NAME

Data::Range::Compare::Stream::Iterator::Compare::Base - Abstract class

DESCRIPTION

This module provides the base shared hooks for the Compare Asc class and any future compare classes.

OO Methods

• my $compare=new Data::Range::Compare::Stream::Iterator::Compare::Base;

  Object constructor takes no arguments

• $compare->add_consolidator($iterator_a);

      An $iterator object must implement one of the following iterator classes
  
        Data::Range::Compare::Stream::Iterator::Consolidate
         
        Data::Range::Compare::Stream::Iterator::Compare::Asc
  
       my $boolean=$iterator_a->has_next
  
         Boolean value indicating if there are any more ranges
  
       my $result=$iterator_a->get_next;
  
         $result must implement one of the following result objects:
  
           Data::Range::Compare::Stream::Iterator::Consolidate::Result
  	   
           Data::Range::Compare::Stream::Iterator::Compare::Result

• while($compare->has_next) { do something }

  Must be implemented
  
  See: 
  
  Data::Range::Compare::Stream::Iterator::Compare::Asc

• my $result=$compare->get_next;

  Must be implemented
  
  See: 
  
  Data::Range::Compare::Stream::Iterator::Compare::Asc
  
  
  Suggested implementation:
  
  if $compare->has_next returns true
    
    Returns a instance of Data::Range::Compare::Stream::Iterator::Compare::Result

• my $count=$compare->get_column_count_human_readable;

  Returns a human readable count of the columns in the comparison object

• my $count=$compare->get_column_count;

  Returns the last index id of the iterator column counts

• my $range=$compare->get_current_row;

  Returns the range object that will be used in the $compare->get_next call

• my $boolean=$compare->iterators_empty;

  Returns false when all iterator objects in $compare are depleted

• my $result=$compare->get_next;

  Must be implemented
  
  See: 
  
  Data::Range::Compare::Stream::Iterator::Compare::Asc
  
  Suggested implementation
  
  if $compare->has_next returns true
  
    Returns an instance of Data::Range::Compare::Stream::Iterator::Compare::Result
