template <class T>
class Buffer : private Moveable< Buffer<T> >
T Type of elements stored in Buffer.
Buffer is a simple class used to manage a fixed size plain old C dynamically allocated vector of elements of a specified type. The size of the buffer is specified as a constructor parameter and it can be also reallocated with new size, while loosing all current data.
Buffer is a moveable type with pick (only) transfer semantics. Calling methods of picked Buffer is logic error with the exceptions of:
void Alloc(int size);
void Alloc(int size, const T& in);
void Clear();
void operator=(pick_ Buffer& v);
Buffer()
Constructs an empty buffer.
Buffer(size_t size)
Constructs the Buffer with a size number of elements.
T must have default constructor.
Buffer(size_t size, const T& init)
Constructs the Buffer initializing the size elements to the specified value init.
T must have default constructor.
Buffer(pick_ Buffer& v)
Pick constructor. Destroys source container v.
~Buffer()
Default destructor.
void operator=(pick_ Buffer& v)
Pick operator. Source buffer v is destroyed.
operator T*()
Returns a pointer to the first element of the Buffer or NULL if the Buffer is empty.
operator const T*() const
Returns a pointer to the first element of the Buffer or NULL if the Buffer is empty.
T *operator~()
Returns a pointer to the first element of the Buffer or NULL if the Buffer is empty.
const T *operator~() const
Returns a pointer to the first element of the Buffer or NULL if the Buffer is empty.
void Alloc(size_t size)
Clears the buffer and allocates it with the new size size. All current elements are lost.
T must have default constructor.
void Alloc(size_t size, const T& in)
Clears the buffer and allocates it with the new size size, using the initialization value in. All current elements are lost.
T must have deep copy constructor.
void Clear()
Clears the buffer to the same state as default constructor. All current elements are destroyed.
