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. Any gaps in the input data set are filled in and marked as 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.

    Optional Arguments:

    factory_instance =>$obj
  
  # defines the object that implements the $obj->factory($start,$end,$data).
  # new ranges are constructed from the factory interfcae.  If a factory interface
  # is not created an instance of Data::Range::Compare::Stream is assumed.

  • 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.
