Bio::DB::Biblio::soap - A SOAP-based access to a bibliographic query service
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 = Bio::Biblio->new (-access => 'soap');
This object contains the real implementation of a Bibliographic Query Service as defined in Bio::DB::BiblioI - using a SOAP protocol to access a WebService (a remote server) that represents a bibliographic repository.
User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the Bioperl mailing list. Your participation is much appreciated.

This module is free software; you can redistribute it and/or modify it under the same terms as Perl itself.
This software is provided "as is" without warranty of any kind.
Methods returning a boolean value (has_next, exists and contains) can be used only with SOAP::Lite version 0.52 and newer (probably due to a bug in the older SOAP::Lite).
It does not use WSDL.
More testing and debugging needed to ensure that returned citations are properly transferred even if they contain foreign characters.
The main documentation details are to be found in Bio::DB::BiblioI.
Here is the rest of the object methods. Internal methods are preceded with an underscore _.
Usage : my $obj = new Bio::Biblio (-access => 'soap' ...); (_initialize is internally called from this constructor) Returns : nothing interesting Args : This module recognises and uses following arguments: -namespace => 'urn' The namespace used by the WebService that is being accessed. It is a string which guarantees its world-wide uniqueness - therefore it often has a style of a URL - but it does not mean that such pseudo-URL really exists. Default is 'http://industry.ebi.ac.uk/openBQS'. -destroy_on_exit => '0' Default value is '1' which means that all Bio::Biblio objects - when being finalised - will send a request to the remote WebService to forget the query collections they represent. If you change it to '0' make sure that you know the query collection identification - otherwise you will not be able to re-established connection with it. This can be done by calling method get_collection_id. -collection_id => '...' It defines what query collection will this object work with. Use this argument when you know a collection ID of an existing query collection and when you wish to re-established connection with it. By default, the collection IDs are set automatically by the query methods - they return Bio::Biblio objects already having a collection ID. A missing or undefined collection ID means that the object represents the whole bibliographic repository (which again means that some methods, like get_all, will be probably refused). -soap => a SOAP::Lite object Usually all Bio::Biblio objects share an instance of the underlying SOAP::Lite module. But you are free to have more - perhaps with different characteristics. See the code for attributes of the default SOAP::Lite object. -httpproxy => 'http://server:port' In addition to the 'location' parameter, you may need to specify also a location/URL of a HTTP proxy server (if your site requires one). Additionally, the main module Bio::Biblio recognises also: -access => '...' -location => '...'
It populates calling object with the given arguments, and then - for some attributes and only if they are not yet populated - it assigns some default values.
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.
Usage : print $Bio::DB::Biblio::soap::VERSION; print $Bio::DB::Biblio::soap::Revision;
Usage : print $Bio::DB::Biblio::soap::DEFAULT_SERVICE; print $Bio::DB::Biblio::soap::DEFAULT_NAMESPACE;
