#include <iterator.h>
Public Member Functions | |
Iterator () | |
Default constructor. | |
Iterator (GstIterator* castitem, bool take_ownership=true) | |
Creates a Gst::Iterator wrapper for a GstIterator object. | |
IteratorResult | next () |
Moves to the next iterator item. | |
Glib::RefPtr<CppType> | operator* () const |
Dereferences the iterator and obtains the underlying Glib::RefPtr<>. | |
CppType* | operator-> () const |
Accesses underlying object member through the RefPtr<>. | |
Iterator<CppType>& | operator++ () |
Prefix auto-increment operator. | |
Iterator<CppType> | operator++ (int) |
Postfix auto-increment operator. |
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.
Gst::Iterator<CppType>::Iterator | ( | GstIterator< CppType > * | castitem, | |
bool | take_ownership = true | |||
) |
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. |
IteratorResult Gst::Iterator<CppType>::next | ( | ) | [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<>.
Reimplemented from Gst::IteratorBasic<CppType>.
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). |
Reimplemented from Gst::IteratorBasic<CppType>.
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). |
Reimplemented from Gst::IteratorBasic<CppType>.
CppType* Gst::Iterator<CppType>::operator-> | ( | ) | const |
Accesses underlying object member through the RefPtr<>.
Reimplemented from Gst::IteratorBasic<CppType>.
