public class TimedValueControlSource
extends ControlSource

Timed value control source base class.

See upstream documentation at https://gstreamer.freedesktop.org/data/doc/gstreamer/stable/gstreamer-libs/html/GstTimedValueControlSource.html

Base class for ControlSource that use time-stamped values.

When overriding bind, chain up first to give this bind implementation a chance to setup things.

All functions are MT-safe.

TimedValueControlSource

protected TimedValueControlSource(TimedValueControlSource.Handle handle,
                                  boolean needRef)

Method Detail

set

public boolean set(long timestamp,
                   double value)

Parameters:

timestamp - the time the control-change is scheduled for

value - the control value

Returns:

false if the value could not be set

setFromList

public boolean setFromList(List<ControlSource.TimedValue> timedValues)

Sets multiple timed values at once.

Parameters:

timedValues - a list of TimedValue

Returns:

false if the values could not be set

getAll

public List<ControlSource.TimedValue> getAll()

Returns a copy of the list of TimedValue for the given property.

Returns:

a list of TimedValue

unset

public boolean unset(long timestamp)

Used to remove the value of given controller-handled property at a certain time.

Parameters:

timestamp - the time the control-change should be removed from

Returns:

FALSE if the value couldn't be unset (i.e. not found)

unsetAll

public void unsetAll()

Used to remove all time-stamped values of given controller-handled property.

getCount

public int getCount()

Get the number of control points that are set.

Returns:

the number of control points that are set

invalidateCache

public void invalidateCache()

Reset the controlled value cache.
