, which is not compatible with PubMed's query language.

BUGS AND LIMITATIONS

  • Of course, you'll need access to the sites hosting the PDFs to download them.

    = item *

    If you're having problems retrieving PDF from a site you have access to, you might try adjusting the max_depth() attribute. It is default set to 3, and affects how many links deep will be recursively followed in page fetches to try to find your PDF.

APPENDIX

The main documentation details are to be found in Bio::DB::BiblioI.

Here is the rest of the object methods. Interface methods first, followed by internal methods.

_initialize

Usage   : my $obj = new Bio::Biblio (-access => 'pdf' ...);
          (_initialize is internally called from this constructor)
Returns : 1 on success
Args    : none

This is an actual new() method (except for the real object creation and its blessing which is done in the parent class Bio::Root::Root in method _create_object).

Note that this method is called always as an object method (never as a class method) - and that the object who calls this method may already be partly initiated (from Bio::Biblio::new method); so if you need to do some tricks with the 'class invocation' you need to change Bio::Biblio::new method, not this one.

get_next

Title   : get_next
Usage   : $xml = $biblio->get_next();
Function: return next record as xml
Returns : an xml string

find
