GI.Gst.Objects.Tracer

Contents

Description

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.

Synopsis

Exported types

newtype Tracer Source #

Memory-managed wrapper type.

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

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

noTracer :: Maybe Tracer Source #

A convenience alias for Nothing :: Maybe Tracer.

Properties

params

No description available in the introspection data.

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

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) Source #

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) Source #

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 () Source #

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

set tracer [ #params := value ]
