7       file that serves as an output stream.

12

SYNOPSIS

14           use Test2::Harness::Util::File::Stream;
15
16           my $stream = Test2::Harness::Util::File::Stream->new(name => 'path/to/file');
17
18           # Read some lines
19           my @lines = $stream->poll;
20
21           ...
22
23           # Read more lines, if any.
24           push @lines => $stream->poll;
25

29       These can be passed in as construction arguments if desired.
30
31       $bool = $stream->use_write_lock
32       $stream->use_write_lock($bool)
33           Lock the file for every "write()" operation.
34
35       $bool = $stream->tail
36           Start near the end of the file and only poll for updates appended
37           to it.
38

METHODS

40       See Test2::Harness::File for additional methods.
41
42       @lines = $stream->read()
43           Read all lines from the beginning. Every time it is called it
44           returns ALL lines.
45
46       @lines = $stream->poll()
47       @lines = $stream->poll(max => $int)
48           Poll for lines. This is an iterator, it should not return the same
49           line more than once, you can call it multiple times to get any
50           additional lines that have been added since the last poll.
51
52       $stream->write(@content)
53           Append @content to the file.
