== Object Hierarchy
* Object
* GLib::Instantiatable
* GLib::Object
* Gst::Object
* Gst::Pad
== Instance Methods
+ --- caps
+ Gets the capabilities of the pad element.
+ * Returns: an array of Gst::Caps objects.
+
--- direction
This method returns the pad's direction (see ((<GstPadDirection|Gst::Pad#GstPadDirection>))).
* Returns: the pad's direction (see ((<GstPadDirection|Gst::Pad#GstPadDirection>))).
--- disabled?
Checks if the Gst::Pad::FLAG_DISABLED flag is set on the object.
* Returns: true if the flag is set, false otherwise.
+
+ --- each_caps { |caps| ... }
+ Calls the block for each capability of the pad,
+ passing a reference to the Gst::Caps object as parameter.
+ * Returns: always nil.
--- each_event_mask { |event_mask| ... }
Calls the block for each event mask from the pad, passing
a reference to the Gst::EventMask object as parameter.
* Returns: always nil.
--- each_format { |format| ... }
Calls the block for each supported format from the pad, passing
a reference to the Gst::Format object as parameter.
* Returns: always nil.
--- each_query_type { |query_type| ... }
Calls the block for each supported query from the pad, passing
a reference to the Gst::QueryType object as parameter.
* Returns: always nil.
--- event_masks
Gets the list of event masks from the pad.
* Returns: an array of Gst::EventMask objects.
--- formats
Gets the list of supported formats from the pad.
* Returns: an array of Gst::Format objects.
--- link(other_pad)
Links the current pad (source) to an other pad (sink).
* other_pad: a Gst::Pad.
* Returns: true if the pads have been linked, false otherwise.
--- name
This method returns the pad's name.
* Returns: the pad's name.
--- negotiating?
Checks if the Gst::Pad::FLAG_NEGOTIATING flag is set on the object.
* Returns: true if the flag is set, false otherwise.
--- pad_template
This method returns the Gst::PadTemplate object of this pad.
* Returns: the Gst::PadTemplate object of this pad.
--- provides_event_masks?
Checks if the pad supports event masks not handled by
the default event masks dispatcher.
* Returns: true if supported, false otherwise.
--- provides_formats?
Checks if the pad supports formats not handled by
the default format dispatcher.
* Returns: true if supported, false otherwise.
--- provides_query_types?
Checks if the pad supports query types not handled by

* Returns: true if supported, false otherwise.
--- query(query_type, format=Gst::Format::DEFAULT)
Performs a query on the pad.
* format: a format (see ((<GstFormat|Gst::Format#GstFormat>))).
* query_type: a query type (see ((<GstQueryType|Gst::QueryType#GstQueryType>))).
* Returns: the query result value, or nil if the query could not be performed.
--- query_types
Gets a list of supported queries that can be performed on the pad.
* Returns: an array of Gst::QueryType objects.
--- send_event(event)
Sends an event to the pad, through a Gst::Event object.
* event: a Gst::Event.
* Returns: true if the request event was successfully handled, false otherwise.
--- unlink(other_pad)
