Glib::RefPtr< Gst::MiniObjectwrap (GstMiniObject* object, bool take_copy=false)

Detailed Description

This is a base class for some gstreamermm objects.

It is similar to Glib::Object but has no GObject property or signal support.

Member Function Documentation

Virtual function called when the Gst::MiniObject needs to be copied.

Reimplemented in Gst::Event, Gst::Message, and Gst::Query.

Checks if a mini-object is writable.

If not, a writable copy is made and returned. This gives away the reference to the original mini object, and returns a reference to the new object.

MT safe

Returns:
A mini-object (possibly the same pointer) that is writable.

Reimplemented in Gst::Event, Gst::Message, Gst::Buffer, Gst::Query, and Gst::BufferList.

virtual void Gst::MiniObject::finalize_vfunc ( ) [virtual]

Virtual function called when the Gst::MiniObject is about to be finalized.

Reimplemented in Gst::Event, Gst::Message, and Gst::Query.

bool Gst::MiniObject::flag_is_set ( guint  flag) const

Checks to see if the given flag is set.

Parameters:
flagThe flag to check for.
guint Gst::MiniObject::get_flags ( ) const

Returns the entire set of flags for the mini-object.

Returns:
The Gst::MiniObject flags.
GstMiniObject* Gst::MiniObject::gobj ( ) [inline]
const GstMiniObject* Gst::MiniObject::gobj ( ) const [inline]
GstMiniObject* Gst::MiniObject::gobj_copy ( )

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

Reimplemented in Gst::DiscovererVideoInfo, Gst::DiscovererAudioInfo, Gst::DiscovererContainerInfo, Gst::DiscovererStreamInfo, Gst::Event, Gst::Message, Gst::Query, Gst::Buffer, Gst::DiscovererInfo, and Gst::BufferList.

Checks if a mini-object is writable.

A mini-object is writable if the reference count is one and the Gst::MINI_OBJECT_FLAG_READONLY flag is not set. Modification of a mini-object should only be done after verifying that it is writable.

MT safe

Returns:
true if the object is writable.

Reimplemented in Gst::BufferList.

void Gst::MiniObject::set_flag ( guint  flag)

Sets the given bits.

Parameters:
flagThe flag to set, can by any number of bits in guint32.
void Gst::MiniObject::swap ( MiniObject other) [protected]
void Gst::MiniObject::unset_flag ( guint  flag)

Unsets the given bits.

Parameters:
flagThe flag to unset, must be a single bit in guint32.
