        public void addToRunLoopForMode​(NSRunLoop runloop,
                                java.lang.String mode)
        Adds the receiver to the given run-loop and mode. Unless paused, it will fire every vsync until removed. Each object may only be added to a single run-loop, but it may be added in multiple modes at once. While added to a run-loop it will implicitly be retained.

      • duration

        public double duration()

      • frameInterval

        public long frameInterval()
        Defines how many display frames must pass between each time the display link fires. Default value is one, which means the display link will fire for every display frame. Setting the interval to two will cause the display link to fire every other display frame, and so on. The behavior when using values less than one is undefined. DEPRECATED - use preferredFramesPerSecond.

      • invalidate

        public void invalidate()
        Removes the object from all runloop modes (releasing the receiver if it has been implicitly retained) and releases the 'target' object.

      • isPaused

        public boolean isPaused()
        When true the object is prevented from firing. Initial state is false.

      • setPaused

        public void setPaused​(boolean value)
        When true the object is prevented from firing. Initial state is false.

      • preferredFramesPerSecond

        public long preferredFramesPerSecond()
        Defines the desired callback rate in frames-per-second for this display link. If set to zero, the default value, the display link will fire at the native cadence of the display hardware. The display link will make a best-effort attempt at issuing callbacks at the requested rate.

      • removeFromRunLoopForMode

        public void removeFromRunLoopForMode​(NSRunLoop runloop,
                                     java.lang.String mode)
        Removes the receiver from the given mode of the runloop. This will implicitly release it when removed from the last mode it has been registered for.

      • setFrameInterval

        public void setFrameInterval​(long value)
        Defines how many display frames must pass between each time the display link fires. Default value is one, which means the display link will fire for every display frame. Setting the interval to two will cause the display link to fire every other display frame, and so on. The behavior when using values less than one is undefined. DEPRECATED - use preferredFramesPerSecond.

      • setPreferredFramesPerSecond

        public void setPreferredFramesPerSecond​(long value)
        Defines the desired callback rate in frames-per-second for this display link. If set to zero, the default value, the display link will fire at the native cadence of the display hardware. The display link will make a best-effort attempt at issuing callbacks at the requested rate.

      • targetTimestamp

        public double targetTimestamp()
        The next timestamp that the client should target their render for.

      • timestamp

        public double timestamp()
        The current time, and duration of the display frame associated with the most recent target invocation. Time is represented using the normal Core Animation conventions, i.e. Mach host time converted to seconds.
