A class used to retrieve multiple reference counted elements in a thread safe way.
Gst::Iterator iterates specifically through elements that are reference counted and therefore dereferencing the elements of the iterator yields a Glib::RefPtr<> to the C++ element type.
| Gst::Iterator< CppType >::Iterator | ( | ) |
Default constructor.
|
explicit |
Creates a Gst::Iterator wrapper for a GstIterator object.
The underlying castitem will be freed with the Gst::Iterator destruction if a take_ownership value of true is given.
| castitem | The C instance to wrap. |
| take_ownership | Whether to take over the underlying C object. If true, C object is freed when wrapper is destroyed. |
|
virtual |
Moves to the next iterator item.
Reimplemented from Gst::IteratorBase< CppType >.
| Glib::RefPtr<CppType> Gst::Iterator< CppType >::operator* | ( | ) | const |
Dereferences the iterator and obtains the underlying Glib::RefPtr<>.
| Iterator<CppType>& Gst::Iterator< CppType >::operator++ | ( | ) |
Prefix auto-increment operator.
It advances to the next item in the iterator. It is faster than the postfix operator.
| std::runtime_error | (if a Gst::ITERATOR_ERROR is encountered or if a concurrent update to the iterator occurs while it iterates). |
| Iterator<CppType> Gst::Iterator< CppType >::operator++ | ( | int | ) |
Postfix auto-increment operator.
It advances to the next item in the iterator.
| std::runtime_error | (if a Gst::ITERATOR_ERROR is encountered or if a concurrent update to the iterator occurs while it iterates). |
| CppType* Gst::Iterator< CppType >::operator-> | ( | ) | const |
Accesses underlying object member through the RefPtr<>.
