Append() [1/2]

MAXON_ATTRIBUTE_FORCE_INLINE ResultRef<T> Append

(

ARGS &&...

args

)

Adds a new element at the end of the buffer and moves the content of x to it.

Parameters

[in]

args

Values to be forwarded.

Returns

Element reference or OutOfMemoryError if the initial allocation failed.

Append() [2/2]

MAXON_ATTRIBUTE_FORCE_INLINE ResultPtr<T> Append

(

const std::initializer_list< T > &

values

)

Appends new elements at the end of the array.

Parameters

[in]

values

Initializer list with values to be copied.

Returns

Element pointer or OutOfMemoryError if the allocation failed.

operator[]() [1/2]

MAXON_ATTRIBUTE_FORCE_INLINE const T& operator[]

(

Int

idx

)

const

Array (subscript) operator for non-const objects. Index 0 is the oldest entry.

Parameters

[in]

idx

Element index (if it's out of bounds you will get an error in debug code only, otherwise it will crash).

Returns

Array element.

operator[]() [2/2]

MAXON_ATTRIBUTE_FORCE_INLINE T& operator[]

(

Int

idx

)

Array (subscript) operator for non-const objects. Index 0 is the oldest entry.

Parameters

[in]

idx

Element index (if it's out of bounds you will get an error in debug code only, otherwise it will crash).

Returns

Array element.

GetFirst() [1/2]

MAXON_ATTRIBUTE_FORCE_INLINE const T* GetFirst

(

)

const

Returns a pointer to the first element in the ring buffer (which is different from the first element in the array).

Returns

Pointer to the first element (nullptr if the buffer is empty).

GetFirst() [2/2]

MAXON_ATTRIBUTE_FORCE_INLINE T* GetFirst

(

)

Returns a pointer to the first element in the ring buffer (which is different from the first element in the array).

Returns

Pointer to the first element (nullptr if the buffer is empty).

GetLast() [1/2]

MAXON_ATTRIBUTE_FORCE_INLINE const T* GetLast

(

)

const

Returns a pointer to the last element in the ring buffer (which is different from the last element in the array).

Returns

Pointer to the last element (nullptr if the buffer is empty).

GetLast() [2/2]

MAXON_ATTRIBUTE_FORCE_INLINE T* GetLast

(

)

Returns a pointer to the last element in the ring buffer (which is different from the last element in the array).

Returns

Pointer to the last element (nullptr if the buffer is empty).

Reset()

void Reset

(

void

)

Deletes all elements (calls destructors and frees memory).

Flush()

void Flush

(

void

)

Deletes all elements, but doesn't free memory (calls destructors though).

Begin() [1/2]

ConstIterator Begin

(

)

const

Gets an iterator for the first element. When you modify the array Begin() will change, it is not a constant value.

Returns

Iterator for the first element (equal to End() if the array is empty).

Begin() [2/2]

Iterator Begin

(

)

Gets an iterator for the first element. When you modify the array Begin() will change, it is not a constant value.

Returns

Iterator for the first element (equal to End() if the array is empty).

End() [1/2]

ConstIterator End

(

)

const

Gets an iterator for the end (End() - 1 is the last element if the array is not empty). When you modify the array End() will change, it is not a constant value.

Returns

Iterator for the array end (this is behind the last element).

End() [2/2]

Iterator End

(

)

Gets an iterator for the end (End() - 1 is the last element if the array is not empty). When you modify the array End() will change, it is not a constant value.

Returns

Iterator for the array end (this is behind the last element).
