Detailed Description

template<class ListenerT>
class cppuhelper::OInterfaceIteratorHelper4< ListenerT >

This is the iterator of an OInterfaceContainerHelper4.

Typically one constructs an instance on the stack for one firing session. It is not allowed to assign or copy an instance of this class.

Template Parameters

Constructor & Destructor Documentation

OInterfaceIteratorHelper4() [1/2]

template<class ListenerT >

cppuhelper::OInterfaceIteratorHelper4< ListenerT >::OInterfaceIteratorHelper4 ( std::unique_lock< std::mutex > &  rGuard, OInterfaceContainerHelper4< ListenerT > &  rCont_  )

inline

Create an iterator over the elements of the container.

The iterator copies the elements of the container. A change to the container during the lifetime of an iterator is allowed and does not affect the iterator-instance. The iterator and the container take cares themself for concurrent access, no additional guarding is necessary.

Remark: The copy is on demand. The iterator copy the elements only if the container change the contents...

Parameters

rCont	the container of the elements.
rGuard	this parameter only here to make that this container is accessed while locked

Member Function Documentation

hasMoreElements()

template<class ListenerT >

bool cppuhelper::OInterfaceIteratorHelper4< ListenerT >::hasMoreElements ( ) const

inline

Return true, if there are more elements in the iterator.

next()

template<class ListenerT >

const css::uno::Reference< ListenerT > & cppuhelper::OInterfaceIteratorHelper4< ListenerT >::next

Return the next element of the iterator.

Calling this method if hasMoreElements() has returned false, is an error.

remove()

template<class ListenerT >

void cppuhelper::OInterfaceIteratorHelper4< ListenerT >::remove

(

::std::unique_lock<::std::mutex > &

rGuard

)

Removes the current element (the last one returned by next()) from the underlying container.

Calling this method before next() has been called or calling it twice with no next() in between is an error.

Parameters

rGuard

this parameter only here to make that this container is accessed while locked
