NAME
Bio::SearchIO::blasttable - Driver module for SearchIO for parsing NCBI -m 8/9 format
SYNOPSIS
# do not use this module directly
use Bio::SearchIO;
my $parser = Bio::SearchIO->new(-file => $file,
-format => 'blasttable');
while( my $result = $parser->next_result ) {
}
DESCRIPTION
This module will support parsing NCBI -m 8 or -m 9 tabular output and WU-BLAST -mformat 2 or -mformat 3 tabular output.

Support
Please direct usage questions or support issues to the mailing list:
bioperl-l@bioperl.org
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.

APPENDIX
The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
new
Title : new
Usage : my $obj = Bio::SearchIO::blasttable->new();
Function: Builds a new Bio::SearchIO::blasttable object
Returns : an instance of Bio::SearchIO::blasttable
Args :
next_result
Title : next_result
Usage : my $result = $parser->next_result
Function: Parse the next result from the data stream
Returns : L<Bio::Search::Result::ResultI>
Args : none
start_element
Title : start_element
Usage : $eventgenerator->start_element
Function: Handles a start element event
Returns : none
Args : hashref with at least 2 keys 'Data' and 'Name'
end_element
Title : start_element
Usage : $eventgenerator->end_element
Function: Handles an end element event
Returns : none
Args : hashref with at least 2 keys 'Data' and 'Name'
element
Title : element
Usage : $eventhandler->element({'Name' => $name, 'Data' => $str});
Function: Convience method that calls start_element, characters, end_element
Returns : none
Args : Hash ref with the keys 'Name' and 'Data'
characters
Title : characters
Usage : $eventgenerator->characters($str)
Function: Send a character events
Returns : none
Args : string
_mode
Title : _mode
Usage : $obj->_mode($newval)
Function:
Example :
Returns : value of _mode
Args : newvalue (optional)
within_element
Title : within_element
Usage : if( $eventgenerator->within_element($element) ) {}
Function: Test if we are within a particular element
This is different than 'in' because within can be tested
for a whole block.
Returns : boolean
Args : string element name
in_element
Title : in_element
Usage : if( $eventgenerator->in_element($element) ) {}
Function: Test if we are in a particular element
This is different than 'in' because within can be tested
for a whole block.
Returns : boolean
Args : string element name
start_document
Title : start_document
Usage : $eventgenerator->start_document
Function: Handles a start document event
Returns : none
Args : none
end_document
Title : end_document
Usage : $eventgenerator->end_document
Function: Handles an end document event
Returns : Bio::Search::Result::ResultI object
Args : none
result_count
Title : result_count
Usage : my $count = $searchio->result_count
Function: Returns the number of results we have processed
Returns : integer
Args : none
program_name
Title : program_name
Usage : $obj->program_name($newval)
Function: Get/Set the program name
Returns : value of program_name (a scalar)
Args : on set, new value (a scalar or undef, optional)
_will_handle
Title : _will_handle
Usage : Private method. For internal use only.
if( $self->_will_handle($type) ) { ... }
Function: Provides an optimized way to check whether or not an element of a
given type is to be handled.
Returns : Reference to EventHandler object if the element type is to be handled.
undef if the element type is not to be handled.
Args : string containing type of element.
Optimizations:
1.
Using the cached pointer to the EventHandler to minimize repeated lookups.
2.
Caching the will_handle status for each type that is encountered so that it only need be checked by calling handler->will_handle($type)
once.
This does not lead to a major savings by itself (only 5-10%). In combination with other optimizations, or for large parse jobs, the
savings good be significant.
To test against the unoptimized version, remove the parentheses from around the third term in the ternary " ? : " operator and add two
calls to $self->_eventHandler().
