= class Gst::ClockEntry
A wrapper for GstClockID, used to create and start timers
on Gst::Clock objects.
== Object Hierarchy
* Object
* GLib::Boxed
* Gst::ClockEntry
== Class Methods
--- Gst::ClockEntry.new(clock, time, interval=nil)
Creates a new Gst::ClockEntry object based on the given Gst::Clock.
Two types of Gst::ClockEntry objects can be created:
- The timer will be issued after Gst::ClockEntry#wait
- or Gst::ClockEntry#wait_async.
- * One-shot: if anInterval is ommited or nil, the entry will trigger a single shot notification, at the requested aTime (in nanoseconds); Periodic: if anInterval is not nil, the timer entry will trigger a periodic notification, starting at aTime (in nanoseconds), and be fired with the given interval (also in nanoseconds).
+ * One-shot: if the interval is ommited or nil, the entry will trigger a single shot notification, at the requested time (in nanoseconds);
+ * Periodic: if the interval is not nil, the timer entry will trigger a periodic notification, starting at time (in nanoseconds), and be fired with the given interval (also in nanoseconds).
+ The timer will be issued after Gst::ClockEntry#wait or
+ Gst::ClockEntry#wait_async.
* time: a time period, in nanoseconds.
* clock: a Gst::Clock.
* interval: an interval period, in nanoseconds.
* Returns: a new Gst::ClockEntry object.
== Instance Methods
--- clock
This method returns the owner clock of the entry, as a Gst::Clock object.
* Returns: the owner clock of the entry, as a Gst::Clock object.
--- interval
This method returns the interval of the entry (in nanoseconds), or 0 if the entry is not periodic.
* Returns: the interval of the entry (in nanoseconds), or 0 if the entry is not periodic.
--- periodic?
This method returns true if the entry is periodic, false otherwise.
* Returns: true if the entry is periodic, false otherwise.
--- single_shot?
This method returns true if the entry is single-shot, false otherwise.
* Returns: true if the entry is single-shot, false otherwise.
--- status
- This method returns the status of the entry (see GstClockEntryStatus).
- * Returns: the status of the entry (see GstClockEntryStatus).
+ This method returns the status of the entry (see Gst::ClockEntry::Status).
+ * Returns: the status of the entry (see Gst::ClockEntry::Status).
--- time
This method returns the requested time of the entry, in nanoseconds.
* Returns: the requested time of the entry, in nanoseconds.
--- unlock
Unlocks the entry.
* Returns: self.
--- unschedule
Cancels an outstanding async notification request.
* Returns: self.
--- wait
Performs a blocking wait on the entry.
- * Returns: a return code (see GstClockReturn).
+ * Returns: a return code (see ((<GstClockReturn|Gst::Clock#GstClockReturn>))).
--- wait_async { |clock, time, clock_entry| ... }
Registers a block code, which will be called passing references
to the Gst::Clock, the time (in nanoseconds) and the Gst::ClockEntry as
parameters.
* Returns: a return code (see ((<GstClockReturn|Gst::Clock#GstClockReturn>))).
