NAME

Net::Stomp::MooseHelpers::ReadTrace - class to read the output of Net::Stomp::MooseHelpers::TraceStomp

VERSION

version 1.2

SYNOPSIS

  my $reader = Net::Stomp::MooseHelpers::ReadTrace->new({
     trace_basedir => '/tmp/mq',
  });

  my @frames = $reader->sorted_frames('/queue/somewhere');

DESCRIPTION

Net::Stomp::MooseHelpers::TraceStomp and Net::Stomp::MooseHelpers::TraceOnly write STOMP frames to disk. This class helps you read them back.

ATTRIBUTES

trace_basedir

The directory from which frames will be read. Accepts strings and Path::Class::Dir objects.

METHODS

read_frame_from_filename

  my $stomp_frame = $reader->read_frame_from_filename('/a/path');

Given a filename (unrelated to "trace_basedir"), returns a Net::Stomp::Frame object parsed from it, using "read_frame_from_fh".

read_frame_from_fh

  my $stomp_frame = $reader->read_frame_from_fh($fh);

Given a filehandle (binmode it first!), returns a Net::Stomp::Frame object parsed from it. If the filehandle contains more than one frame, reads the first one and leaves the read position just after it.

If the file was not a dumped STOMP frame, this function may still return a frame, but the contents are probably going to be useless.

trace_subdir_for_destination

  my $dir = $reader->trace_subdir_for_destination($destination);

Returns a Path::Class::Dir object pointing at the (possibly non-existent) directory used to store frames for the given destination.

->trace_subdir_for_destination() is the same as ->trace_basedir.

sorted_filenames

  my @names = $reader->sorted_filenames();
  my @names = $reader->sorted_filenames($destination);

Given a destination (/queue/something or similar), returns all frame dump filenames found under the corresponding dump directory under "trace_basedir", sorted by filename (that is, by timestamp).

If you don't specify a destination, all filenames from all destinations will be returned.

clear_destination

  $reader->clear_destination();
  $reader->clear_destination($destination);

Given a destination (/queue/something or similar), removes all stored frames for it.

If you don't specify a destination, all frames for all destinations will be removed.

sorted_frames

  my @frames = $reader->sorted_frames();
  my @frames = $reader->sorted_frames($destination);

Same as "sorted_filenames", but returns the parsed frames instead of the filenames.
