TAP::Parser::IteratorFactory

NAME

VERSION

SYNOPSIS

  use TAP::Parser::IteratorFactory;
  my $factory = TAP::Parser::IteratorFactory->new;
  my $iter = $factory->make_iterator(\*TEST);
  my $iter = $factory->make_iterator(\@array);
  my $iter = $factory->make_iterator(\%hash);

  my $line = $iter->next;

DESCRIPTION

METHODS

Class Methods

Creates a new factory class. Note: You currently don't need to instantiate a factory in order to use it.

"make_iterator"

Create an iterator. The type of iterator created depends on the arguments to the constructor:

  my $iter = TAP::Parser::Iterator->make_iterator( $filehandle );

Creates a stream iterator (see ``make_stream_iterator'').

  my $iter = TAP::Parser::Iterator->make_iterator( $array_reference );

Creates an array iterator (see ``make_array_iterator'').

  my $iter = TAP::Parser::Iterator->make_iterator( $hash_reference );

Creates a process iterator (see ``make_process_iterator'').

"make_stream_iterator"

Make a new stream iterator and return it. Passes through any arguments given. Defaults to a TAP::Parser::Iterator::Stream.

"make_array_iterator"

Make a new array iterator and return it. Passes through any arguments given. Defaults to a TAP::Parser::Iterator::Array.

"make_process_iterator"

Make a new process iterator and return it. Passes through any arguments given. Defaults to a TAP::Parser::Iterator::Process.  

SUBCLASSING

There are a few things to bear in mind when creating your own "ResultFactory":

1.

The factory itself is never instantiated (this may change in the future). This means that "_initialize" is never called.

Example

  package MyIteratorFactory;

  use strict;
  use vars '@ISA';

  use MyStreamIterator;
  use TAP::Parser::IteratorFactory;

  @ISA = qw( TAP::Parser::IteratorFactory );

  # override stream iterator
  sub make_stream_iterator {
    my $proto = shift;
    MyStreamIterator->new(@_);
  }

  1;
