NAME
    Util::Properties - Java.util.properties like class

DESCRIPTION
    rimplement something like ava.util.Properties API.

    The main differences with CPAN existant Config::Properties and
    Data::Properties is file locking & autoload/autosave features

SYNOPSIS
use Util::Properties;

my $prop = Util::Properties->new({file=>'file.properties'});
my $xyz=$prop->prop_get('x.y.z');
$prop->prop_set('w', -1);
$prop->save();

FUNCTIONS
METHODS
  Creators
   my $prop=Util::Properties->new()
   my $prop=Util::Properties->new(filename)
   my $prop=Util::Properties->new(\%h)
   my $prop=Util::Properties->new(\$Util::Properties)
    Create a new prop system from either:

    empty
    filename
    hash ref (key=>values will be taken as property name/value)
    a copy constructor from another Util::Properties object;

  Accessors/Mutators
   $prop->name([$val])
    Get/set a name for the set of prperty (mainly used for debugging or code
    clarity purpose

   $prop->file_ismirrored([val])
    Get/set (set if an argument is passed) a boolean value to determine if
    the file is to be file with property (if any is defined) is to be kept
    coherent with the data. This mean that any set of property will be
    mirrored on the file, and before any get, the file time stamp will be
    check to see if the data has changed into the file.

   $prop->file_name([path])
    Get/set the filename

   $prop->file_md5([hexval])
    Get/set the md5 of the file

   $prop->file_locker(bool|\$LockFile::Simple);
    Set if a file locker is to be used (or a file locker is you do not wish
    to use the default). A die will be thrown if locking fails

   $prop->file_locker();
    Get the file locker (or undef).

   $prop->file_isghost([val])
    get/set is it is possible for the file not to exist (in this case, no
    problem not to save...)

  Properties values
   $prop->prop_get(key)
    get property defined by key;

   $prop->prop_set(key, value)
    Set a property

   $prop->prop_list
    return a hash with all the properties

   $prop->prop_clean
    Clean the properties list;

   $prop->isEmpty();
    return true if the properties does not contain any fields

  I/O
   $prop->load()
    load properties from $prop->file_name

   $prop->save()
    Save properties from $prop->file_name (comment have been forgotten)

EXPORT
   $DEFAULT_FILE_LOCKER
    If a file_locker is to be defined by default creator [default is 1]

   $DEFAULT_FILE_ISMIRRORED
    If data in memory must be consistent with file (based on file
    maodification time) [default is 1]

   $VERBOSE
    verbose level;

TODO
   implement a '+=' notation (to have mult lines defined properties)
prop.one=some
prop.one+=thing

   implement a dependencies between properties
prop.one=something
prop.two=other/${prop.one}-thing
