Glib::Flags(3)						User Contributed Perl Documentation					    Glib::Flags(3)

NAME
Glib::Flags DESCRIPTION
Glib maps flag and enum values to the nicknames strings provided by the underlying C libraries. Representing flags this way in Perl is an interesting problem, which Glib solves by using some cool overloaded operators. The functions described here actually do the work of those overloaded operators. See the description of the flags operators in the "This Is Now That" section of Glib for more info. HIERARCHY
Glib::Flags METHODS
scalar = $class->new ($a) o $a (scalar) Create a new flags object with given bits. This is for use from a subclass, it's not possible to create a "Glib::Flags" object as such. For example, my $f1 = Glib::ParamFlags->new ('readable'); my $f2 = Glib::ParamFlags->new (['readable','writable']); An object like this can then be used with the overloaded operators. scalar = $a->all ($b, $swap) o $b (scalar) o $swap (scalar) ref = $a->as_arrayref integer = $a->bool ($b, $swap) o $b (scalar) o $swap (integer) integer = $a->eq ($b, $swap) o $b (scalar) o $swap (integer) integer = $a->ge ($b, $swap) o $b (scalar) o $swap (integer) scalar = $a->intersect ($b, $swap) o $b (scalar) o $swap (scalar) integer = $a->ne ($b, $swap) o $b (scalar) o $swap (integer) scalar = $a->sub ($b, $swap) o $b (scalar) o $swap (scalar) scalar = $a->union ($b, $swap) o $b (scalar) o $swap (scalar) scalar = $a->xor ($b, $swap) o $b (scalar) o $swap (scalar) SEE ALSO
