Description

accessElementByCategory

Invoke the specified accessor on the non‐modifiable 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 accessor. The accessor must be an accessor functor. See {`bdlat_typecategory`|`ACCESSOR` Functors} for the requirements on accessor. The behavior is undefined unless 0 <= index < bdlat_ArrayFunctions::size(array).

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).
