## Detailed Description

A class that represents an integer range (min - max).

Gst::IntRange is used to store an integer range in Gst::Structures of Gst::Caps as a value representing a property (see GStreamer Application Development Manual section 8.2.2 and GstValue docs). When the value is set, it is transformed to a GStreamer GType so retrieving the value is a bit different. The class can be used in setting and getting a Gst::Structure field like so:

     Glib::Value<Gst::IntRange> value;
     value.init(Glib::Value<Gst::IntRange>::value_type());
     value.set(Gst::IntRange(8000, 50000));

     Gst::Structure structure("my-structure");
     structure.set_field("rate", value);
     ...
     Glib::ValueBase gst_value;
     structure.get_field("rate", gst_value);
     Gst::IntRange range(gst_value);
     int max = range.max;
     ...
