Public Member Functions
	ezArrayBase ()
	Constructor.

	~ezArrayBase ()
	Destructor.

void	operator= (const ezArrayPtr< const T > &rhs)
	Copies the data from some other contiguous array into this one.

	operator ezArrayPtr< const T > () const
	Conversion to const ezArrayPtr.

	operator ezArrayPtr< T > ()
	Conversion to ezArrayPtr.

bool	operator== (const ezArrayBase< T, Derived > &rhs) const
	Compares this array to another contiguous array type.

	EZ_ADD_DEFAULT_OPERATOR_NOTEQUAL (const ezArrayBase< T, Derived > &)

bool	operator< (const ezArrayBase< T, Derived > &rhs) const
	Compares this array to another contiguous array type.

bool	operator< (const ezArrayPtr< const T > &rhs) const
	Compares this array to another contiguous array type.

const T &	operator[] (ezUInt32 uiIndex) const
	Returns the element at the given index. Does bounds checks in debug builds.

T &	operator[] (ezUInt32 uiIndex)
	Returns the element at the given index. Does bounds checks in debug builds.

void	SetCount (ezUInt32 uiCount)
	Resizes the array to have exactly uiCount elements. Default constructs extra elements if the array is grown.

void	SetCount (ezUInt32 uiCount, const T &fillValue)
	Resizes the array to have exactly uiCount elements. Constructs all new elements by copying the FillValue.

template<typename = void>
void	SetCountUninitialized (ezUInt32 uiCount)
	Resizes the array to have exactly uiCount elements. Extra elements might be uninitialized.

void	EnsureCount (ezUInt32 uiCount)
	Ensures the container has at least uiCount elements. Ie. calls SetCount() if the container has fewer elements, does nothing otherwise.

ezUInt32	GetCount () const
	Returns the number of active elements in the array.

bool	IsEmpty () const
	Returns true, if the array does not contain any elements.

void	Clear ()
	Clears the array.

bool	Contains (const T &value) const
	Checks whether the given value can be found in the array. O(n) complexity.

void	InsertAt (ezUInt32 uiIndex, const T &value)
	Inserts value at index by shifting all following elements.

void	InsertAt (ezUInt32 uiIndex, T &&value)
	Inserts value at index by shifting all following elements.

void	InsertRangeAt (ezUInt32 uiIndex, const ezArrayPtr< const T > &range)
	Inserts all elements in the range starting at the given index, shifting the elements after the index.

bool	RemoveAndCopy (const T &value)
	Removes the first occurrence of value and fills the gap by shifting all following elements.

bool	RemoveAndSwap (const T &value)
	Removes the first occurrence of value and fills the gap by swapping in the last element.

void	RemoveAtAndCopy (ezUInt32 uiIndex, ezUInt32 uiNumElements=1)
	Removes the element at index and fills the gap by shifting all following elements.

void	RemoveAtAndSwap (ezUInt32 uiIndex, ezUInt32 uiNumElements=1)
	Removes the element at index and fills the gap by swapping in the last element.

ezUInt32	IndexOf (const T &value, ezUInt32 uiStartIndex=0) const
	Searches for the first occurrence of the given value and returns its index or ezInvalidIndex if not found.

ezUInt32	LastIndexOf (const T &value, ezUInt32 uiStartIndex=ezInvalidIndex) const
	Searches for the last occurrence of the given value and returns its index or ezInvalidIndex if not found.

T &	ExpandAndGetRef ()
	Grows the array by one element and returns a reference to the newly created element.

T *	ExpandBy (ezUInt32 uiNumNewItems)
	Expands the array by N new items and returns a pointer to the first new one.

void	PushBack (const T &value)
	Pushes value at the end of the array.

void	PushBack (T &&value)
	Pushes value at the end of the array.

void	PushBackUnchecked (const T &value)
	Pushes value at the end of the array. Does NOT ensure capacity.

void	PushBackUnchecked (T &&value)
	Pushes value at the end of the array. Does NOT ensure capacity.

void	PushBackRange (const ezArrayPtr< const T > &range)
	Pushes all elements in range at the end of the array. Increases the capacity if necessary.

void	PopBack (ezUInt32 uiCountToRemove=1)
	Removes count elements from the end of the array.

T &	PeekBack ()
	Returns the last element of the array.

const T &	PeekBack () const
	Returns the last element of the array.

template<typename Comparer >
void	Sort (const Comparer &comparer)
	Sort with explicit comparer.

void	Sort ()
	Sort with default comparer.

T *	GetData ()
	Returns a pointer to the array data, or nullptr if the array is empty.

const T *	GetData () const
	Returns a pointer to the array data, or nullptr if the array is empty.

ezArrayPtr< T >	GetArrayPtr ()
	Returns an array pointer to the array data, or an empty array pointer if the array is empty.

ezArrayPtr< const T >	GetArrayPtr () const
	Returns an array pointer to the array data, or an empty array pointer if the array is empty.
