NAME

6       IO::Handle::Iterator - Iterator based read handle
7

SYNOPSIS

9           IO::Handle::Iterator->new(sub {
10               return $next_line; # or undef on eof
11           });
12

DESCRIPTION

14       This class lets you define a read handle with a few fallback methods
15       (like "read") using a single callback that behaves like "getline".
16
17       This is similar but much simpler than:
18
19           IO::Handle::Prototype::Fallback->new(
20               __read => sub { ... },
21           );
22
23       The reason being that the IO::Handle::Prototype::Fallback
24       implementation will try its very best to behave correctly (i.e. respect
25       the value of $/), whereas this implementation assumes it's fine to
26       return things that aren't exactly lines from "getline", so the values
27       are just passed through.
28

READ BUFFERING

30       When a method that requires buffering is invoked the handle is
31       reblessed to a subclass which handles buffering.
32
33       Calling "getline" again on this object will return the value of the
34       buffer and return to the normal iterator class.
