NAME
    Class::Utils - Class utilities.

SYNOPSIS
     use Class::Utils qw(set_params set_split_params);

     set_params($self, @params);
     set_params_pub($self, @params);
     my @other_params = set_split_params($self, @params);
     my ($object_params_ar, $other_params_ar) = split_params($object_keys_ar, @params);

SUBROUTINES
    "set_params($self, @params)"
             Sets object parameters to user values.
             If setted key doesn't exist in $self object, turn fatal error.
             $self - Object or hash reference.
             @params - Key, value pairs.

    "set_params_pub($self, @params)"
             Sets object parameters to user values. Only public arguments.
             Private arguments are defined by '_' character on begin of key and will be
             skip.
             If setted public key doesn't exist in $self object, turn fatal error.
             $self - Object or hash reference.
             @params - Key, value pairs.

    "set_split_params($self, @params)"
             Set object params and other returns.
             $self - Object or hash reference.
             @params - Key, value pairs.
             Returns array with other parameters.

    "split_params($object_keys_ar, @params)"
             Split params to list of object params and other params.
             Returns array with two values. First is reference to array with object
             parameters. Second in reference to array with other parameters.

ERRORS
     set_params():
             Unknown parameter '%s'.

     set_params_pub():
             Unknown parameter '%s'.

EXAMPLE1
     use strict;
     use warnings;

     use Class::Utils qw(set_params);

     # Hash reference with default parameters.
     my $self = {
            'test' => 'default',
     };

     # Set params.
     set_params($self, 'test', 'real_value');

     # Print 'test' variable.
     print $self->{'test'}."\n";

     # Output:
     # real_value

EXAMPLE2
     use strict;
     use warnings;

     use Class::Utils qw(set_params);

     # Hash reference with default parameters.
     my $self = {};

     # Set bad params.
     set_params($self, 'bad', 'value');

     # Turn error >>Unknown parameter 'bad'.<<.

EXAMPLE3
     use strict;
     use warnings;

     use Class::Utils qw(set_params_pub);

     # Hash reference with default parameters.
     my $self = {
             'public' => 'default',
     };

     # Set params.
     set_params_pub($self,
             'public' => 'value',
             '_private' => 'value',
     );

     # Print 'test' variable.
     print $self->{'public'}."\n";

     # Output:
     # value

EXAMPLE4
     use strict;
     use warnings;

     use Class::Utils qw(set_split_params);

     # Hash reference with default parameters.
     my $self = {
            'foo' => undef,
     };

     # Set bad params.
     my @other_params = set_split_params($self,
            'foo', 'bar',
            'bad', 'value',
     );

     # Print out.
     print "Foo: $self->{'foo'}\n";
     print join ': ', @other_params;
     print "\n";

     # Output:
     # Foo: bar
     # bad: value

EXAMPLE5
     use strict;
     use warnings;

     use Class::Utils qw(split_params);

     # Example parameters.
     my @params = qw(foo bar bad value);

     # Set bad params.
     my ($main_params_ar, $other_params_ar) = split_params(['foo'], @params);

     # Print out.
     print "Main params:\n";
     print "* ".(join ': ', @{$main_params_ar});
     print "\n";
     print "Other params:\n";
     print "* ".(join ': ', @{$other_params_ar});
     print "\n";
