## Detailed Description

### template<typename T>
class Gst::AtomicQueue< T >

The Gst::AtomicQueue object implements a queue that can be used from multiple threads without performing any blocking operations.

## Constructor & Destructor Documentation

## § AtomicQueue()

template <typename T >

Gst::AtomicQueue< T >::AtomicQueue | ( |  | ) |
| protected

## Member Function Documentation

## § create()

template <typename T >

static Glib::RefPtr<Gst::AtomicQueue<T> > Gst::AtomicQueue< T >::create | ( | guint | initial_size | ) |
| inlinestatic

## § gobj() [1/2]

template <typename T >

const GstAtomicQueue* Gst::AtomicQueue< T >::gobj | ( |  | ) | const
| inline

Provides access to the underlying C instance.

## § gobj() [2/2]

template <typename T >

GstAtomicQueue* Gst::AtomicQueue< T >::gobj | ( |  | ) |
| inline

Provides access to the underlying C instance.

## § gobj_copy()

template <typename T >

GstAtomicQueue* Gst::AtomicQueue< T >::gobj_copy | ( |  | ) | const
| inline

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

## § length() [1/2]

template <typename T >

guint Gst::AtomicQueue< T >::length | ( |  | ) |
| inline

Get the amount of items in the queue.

Returns
  The number of elements in the queue.

## § length() [2/2]

template <typename T >

guint Gst::AtomicQueue< T >::length | ( |  | ) | const
| inline

Get the amount of items in the queue.

Returns
  The number of elements in the queue.

## § operator delete()

template <typename T >

void Gst::AtomicQueue< T >::operator delete | ( | void * | ,
|  | std::size_t |
| ) |  |
| protected

## § peek()

template <typename T >

T Gst::AtomicQueue< T >::peek | ( |  | ) |
| inline

Peek the head element of the queue without removing it from the queue.

Returns
  The head element of queue.

Exceptions

  std::runtime_error | if the queue is empty.

## § pop()

template <typename T >

T Gst::AtomicQueue< T >::pop | ( |  | ) |
| inline

Get the head element of the queue.

Returns
  The head element of queue.

Exceptions

  std::runtime_error | if the queue is empty.

## § push()

template <typename T >

void Gst::AtomicQueue< T >::push | ( | const T & | data | ) |
| inline

Append data to the tail of the queue.

Parameters

  data | The data.

## § reference()

template <typename T >

void Gst::AtomicQueue< T >::reference | ( |  | ) | const
| inline

Increment the reference count for this object.

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

## § unreference()

template <typename T >

void Gst::AtomicQueue< T >::unreference | ( |  | ) | const
| inline

Decrement the reference count for this object.

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

## Friends And Related Function Documentation

## § wrap()

template <typename T >

Glib::RefPtr< Gst::AtomicQueue< T > > wrap | ( | GstAtomicQueue< T > * | object,
|  | bool | take_copy = `false`
| ) |  |
| related

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.
