NAME

Data::Range::Compare::Stream::Iterator::Consolidate::FillMissing - Post Consolidation Iterator used to fill gaps

SYNOPSIS

use Data::Range::Compare::Stream::Iterator::Consolidate;
use Data::Range::Compare::Stream::Iterator::Array;
use Data::Range::Compare::Stream;
use Data::Range::Compare::Stream::Iterator::Consolidate::FillMissing;

my $array=Data::Range::Compare::Stream::Iterator::Array->new;

$array->create_range(0,0);
$array->create_range(1,1);
$array->create_range(3,4);
$array->create_range(6,7);

$array->set_sorted(1);

my $con=Data::Range::Compare::Stream::Iterator::Consolidate->new($array);
my $fill=new Data::Range::Compare::Stream::Iterator::Consolidate::FillMissing($con);

while($fill->has_next) {
  my $result=$fill->get_next;
  my $missing=$result->is_missing ? ' Gap' : '';
  print $result,$missing,"\n";
}

Resulting Output:

Commoon Range: [0 - 0] Starting range: [0 - 0] Ending Range: [0 - 0]
Commoon Range: [1 - 1] Starting range: [1 - 1] Ending Range: [1 - 1]
Commoon Range: [2 - 2] Starting range: [2 - 2] Ending Range: [2 - 2] Gap
Commoon Range: [3 - 4] Starting range: [3 - 4] Ending Range: [3 - 4]
Commoon Range: [5 - 5] Starting range: [5 - 5] Ending Range: [5 - 5] Gap
Commoon Range: [6 - 7] Starting range: [6 - 7] Ending Range: [6 - 7]

DESCRIPTION

This class Extends Data::Range::Compare::Stream::Iterator::Base. Unlike all other Consolidator object classes this class takes any consolidator as an argument and returns results that include both the data that was in the orginal set the gaps. Results that represent gaps are tag as $result->is_missing.

OO Methods

  • my $iterator=new Data::Range::Compare::Stream::Iterator::Consolidate::FillMissing($consolidator);

    Instance Constructor: $consolidator needs to be an object that implements or extends Data::Range::Compare::Stream::Iterator::Consolidate.

  • my $class=$iterator->NEW_RESULT_FROM;

    $class will contain the name of the class new result objects will be constructed from. Default value is Data::Range::Compare::Stream::Iterator::Consolidate::Result.

  • while($iterator->has_next) { ... }

    Returns true when there are more rows to fetch.

  • my $result=$iterator->get_next;

    Returns the next Result object. $result->is_missing will be true if the range was not in that set of data.
