Detailed Description

This group provides optimized to work with C native array (whatever the running OS).

Most of these functions uses information of the type provided by the type_info<T> structure to optimize or not the array operations. Particularly, they uses the is_deep definition to know if a value may be copied byte-per-byte or need more complex processing because of its data structure. Any non-scalar type is basically considered as non-deep but you may change this behavior by specializing the type_info for your own type, MyType in the example below:

template <> struct type_info<MyType>: public class_t<MyType> {
 enum { is_deep = true };
}

Function Documentation

template<class T >

void elm::array::clear	(	T *	target,
		int	size
	)

Set the items of an array of the given size to 0.

Parameters

target	Target array.
size	Size of both arrays.

template<class T >

void elm::array::copy	(	T *	target,
		const T *	source,
		int	size
	)

Copy source array of the given size to the target as fast as possible. The arrays must not overlap.

Parameters

target	Target array.
source	Source array.
size	Size of both arrays.

template<class T >

void elm::array::move	(	T *	target,
		const T *	source,
		int	size
	)

Copy source array of the given size to the target as fast as possible. The arrays may overlap.

Parameters

target	Target array.
source	Source array.
size	Size of both arrays.

template<class T >

void elm::array::set	(	T *	target,
		int	size,
		const T &	v
	)

Set the items of an array of the given size to the given value, as fast as possible.

Parameters

target	Target array.
size	Size of both arrays.
v	Value to set.
