template<class T >
void casacore::Copy_global_functions_copy::objcopy ( T *  to,
const T *  from,
size_t  n 
)
inline 

 The non-general function to copy <tt>n</tt> 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/objcopyctor does not take an overlap of source and destination into account. Objmove should be used if that is an issue.

Objcopyctor copy objects from from by calling copy constructor on each element in to.

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

void casacore::Copy_global_functions_copy::objmove ( T *  to,

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.

Do the moves from the right.

template<class T >
void casacore::Copy_global_functions_copy::objset ( T *  to,
const T  fillValue,
size_t  n 
)
inline 

Fill <tt>n</tt> 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.
