A container of interfaces.

#include <interfacecontainer.h>
A container of interfaces.
To access the elements use an iterator. This implementation is thread save.

- OInterfaceIteratorHelper
cppu::OInterfaceContainerHelper::OInterfaceContainerHelper |
( |
::osl::Mutex & |
rMutex | ) |
|
Create an interface container.
- Parameters
-
rMutex | the mutex to protect multi thread access. The lifetime must be longer than the lifetime of this object. |
cppu::OInterfaceContainerHelper::~OInterfaceContainerHelper |
( |
| ) |
|
Release all interfaces.
All iterators must be destroyed before the container is destructed.
Inserts an element into the container.
The position is not specified, thus it is not specified in which order events are fired.
- Attention
- If you add the same interface more than once, then it will be added to the elements list more than once and thus if you want to remove that interface from the list, you have to call removeInterface() the same number of times. In the latter case, you will also get events fired more than once (if the interface is a listener interface).
- Parameters
-
rxIFace | interface to be added; it is allowed to insert null or the same interface more than once |
- Returns
- the new count of elements in the container
void cppu::OInterfaceContainerHelper::clear |
( |
| ) |
|
Clears the container without calling disposing().
void cppu::OInterfaceContainerHelper::disposeAndClear |
( |
const ::com::sun::star::lang::EventObject & |
rEvt | ) |
|
Call disposing on all object in the container that support XEventListener.
Than clear the container.
template<typename ListenerT , typename FuncT >
void cppu::OInterfaceContainerHelper::forEach |
( |
FuncT const & |
func | ) |
|
|
inline |
Executes a functor for each contained listener of specified type, e.g.
forEach<awt::XPaintListener>(...
.
If a com::sun::star::lang::DisposedException occurs which relates to the called listener, then that listener is removed from the container.
- Template Parameters
-
ListenerT | listener type |
FuncT | unary functor type, let your compiler deduce this for you |
- Parameters
-
func | unary functor object expecting an argument of type com::sun::star::uno::Reference<ListenerT> |
Return all interfaces added to this container.
sal_Int32 cppu::OInterfaceContainerHelper::getLength |
( |
| ) |
const |
Return the number of Elements in the container.
Only useful if you have acquired the mutex.
template<typename ListenerT , typename EventT >
void cppu::OInterfaceContainerHelper::notifyEach |
( |
void(ListenerT::*)(const EventT &) |
NotificationMethod, |
|
|
const EventT & |
Event |
|
) |
| |
|
inline |
Calls a UNO listener method for each contained listener.
The listener method must take a single argument of type EventT, and return void
.
If a com::sun::star::lang::DisposedException occurs which relates to the called listener, then that listener is removed from the container.
- Template Parameters
-
ListenerT | UNO event listener type, let your compiler deduce this for you |
EventT | event type, let your compiler deduce this for you |
- Parameters
-
NotificationMethod | Pointer to a method of a ListenerT interface. |
Event | Event to notify to all contained listeners |
Example:
awt::PaintEvent aEvent( static_cast< cppu::OWeakObject* >( this ), ... );
listeners.notifyEach( &XPaintListener::windowPaint, aEvent );

Removes an element from the container.
It uses interface equality to remove the interface.
- Parameters
-
rxIFace | interface to be removed |
- Returns
- the new count of elements in the container
