@Generated("io.github.jwharm.JavaGI")
public class SystemClock
extends Clock

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

public SystemClock(MemorySegment address)

Create a SystemClock proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Method Details

getType

public static Type getType()

Get the GType of the SystemClock class

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected SystemClock asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class Clock

obtain

public static Clock 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

public static void setDefault(@Nullable
 @Nullable Clock newClock)

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 - a GstClock

builder

public static SystemClock.Builder<? extends SystemClock.Builder> builder()

A SystemClock.Builder object constructs a SystemClock with the specified properties. Use the various set...() methods to set properties, and finish construction with SystemClock.Builder.build().
