SYNOPSIS

10

FUNCTIONS

12   new
13           $replayable = new Fsdb::IO::Replayable(-writer_args => \@writer_args,
14               -reader_args => \@reader_args);
15           $writer = $replayable->writer;
16           $replayable->close;  # warning: close replayable, NOT writer
17           $reader = $replayable->reader;
18
19       Creates a buffer for Fsdb::IO objects that will run with bounded memory
20       usage.  After you close it, you can replay it one or more times by
21       opening readers.
22
23       Arguments to the new method:
24
25       -writer_args => @arref Gives arguments to pass to Fsdb::IO::Writer to
26       make a new stream.
27       -reader_args => @arref Gives arguments to pass to Fsdb::IO::Reader to
28       make a new stream.
29       -tmpdir => $dirname Specifies wher tmpfiles go.
30
31   writer
32           $writer = $replayable->writer;
33
34       Return a fsdb writer object.  If the file was written already, resets
35       it for rewriting.
36
37   close
38           $replayable->close;
39
40       Close the replayable for writing.  Closes the writer object, if any.
41       Allows reading to start.
42
43   reader
44           $reader = $replayable->reader;
45
46       Return a fsdb reader object to re-read the file.  Can be called once.
47
48       The caller is expected to close and discard any readers.
