Member Function Documentation

ArrayBase& assign	(	const T &	v,
		uint32_t	end,
		uint32_t	stride = 1,
		uint32_t	start = 0
	)		[inherited]

Sets linear slice of elements to value.

Parameters:

[in]	v	value to be copied as new content
[in]	end	end index (exclusive)
[in]	stride	index stride amount
[in]	start	start index (inclusive)

void own

(

)

[inherited]

Ensures ownership of elements.

If the array is not already the sole owner, new memory is allocated and the previously referenced array elements are copied.

void resize	(	uint32_t	newSize,
		const T &	c = T()
	)		[inherited]

Resizes number of elements in array.

If the new size is less than the old size, then elements are truncated. If the new size is greater than the old size, then the argument value is copied into the additional elements.
