BloombergLP::bdlat::ArrayUtil::manipulateElementByCategory

Invoke the specified manipulator on the address of the element at the specified index of the specified array and on a prvalue of the category tag type for the dynamic category of the element. See {bdlat_typecategory|Category Tags and Enumerators} for documentation about category tags. Return the value from the invocation of manipulator. The manipulator must be a manipulator functor. See {bdlat_typecategory|MANIPULATOR Functors} for the requirements on manipulator. The behavior is undefined unless 0 <= index < bdlat_ArrayFunctions::size(array).
