NAME

Petal::Cache::Memory - Caches generated subroutines in memory.

SYNOPSIS

  use Petal::Cache::Memory;
  my $coderef = Petal::Cache::Memory->get ('foo.html');
  unless (defined $coderef)
  {
    $coderef = complicated_long_compute_thing();
    Petal::Cache::Memory->set ($coderef);
  }

DESCRIPTION

  A simple cache module to avoid re-compiling the Perl
  code from the Perl data at each request

METHODS

All the methods are static methods.

$class->get ($file);

Returns the cached subroutine if its last modification time is more recent than the last modification time of the template, returns undef otherwise

$class->set ($file, $code);

Sets the cached code for $file.

$class->is_ok ($file);

Returns TRUE if the cache is still fresh, FALSE otherwise.

$class->cached_mtime ($file);

Returns the last modification date of the cached data for $file

$class->current_mtime ($file);

Returns the last modification date for $file

$class->compute_key ($file);

Computes a cache 'key' for $file, which should be unique. (Well, currently an MD5 checksum is used, which is not *exactly* unique but which should be good enough)
