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
