Bio::Search::Result::ResultI - Abstract interface to Search Result objects
# Bio::Search::Result::ResultI objects cannot be instantiated since this # module defines a pure interface.
# Given an object that implements the Bio::Search::Result::ResultI interface, # you can do the following things with it:
use Bio::SearchIO; my $io = new Bio::SearchIO(-format => 'blast', -file => 't/data/HUMBETGLOA.tblastx'); my $result = $io->next_result; while( $hit = $result->next_hit()) { # enter code here for hit processing } my $id = $result->query_name(); my $desc = $result->query_description(); my $dbname = $result->database_name(); my $size = $result->database_letters(); my $num_entries = $result->database_entries(); my $gap_ext = $result->get_parameter('gapext'); my @params = $result->available_parameters; my $kappa = $result->get_statistic('kappa'); my @statnames = $result->available_statistics;
Bio::Search::Result::ResultI objects are data structures containing the results from the execution of a search algorithm. As such, it may contain various algorithm specific information as well as details of the execution, but will contain a few fundamental elements, including the ability to return Bio::Search::Hit::HitI objects.

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
Title : next_hit Usage : while( $hit = $result->next_hit()) { ... } Function: Returns the next available Hit object, representing potential matches between the query and various entities from the database. Returns : a Bio::Search::Hit::HitI object or undef if there are no more. Args : none
Title : query_name Usage : $id = $result->query_name(); Function: Get the string identifier of the query used by the algorithm that performed the search. Returns : a string. Args : none
Title : query_accession Usage : $id = $result->query_accession(); Function: Get the accession (if available) for the query sequence Returns : a string Args : none
Title : query_length Usage : $id = $result->query_length(); Function: Get the length of the query sequence used in the search. Returns : a number Args : none
Title : query_description Usage : $id = $result->query_description(); Function: Get the description of the query sequence used in the search. Returns : a string Args : none
Title : database_name Usage : $name = $result->database_name() Function: Used to obtain the name of the database that the query was searched against by the algorithm. Returns : a scalar string Args : none
Title : database_letters Usage : $size = $result->database_letters() Function: Used to obtain the size of database that was searched against. Returns : a scalar integer (units specific to algorithm, but probably the total number of residues in the database, if available) or undef if the information was not available to the Processor object. Args : none
Title : database_entries Usage : $num_entries = $result->database_entries() Function: Used to obtain the number of entries contained in the database. Returns : a scalar integer representing the number of entities in the database or undef if the information was not available. Args : none
Title : get_parameter Usage : my $gap_ext = $result->get_parameter('gapext') Function: Returns the value for a specific parameter used when running this result Returns : string Args : name of parameter (string)
Title : available_parameters Usage : my @params = $result->available_parameters Function: Returns the names of the available parameters Returns : Return list of available parameters used for this result Args : none
Title : get_statistic Usage : my $gap_ext = $result->get_statistic('kappa') Function: Returns the value for a specific statistic available from this result Returns : string Args : name of statistic (string)
Title : available_statistics Usage : my @statnames = $result->available_statistics Function: Returns the names of the available statistics Returns : Return list of available statistics used for this result Args : none
Title : algorithm Usage : my $r_type = $hsp->algorithm Function: Obtain the name of the algorithm used to obtain the Result Returns : string (e.g., BLASTP) Args : [optional] scalar string to set value
Title : algorithm_version Usage : my $r_version = $hsp->algorithm_version Function: Obtain the version of the algorithm used to obtain the Result Returns : string (e.g., 2.1.2) Args : [optional] scalar string to set algorithm version value
