SYNOPSIS

Read & write loci:

use strict;
use Bio::Polloc::LocusIO;

my $locusI = Bio::Polloc::LocusIO->new(-file=>"t/loci.gff3", -format=>"gff3");
my $locusO = Bio::Polloc::LocusIO->new(-file=>">out.gff3", -format=>"gff3");

while(my $locus = $locusI->next_locus){
   print "Got a ", $locus->type, " from ", $locus->from, " to ", $locus->to, "\n";
   # Filter per type
   if($locus->type eq "repeat"){
      $locusO->write_locus($locus);
   }
}

PUBLIC METHODS

Methods provided by the package

new

The basic initialization method

format

Gets/sets the format of the file

Arguments

Format (str), currently supported: gff3.

Return

Format (str or undef).

write_locus

Appends one locus to the output file.

Arguments

-locus Bio::Polloc::LocusI, mandatory

The locus to append.

-force Bool (int)

If true, forces re-parsing of the locus. Otherwise, tries to load cached parsing (if any).

read_loci

Gets the loci stored in the input file.

Arguments

-genomes arrayref of Bio::Polloc::Genome objects

An arrayref containing the Bio::Polloc::Genome objects associated to the collection of loci. This is not mandatory, but seq and genome properties will not be set on the newly created objects if this parameter is not provided.

Returns

A Bio::Polloc::LociGroup object.

next_locus

Reads the next locus in the buffer.

Arguments

Same of read_loci()

Returns

A Bio::Polloc::LocusI object.

INTERNAL METHODS

Methods intended to be used only within the scope of Bio::Polloc::*

_qualify_format

Uniformizes the distinct names that every format can receive

Arguments

The requested format (str)

Returns

The qualified format (str or undef)

_write_locus_impl

Format-specific implementation of write_locus().

_read_loci_impl

Format-specific implementation of next_locus.

_next_locus_impl

_save_locus

_locus_by_id

_initialize
