## 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.

Gst::MiniObject::MiniObject | ( |  | ) | `[protected]`

Gst::MiniObject::MiniObject | ( | const Glib::Class & | mini_object_class | ) | `[explicit, protected]`

## Member Function Documentation

virtual Glib::RefPtr<Gst::MiniObject> Gst::MiniObject::copy_vfunc | ( |  | ) | const`[virtual]`

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

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

Glib::RefPtr<Gst::MiniObject> Gst::MiniObject::create_writable | ( |  | ) |

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:

  flag | The 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]`

Provides access to the underlying C GstMiniObject.

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

const GstMiniObject* Gst::MiniObject::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GstMiniObject.

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

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.

bool Gst::MiniObject::is_writable | ( |  | ) | const

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::reference | ( |  | ) | const

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

Sets the given bits.

Parameters:

  flag | The flag to set, can by any number of bits in guint32.

void Gst::MiniObject::swap | ( | MiniObject& | other | ) | `[protected]`

void Gst::MiniObject::unreference | ( |  | ) | const

void Gst::MiniObject::unset_flag | ( | guint | flag | ) |

Unsets the given bits.

Parameters:

  flag | The flag to unset, must be a single bit in guint32.
