SYNOPSIS

$fac = Bio::DB::ESoap->new( -util => 'esearch' );
$som = $fac->run( -db => 'prot', -term => 'HIV and gp120' );
$fac->set_parameters( -term => 'HIV2 and gp160' );
# accessors corresponding to valid parameters are also created:
$fac->db('nuccore');
$som = $fac->run;
# more later.

DESCRIPTION

"ESoap" provides a basic SOAP interface to the NCBI Entrez Utilities Web Service (<http://eutils.ncbi.nlm.nih.gov/entrez/eutils/soap/v2.0/DOC/esoap_help.html>). SOAP::Lite handles the SOAP calls. Higher level access, pipelines, BioPerl object I/O and such are provided by Bio::DB::SoapEUtilities.

"ESoap" complies with Bio::ParameterBaseI. It depends explicitly on NCBI web service description language files to inform the "available_parameters()" method. WSDLs are parsed by a relative lightweight, Entrez-specific module Bio::DB::ESoap::WSDL.

The "run()" method returns SOAP::SOM (SOAP Message) objects. No fault checking or other parsing is performed in this module.

Support

Please direct usage questions or support issues to the mailing list:

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.

 Returns : an instance of Bio::DB::ESoap
 Args    :

_wsdl()

 Title   : _wsdl
 Usage   : $obj->_wsdl($newval)
 Function: Bio::DB::ESoap::WSDL object associated with 
           this factory
 Example : 
 Returns : value of _wsdl (object)
 Args    : on set, new value (object or undef, optional)

_client()

 Title   : _client
 Usage   : $obj->_client($newval)
 Function: holds a SOAP::Lite object
 Example : 
 Returns : value of _client (a SOAP::Lite object)
 Args    : on set, new value (a SOAP::Lite object or undef, optional)

_operation()

 Title   : _operation
 Alias   : util
 Usage   : 
 Function: check and convert the requested operation based on the wsdl
 Returns : 
 Args    : operation (scalar string)

action()

 Title   : action

run()

 Title   : _run
 Usage   : $som = $self->_run(@optional_setting_args)
 Function: Call the SOAP service with the factory-associated utility
           and parameters
 Returns : SOAP::SOM (SOAP Message) object
 Args    : named parameters appropriate for the utility
 Note    : no fault checking here

Bio::ParameterBaseI compliance

parameters_changed()

 Title   : parameters_changed
 Usage   : $obj->parameters_changed($newval)
 Function: flag to indicate, well, you know
 Example :
