Bio::AnalysisParserI - Generic analysis output parser interface # get a AnalysisParserI somehow. # Eventually, there may be an Bio::Factory::AnalysisParserFactory. # For now a SearchIO object, an implementation of AnalysisParserI, can be created # directly, as in the following: my $parser = Bio::SearchIO->new( '-file' => 'inputfile', '-format' => 'blast'); while( my $result = $parser->next_result() ) { print "Result: ", $result->analysis_method, ", Query: ", $result->query_name, "\n"; while( my $feature = $result->next_feature() ) { print "Feature from ", $feature->start, " to ", $feature->end, "\n"; } } AnalysisParserI is a interface for describing generic analysis result parsers. This module makes no assumption about the nature of analysis being parsed, only that zero or more result sets can be obtained from the input source. This module was derived from Bio::SeqAnalysisParserI, the differences being Instead of flattening a stream containing potentially multiple analysis results into a single set of features, AnalysisParserI segments the stream in terms of analysis result sets (Bio::AnalysisResultI objects). Each AnalysisResultI can then be queried for its features (if any) as well as other information about the result It does not inherit from Bio::Root::RootI and does not provide a new() method. Implementations are free to choose how to implement it.

Rationale (copied from Bio::SeqAnalysisParserI)
The concept behind this interface is to have a generic interface in sequence annotation pipelines (as used e.g. in high-throughput automated sequence annotation). This interface enables plug-and-play for new analysis methods and their corresponding parsers without the necessity for modifying the core of the annotation pipeline. In this concept the annotation pipeline has to rely on only a list of methods for which to process the results, and a factory from which it can obtain the corresponding parser implementing this interface.

TODO
Create Bio::Factory::AnalysisParserFactoryI and Bio::Factory::AnalysisParserFactory for interface and an implementation. Note that this factory could return Bio::SearchIO-derived objects.
