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

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.

Methods

Overloaded methods

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, MonadIO m) => Text -> m (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 ]
