GI.Gst.Structs.TimedValue

Structure for saving a timestamp and a value.

Exported types

newtype TimedValue

Memory-managed wrapper type.

Constructors

TimedValue (ManagedPtr TimedValue)

Instances

WrappedPtr TimedValue

Defined in GI.Gst.Structs.TimedValue

Methods

wrappedPtrCalloc :: IO (Ptr TimedValue)

wrappedPtrCopy :: TimedValue -> IO TimedValue

wrappedPtrFree :: Maybe (GDestroyNotify TimedValue)

tag ~ AttrSet => Constructible TimedValue tag

Defined in GI.Gst.Structs.TimedValue

Methods

new :: MonadIO m => (ManagedPtr TimedValue -> TimedValue) -> [AttrOp TimedValue tag] -> m TimedValue

newZeroTimedValue :: MonadIO m => m TimedValue

Construct a TimedValue struct initialized to zero.

noTimedValue :: Maybe TimedValue

A convenience alias for Nothing :: Maybe TimedValue.

Properties

timestamp

timestamp of the value change

getTimedValueTimestamp :: MonadIO m => TimedValue -> m Word64

Get the value of the “timestamp” field. When overloading is enabled, this is equivalent to

get timedValue #timestamp

setTimedValueTimestamp :: MonadIO m => TimedValue -> Word64 -> m ()

Set the value of the “timestamp” field. When overloading is enabled, this is equivalent to

set timedValue [ #timestamp := value ]

value

the corresponding value

getTimedValueValue :: MonadIO m => TimedValue -> m Double

Get the value of the “value” field. When overloading is enabled, this is equivalent to

get timedValue #value

setTimedValueValue :: MonadIO m => TimedValue -> Double -> m ()

Set the value of the “value” field. When overloading is enabled, this is equivalent to

set timedValue [ #value := value ]
