path::class::file::stat
Path::Class::File::Stat(3pm) User Contributed Perl Documentation Path::Class::File::Stat(3pm)
NAME
Path::Class::File::Stat - cache and compare stat() calls on a Path::Class::File object
SYNOPSIS
use Path::Class::File::Stat;
my $file = Path::Class::File::Stat->new('path','to','file');
# $file has all the magic of Path::Class::File
# sometime later
if ($file->changed)
{
# do something provocative
}
DESCRIPTION
Path::Class::File::Stat is a simple extension of Path::Class::File. Path::Class::File::Stat is useful in long-running programs (as under
mod_perl) where you might have a file handle opened and want to check if the underlying file has changed.
METHODS
Path::Class::File::Stat extends Path::Class::File objects in the following ways.
use_md5
Calling this method will attempt to load Digest::MD5 and use that instead of stat() for creating file signatures. This is similar to how
File::Modified works.
changed
Returns the previously cached File::stat object if the file's device number and inode number have changed, or if the modification time or
size has changed.
Returns 0 (false) otherwise.
While File::Modified uses a MD5 signature of the stat() of a file to determine if the file has changed, changed() uses a simpler (and
probably more naive) algorithm. If you need a more sophisticated way of determining if a file has changed, use the restat() method and
compare the cached File::stat object it returns with the current File::stat object.
Example of your own changed() logic:
my $oldstat = $file->restat;
my $newstat = $file->stat;
# compare $oldstat and $newstat any way you like
Or just use File::Modified instead.
restat
Re-cache the File::stat object in the Path::Class::File::Stat object. Returns the previously cached File::stat object.
The changed() method calls this method internally if changed() is going to return true.
