Member Function Documentation

Glib::RefPtr<Gst::Context> Gst::Context::copy ( )

Creates a copy of the context.

Returns a copy of the context.

Returns: A new copy of context.

MT safe.

Glib::RefPtr<Gst::Context> Gst::Context::copy ( ) const

Creates a copy of the context.

Returns a copy of the context.

Returns: A new copy of context.

MT safe.

static Glib::RefPtr<Context> Gst::Context::create	(	const Glib::ustring &	context_type,
		bool	persistent
	)

static

Glib::ustring Gst::Context::get_context_type ( ) const

Get the type of context.

Returns: The type of the context.

GstContext* Gst::Context::gobj ( )

Provides access to the underlying C instance.

const GstContext* Gst::Context::gobj ( ) const

Provides access to the underlying C instance.

GstContext* Gst::Context::gobj_copy ( ) const

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

bool Gst::Context::has_context_type ( const Glib::ustring & context_type ) const

Checks if context has context_type.

Parameters

context_type Context type to check.

Returns: true if context has context_type.

bool Gst::Context::is_persistent ( ) const

Check if context is persistent.

Returns: true if the context is persistent.

void Gst::Context::operator delete	(	void *	,
		std::size_t
	)

protected

void Gst::Context::reference ( ) const

Increment the reference count for this object.

You should never need to do this manually - use the object via a RefPtr instead.

void Gst::Context::unreference ( ) const

Decrement the reference count for this object.

You should never need to do this manually - use the object via a RefPtr instead.

Gst::Structure Gst::Context::writable_structure ( ) const

Get a writable version of the structure.

Returns: The structure of the context. The structure is still owned by the event, which means that you should not free it and that the pointer becomes invalid when you free the event. This function checks if context is writable.

Glib::RefPtr< Gst::Context > wrap	(	GstContext *	object,
		bool	take_copy = `false`
	)

A Glib::wrap() method for this object.

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns: A C++ instance that wraps this C instance.
