void casa::Copy_global_functions_copy::objcopy	(	T *	to,
		const T *	from,
		size_t	n
	)		[inline]

inline void objmove(const void** to, const void*const <em>from, size_t n) { memmove(to, from, n*sizeof(void)); } inline void objmove(const char** to, const char*const <em>from, size_t n) { memmove(to, from, n*sizeof(char)); } inline void objmove(void** to, void*const <em>from, size_t n) { memmove(to, from, n*sizeof(void)); } inline void objmove(char** to, char*const <em>from, size_t n) { memmove(to, from, n*sizeof(char)); } The non-general function to copy n objects from one place to another. Strides may be specified, i.e. you may copy from every fromStride-th position into every toStride-th one.

Objcopy does not take an overlap of source and destination into account. Objmove should be used if that is an issue.

An exception will be thrown if the source or the destination does not exist or if the strides are non-positive.

template<class T >

void casa::Copy_global_functions_copy::objmove	(	T *	to,
		const T *	from,
		size_t	n
	)		[inline]

The general function to copy n objects from one place to another if overlap between to and from fields is possible.

Strides may be specified, i.e. you may copy from every fromStride-th position into every toStride-th one. The function will call std::copy() when possible. Objmove works correctly if the source and destination overlap in any way. An exception will be thrown if the source or the destination does not exist (and n is non-zero) or if the strides are non-positive.

Thrown Exceptions

• AipsError

	)		[inline]

Do the moves from the right.

template<class T >

void casa::Copy_global_functions_copy::objset	(	T *	to,
		const T	fillValue,
		size_t	n
	)		[inline]

inline void objcopy(const void** to, const void*const <em>from, size_t n) { memcpy(to, from, n*sizeof(void)); } inline void objcopy(const char** to, const char*const <em>from, size_t n) { memcpy(to, from, n*sizeof(char)); } inline void objcopy(void** to, void*const <em>from, size_t n) { memcpy(to, from, n*sizeof(void)); } inline void objcopy(char** to, char*const <em>from, size_t n) { memcpy(to, from, n*sizeof(char)); } Fill n elements of an array of objects with the given value, optionally with a stride. Note that the fillValue is passed by value.

An exception will be thrown if the destination array does not exist or if the stride is non-positive.
