# 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;
