GI.Gst.Objects.Tracer

Tracing modules will subclass Tracer and register through gst_tracer_register(). Modules can attach to various hook-types - see gst_tracing_register_hook(). When invoked they receive hook specific contextual data, which they must not modify.

Since: 1.8

Exported types

newtype Tracer

Memory-managed wrapper type.

Constructors

Tracer (ManagedPtr Tracer)

Instances

GObject Tracer

Defined in GI.Gst.Objects.Tracer

Methods

gobjectType :: IO GType

HasParentTypes Tracer

Defined in GI.Gst.Objects.Tracer

type ParentTypes Tracer

Defined in GI.Gst.Objects.Tracer

type ParentTypes Tracer = Object ': (Object ': ([] :: [Type]))

class (GObject o, IsDescendantOf Tracer o) => IsTracer o

Type class for types which can be safely cast to Tracer, for instance with toTracer.

Instances

(GObject o, IsDescendantOf Tracer o) => IsTracer o

Defined in GI.Gst.Objects.Tracer

toTracer :: (MonadIO m, IsTracer o) => o -> m Tracer

Cast to Tracer, for types for which this is known to be safe. For general casts, use castTo.

noTracer :: Maybe Tracer

A convenience alias for Nothing :: Maybe Tracer.

Properties

params

No description available in the introspection data.

clearTracerParams :: (MonadIO m, IsTracer o) => o -> m ()

Set the value of the “params” property to Nothing. When overloading is enabled, this is equivalent to

clear #params

constructTracerParams :: IsTracer o => Text -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “params” property. This is rarely needed directly, but it is used by new.

getTracerParams :: (MonadIO m, IsTracer o) => o -> m (Maybe Text)

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

get tracer #params

setTracerParams :: (MonadIO m, IsTracer o) => o -> Text -> m ()

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

set tracer [ #params := value ]
