| typedef sigc::slot< bool, const Glib::RefPtr<Gst::PluginFeature>& > Gst::PluginFeature::SlotFilter | 
For example, bool on_filter(const Glib::RefPtr<Gst::PluginFeature>& feature);.
The filter function should return true if the feature is a match, false otherwise.

Checks whether the given plugin feature is at least the required version.
| min_major | Minimum required major version. | 
| min_minor | Minimum required minor version. | 
| min_micro | Minimum required micro version. | 
true if the plugin feature has at least the required version, otherwise false. | Glib::RefPtr<Gst::Plugin> Gst::PluginFeature::get_plugin | ( | ) | const | 
Get the plugin that provides this feature.
nullptr. Unref with Gst::Object::unref() when no longer needed. | Glib::ustring Gst::PluginFeature::get_plugin_name | ( | ) | const | 
Get the name of the plugin that provides this feature.
nullptr if the feature is not associated with a plugin. | guint Gst::PluginFeature::get_rank | ( | ) | const | 
Gets the rank of a plugin feature.

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.
| Glib::RefPtr<Gst::PluginFeature> Gst::PluginFeature::load | ( | ) | 
Loads the plugin containing feature if it's not already loaded.
feature is unaffected; use the return value instead.
Normally this function is used like this:

 | noexcept | 
| void Gst::PluginFeature::set_rank | ( | guint | rank | ) | 
Specifies a rank for a plugin feature, so that autoplugging uses the most appropriate feature.
| rank | Rank value - higher number means more priority rank. |

| object | The C instance. | 
| take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |
