NAME
Clutter::Interval - An object holding an interval of two valuesSYNOPSIS
my $interval = Clutter::Interval->new('Glib::Int', 0, 11); my $value = $interval->compute_value(0.5);
DESCRIPTION
Clutter::Interval is a simple object providing a strongly-typed storage for a interval between two values.Note: Once a Clutter::Interval for a specific type has been instantiated the Clutter::Interval value-type property cannot be changed anymore.
Clutter::Interval is used by #ClutterAnimation to define the interval of values that an implicit animation should tween over.
Note: Currently, you cannot subclass a Clutter::Interval to override the interval validation and the value computation; this requires additional support inside the Glib Perl bindings that is not currently available.

METHODS
interval = Clutter::Interval->new ($type, $initial=undef, $final=undef)
- •
- $type (string)
- •
- $initial (scalar)
- •
- $final (scalar)
Creates a new Clutter::Interval, representing an interval of values with the given type
value = $interval->compute_value ($factor)
- •
- $factor (double)
Computes the value of the interval given the factor
scalar = $interval->get_final_value
Gets the final value of the interval$interval->set_final_value ($final)
- •
- $final (scalar)
Sets the final value of the interval
scalar = $interval->get_initial_value
Gets the initial value of the interval$interval->set_initial_value ($initial)
- •
- $initial (scalar)
Sets the initial value of the interval
(initial, final) = $interval->get_interval ()
Gets the initial and final values of the interval$interval->set_interval ($initial, $final)
- •
- $initial (scalar)
- •
- $final (scalar)
Sets the initial and final values of the interval. The values must be compatible with the type set when creating the interval itself
boolean = $interval->validate ($pspec)
- •
- $pspec (Glib::ParamSpec)
string = $interval->get_value_type
Gets the type of the values inside the intervalPROPERTIES
- 'value-type' (GType : readable / writable / construct-only)
- The type of the values in the interval
