NAME

       TAP::Parser::IteratorFactory - Internal TAP::Parser Iterator

VERSION

       Version 3.17

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

       This is a factory class for simple iterator wrappers for arrays, filehandles, and hashes.  Unless you're subclassing, you probably won't
       need to use this module directly.

METHODS

   Class Methods
       "new"

       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

       Please see "SUBCLASSING" in TAP::Parser for a subclassing overview.

       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;
