Witrynaoverview. ctom is a single-header library which allows you to define compile-time object models, statically analze their structure, and use this to emit and parse various serialization formats. ctom supports value-types, sequence-types and object-types. Instead of iterating over json or yaml node trees, you can statically declare your object ... PImpl. "Pointer to implementation" or "pImpl" is a C++ programming technique [1] that removes implementation details of a class from its object representation by placing them in a separate class, accessed through an opaque pointer: This technique is used to construct C++ library interfaces with … Zobacz więcej In simple cases, both pImpl and factory method remove compile-time dependency between the implementation and the users of the class interface. Factory method creates a hidden … Zobacz więcej Use of pImpl requires a dedicated translation unit (a header-only library cannot use pImpl), introduces an additional class, … Zobacz więcej
