alib::boxing::VTableOptimizationTraits< TMapped, TIsArray > Struct Template Reference

Description:

template<typename TMapped, bool TIsArray>
struct alib::boxing::VTableOptimizationTraits< TMapped, TIsArray >

Method Get of the default version of this struct creates a VTable dynamically. For this, a corresponding templated Singleton of type VTableUnoptimized<TMapped, TIsArray> is returned.

For optimization purposes (code size as well as execution performance), this struct might be specialized for selected mapped types to return a static singleton object.

Specializations can be performed with preprocessor macros

• ALIB_BOXING_VTABLE_DECLARE,
• ALIB_BOXING_VTABLE_DECLARE_ARRAYTYPE, and
• ALIB_BOXING_VTABLE_DEFINE.

Furthermore, with debug-compilations, such spezializations should be "registered" during bootstrap using macro ALIB_BOXING_BOOTSTRAP_VTABLE_DBG_REGISTER.

Specializations for all C++ fundamental types are given. Furthermore, various different ALib Modules provide such specializations for types they introduced and that are boxed.
