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

set_params($self, @params);

Sets object parameters to user values. If set key doesn't exist in $self object, turn fatal error.

$self - Object or hash reference. @params - Key, value pairs.

set_params_pub

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 set public key doesn't exist in $self object, turn fatal error.

$self

Object or hash reference.

@params

Key, value pairs.

Returns undef.

set_split_params

my @other_params = set_split_params($self, @params);

Set object params and other returns.

$self

Object or hash reference.

@params

Key, value pairs.

Returns list of parameters.

split_params

my ($object_params_ar, $other_params_ar) = split_params($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";

# Output:
# Main params:
# * foo: bar
# Other params:
# * bad: value
