NAME

Bio::Search::Result::ResultI - Abstract interface to Search Result objects

SYNOPSIS

# 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;

DESCRIPTION

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.

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

next_hit

 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

query_name

 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

query_accession

 Title   : query_accession
 Usage   : $id = $result->query_accession();
 Function: Get the accession (if available) for the query sequence
 Returns : a string
 Args    : none

query_length

 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

query_description

 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

database_name

 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

database_letters

 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

database_entries

 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

get_parameter

 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)

available_parameters

 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

get_statistic

 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)

available_statistics

 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

algorithm

 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

algorithm_version

 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
