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;
