Detailed Description

A class that represents a double range (min - max).

Gst::DoubleRange is used to use to store a double precision floating point 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::DoubleRange> value;
 value.init(Glib::Value<Gst::DoubleRange>::value_type());
 value.set(Gst::DoubleRange(44.1, 48.0));

 Gst::Structure structure("my-structure");
 structure.set_field("rate", value);
 ...
 Glib::ValueBase gst_value;
 structure.get_field("rate", gst_value);
 Gst::DoubleRange range(gst_value);
 double min = range.min;
 ...
