=head1 NAME
Lintian::DepMap::Properties - Dependencies with properties map/tree creator
=head1 SYNOPSIS
use Lintian::DepMap::Properties;
my $map = Lintian::DepMap::Properties->new;
=head1 DESCRIPTION
Lintian::DepMap::Properties is a simple layer between Lintian::DepMap and the
application allowing nodes to have application-defined properties.
=over 4
=item add(node, [dependencies], [ref to property])
Adds a node with possibly one or more dependencies and sets the C<node>'s
property to the ref, if defined. The property must be a reference (it
can be to a hash, an array, a function, an object, etc) and must be the
last argument given to the method.
E.g.
$map->add('foo', {name => 'John Doe', age => 20});
=cut
#'
sub add {
my $self = shift;
my $ref = pop;
if (not defined $ref) {
# do nothing if not defined
} elsif (not ref($ref)) {
push @_, $ref;
} else {
$self->{'properties'}{$_[0]} = $ref;
}
return $self->SUPER::add(@_);
}
=item addp(node[, prefix, dependency[, dependency...]], [ref to property])
Adds the given C<node> to the map marking any third or more parameters,
after prefixing them with C<prefix>, as its dependencies and sets the
C<node>'s property to the ref, if defined. See add()'s description for
more information about properties. E.g.
# pA and pB have no dependency:
$map->addp('pA', {name => 'John Doe'});
$map->addp('pB', {name => 'Jane Doe'});
# Df depends on pA and pB:
$map->addp('Df', 'p', 'A', 'B', {name => 'Doe Family'});
=cut
sub addp {
my $self = shift;
my $ref = pop;
if (not defined $ref) {
# do nothing if not defined
} elsif (not ref($ref)) {
push @_, $ref;
} else {
$self->{'properties'}{$_[0]} = $ref;
}
return $self->SUPER::addp(@_);
}
=item getp(node)
Returns the reference to the given C<node>'s properties.
E.g.
# prints John Doe
print $map->getp('foo')->{'name'};
# changes the value of 'name'
$map->getp('foo')->{'name'} = 'Jane Doe';
# prints Jane Doe
print $map->getp('foo')->{'name'};
=cut
#'
sub getp {
my $self = shift;
my $node = shift;
return $self->{'properties'}{$node};
}
