The property probe is a way to autodetect allowed values for a GObject property. Its primary use is to autodetect device-names in several elements.
The interface is implemented by many hardware sources and sinks.

| bool Gst::PropertyProbe::needs_probe | ( | const Glib::ustring & | name | ) | const |
Same as gst_property_probe_needs_probe().
| name | The name of the property to check. |
true if the property needs a new probe, false if not. | bool Gst::PropertyProbe::needs_probe | ( | const GParamSpec * | pspec | ) | const |
Checks whether a property needs a probe.
This might be because the property wasn't initialized before, or because host setup changed. This might be, for example, because a new device was added, and thus device probing needs to be refreshed to display the new device.
| pspec | A ParamSpec that identifies the property to check. |

| Glib::ValueArray Gst::PropertyProbe::probe_and_get_values | ( | const GParamSpec * | pspec | ) |
Check whether the given property requires a new probe.
If so, fo the probe. After that, retrieve a value list. Meant as a utility function that wraps the above functions.
| pspec | The ParamSpec property identifier. |
| void Gst::PropertyProbe::probe_property | ( | const Glib::ustring & | name | ) |
Runs a probe on the property specified by name.

Runs a probe on the property specified by pspec.
| pspec | ParamSpec of the property. |

A Glib::wrap() method for this object.
