=head1 NAME
Bio::DB::SoapEUtilities::GQueryAdaptor - Handle for Entrez SOAP GlobalQuery items
=head1 SYNOPSIS
my $fac = Bio::DB::SoapEUtilities->new();
# run a query, returning a GQueryAdaptor
my $queries = $fac->egquery( -term => 'BRCA and human' )->run(-auto_adapt=>1);
# all databases with hits
my @dbs = $queries->found_in_dbs;
# queries by database
my $prot_count = $queries->query_by_db('prot')->count;
# iterate over gquery
while ( my $q = $queries->next_query ) {
my $db = $q->db;
my $count = $q->count;
my $status = $q->status;
}
=head1 DESCRIPTION
This adaptor provides an iterator (C<next_query()>) and other
convenience functions for parsing NCBI Entrez EUtility C<egquery>
SOAP results.

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.

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.
