Package org.freedesktop.gstreamer.gst
Class SystemClock
- All Implemented Interfaces:
Proxy
- Direct Known Subclasses:
AudioClock
The GStreamer core provides a GstSystemClock based on the system time.
Asynchronous callbacks are scheduled from an internal thread.
Clock implementors are encouraged to subclass this systemclock as it implements the async notification.
Subclasses can however override all of the important methods for sync and async notifications to implement their own callback methods or blocking wait operations.

Constructor Details
-
SystemClock
Create a SystemClock proxy instance for the provided memory address.- Parameters:
address- the memory address of the native object
-
SystemClock
public SystemClock()Creates a new SystemClock.
-
-
Method Details
-
getType
-
getMemoryLayout
The memory layout of the native struct.- Returns:
- the memory layout
-
asParent
Returns this instance as if it were its parent type. This is mostly synonymous to the Javasuperkeyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" withsuper.methodName()doesn't work, because it invokes the overridden function pointer again. To chain up, callasParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type. -
obtain
Get a handle to the default system clock. The refcount of the clock will be increased so you need to unref the clock after usage.- Returns:
- the default clock.
MT safe.
-
setDefault
Sets the default system clock that can be obtained with gst_system_clock_obtain().This is mostly used for testing and debugging purposes when you want to have control over the time reported by the default system clock.
MT safe.
- Parameters:
newClock- aGstClock- Since:
- 1.4
-
builder
ASystemClock.Builderobject constructs aSystemClockwith the specified properties. Use the variousset...()methods to set properties, and finish construction withSystemClock.Builder.build().- Returns:
- the builder object
-
