This object implements the SearchWriterI interface which will produce
a set of HTML for a specific Bio::Search::Report::ReportI interface.
See Bio::SearchIO::SearchWriterI for more info on the filter method.

Title : new Usage : my $obj = new Bio::SearchIO::Writer::HTMLResultWriter(); Function: Builds a new Bio::SearchIO::Writer::HTMLResultWriter object Returns : Bio::SearchIO::Writer::HTMLResultWriter Args : -filters => hashref with any or all of the keys (HSP HIT RESULT) which have values pointing to a subroutine reference which will expect to get a -nucleotide_url => URL sprintf string base for the nt sequences -protein_url => URL sprintf string base for the aa sequences -no_wublastlinks => boolean. Do not display WU-BLAST lines even if they are parsed out. Links = (1)

Title : remote_database_url Usage : $obj->remote_database_url($type,$newval) Function: This should return or set a string that contains a %s which can be filled in with sprintf. Returns : value of remote_database_url Args : $type - 'PROTEIN' or 'P' for protein URLS 'NUCLEOTIDE' or 'N' for nucleotide URLS $value - new value to set [optional]

Purpose : Produces data for each Search::Result::ResultI in a string. : This is an abstract method. For some useful implementations, : see ResultTableWriter.pm, HitTableWriter.pm, : and HSPTableWriter.pm. Usage : print $writer->to_string( $result_obj, @args ); Argument : $result_obj = A Bio::Search::Result::ResultI object : @args = any additional arguments used by your implementation. Returns : String containing data for each search Result or any of its : sub-objects (Hits and HSPs). Throws : n/a

Title : hit_link_desc Usage : $self->hit_link_desc(\&link_function); Function: Get/Set the function which provides an HTML link(s) for the given hit to be used within the description section at the top of the BLAST report. This allows a person reading the report within a web browser to go to one or more database entries for the given hit from the description section. Returns : Function reference Args : Function reference See Also: default_hit_link_desc()

Title : defaulthit_link_desc Usage : $self->default_hit_link_desc($hit, $result) Function: Provides an HTML link(s) for the given hit to be used within the description section at the top of the BLAST report. This allows a person reading the report within a web browser to go to one or more database entries for the given hit from the description section. Returns : string containing HTML markup "See Also: hit_link_align, remote_database, id_parser

Title : hit_link_align Usage : $self->hit_link_align(\&link_function); Function: Get/Set the function which provides an HTML link(s) for the given hit to be used within the HSP alignment section of the BLAST report. This allows a person reading the report within a web browser to go to one or more database entries for the given hit from the alignment section. Returns : string containing HTML markup "See Also: hit_link_desc, remote_database, id_parser

Title : start_report Usage : $index->start_report( CODE ) Function: Stores or returns the code to write the start of the block, the block and the start of the <BODY> block of HTML. Useful for (for instance) specifying alternative HTML if you are embedding the output in an HTML page which you have already started. (For example a routine returning a null string). Returns \&default_start_report (see below) if not set. Example : $index->start_report( \&my_start_report ) Returns : ref to CODE if called without arguments Args : CODE</pre></td></tr></table> <div id="sep"></div> <table id="methDescTitle" width="100%"><tr><td WIDTH="200"><a name="_pod_default_start_report" id="_pod_default_start_report"></a><a name="POD8" id="POD8"></a>default_start_report</td><td ><a href="#CODE8">code</a></td><td ><a href="#POD7">prev</a></td><td ><a href="#POD9">next</a></td><td align="right"><a href="#TOP">Top</a></td></tr></table> <table id="methDescArea" width="100%"><tr><td><pre id="podParagraph"> Title : default_start_report Usage : $self->default_start_report($result) Function: The default method to call when starting a report.
